Installing the USB-PDISO8
UnpackingAs with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the device from its packaging, ground yourself using a wrist strap or by simply
touching the computer chassis or other grounded object to eliminate any stored static charge.
Contact us immediately if any components are missing or damaged.

Installing the software
Refer to the MCC DAQ Quick Start and the USB-PDISO8 product page on our website for information about
the software supported by the USB-PDISO8.
Install the software before you install your device
The driver needed to run the USB-PDISO8 is installed with the software. Therefore, you need to install thesoftware package you plan to use before you install the hardware.

Connecting the external power supply
Power to the USB-PDISO8 is provided with the +9 V external power supply (CB-PWR-9). You must connect
the external power supply before connecting the USB cable to the USB-PDISO8 and your computer.
If you are connecting more than one MCC USB device, make sure that you provide adequate power to eachdevice. Refer to Power limitations using multiple USB-PDISO8 devices Error! Bookmark not defined..
To connect the power supply to your USB-PDISO8, connect the external power cord to the power connector
labeled POWER IN on the USB-PDISO8 enclosure (PWR IN on the board). Refer to Figure 2 on page 8 for thelocation of this connector.
The green PWR LED lights when +9 V power is supplied to the USB-PDISO8. If the voltage supply is less than
+6.5 V or more than +12.5 V, the PWR LED does not light.
Do not connect external power to the POWER OUT connector
The power connector labeled POWER OUT on the enclosure (PWR OUT on the board) is used to provide power
to an additional MCC USB device. If you connect the external power supply to the POWER OUT connector, theUSB-PDISO8 does not receive power, and the PWR LED does not light.

Installing the hardware
Connect the USB-PDISO8 using the cable provided to a USB port on a computer running Windows. Windows
finds and installs the device driver automatically and notifies you that the device is ready to use.
The USB LED turns on after the device is successfully installed.
You can connect up to four compatible MCC USB products in a daisy-chain configuration to a USB port onyour computer.
If the USB LED turns off
If communication is lost between the device and the computer, the USB LED turns off. To restore
communication, disconnect the USB cable from the computer and then reconnect it. This should restore
communication, and the USB LED should turn on.

Functional Details

USB OUT connector
The USB OUT connector is a downstream hub output port intended for use with other MCC USB products only.
The USB hub is self-powered, and can provide 100 mA maximum current at 5 V.
For information on daisy chaining to other MCC USB devices, refer to Daisy chaining additional devices to the
USB-PDISO8 on page 12.

POWER IN connector
The USB-PDISO8 requires between 6.5 V and 12.5 V of external power. An external power connection isrequired to activate the relays and to run tests in InstaCal.
To supply external power, connect the POWER IN connector to the supplied +9 V external power supply(CB-PWR-9).
The USB specification allows high-power devices to draw up to 725 mA. When all eight relays are energized,
the combined current draw exceeds the maximum allowed for high-power USB devices. Therefore, external
power is required.

POWER OUT connector
Use the POWER OUT connector to provide power to additional daisy chained MCC USB devices from a single
external power supply. Refer to Power limitations using multiple USB-PDISO8 devices Error! Bookmark notdefined. for more information. A user-supplied custom cable is required to daisy chain multiple devices.

Screw terminals and relays
Connect external devices to the relay contacts using the 24 screw terminals on the USB-PDISO8. Each relay has
a normally closed (NC), common (C), and normally open (NO) contact. Figure 3 shows the screw terminals ona typical relay channel.

Figure 3. Typical relay channel

Each screw terminal is identified with a label on the board and on the underside of the enclosure lid.
Caution! Before connecting wires to the screw terminals, turn off the power to the USB-PDISO8, and makesure that the signal wires do not contain live voltages.
Use 12 AWG to 22 AWG wire to connect field devices. Properly insulate the wires to avoid any
short circuit to the other connections, ground, or other points on the board.

10USB-PDISO8 User's Guide

Functional Details

Caution! Keep the length of stripped wire at a minimum to avoid a short to the enclosure! When connecting
your field wiring to the screw terminals, use the strip gage on the terminal strip, or strip to 5.5 7.0 mm (0.215" to 0.275") long.
Form C relay output
A schematic for Form C relay contacts is shown in Figure 4. The Form C relay has a C, NO, and NC contact.
When a (0) is written to the output bit, the C and NC are in contact.
When a (1) is written to the output bit, the C and NO are in contact.

Input 6 terminal A and input 6 terminal B (IP6A and IP6B)
Input 7 terminal A and input 7 terminal B (IP7A and IP7B)

A schematic of a single channel is shown in Figure 5. Each signal is applied to a bridge rectifier so that the
input is not polarity-sensitive. Each input channel can be driven by either AC (50 - 1000 Hz) or DC voltage.
The eight optically isolated (500 V) inputs can be read back as a single byte. Each input has a softwarecontrolled filter with a time constant of 5 ms (200 Hz). The filter is required for AC inputs, and recommended
for almost all DC inputs. Unless you have a good reason to turn off a filter, MCC recommends that you enableit.
You can enable and disable (default) each input filter by selecting the device and then selecting
Install»Configure in InstaCal.

Extending the input range
You can extend the input range beyond the 5 to 30 V specified by adding an external resistor. Figure 7 showsthe external resistor (Rext).
The equation Rext = 100 * (Vin – 30) calculates the resistor value for a given Vin.
Make sure the external resistor is capable of handling the power generated by the input. Calculate the power
requirement in watts (Pw) using the equation Pw = Rext/10000.

Figure 7. External resistor added to extend the input range

Daisy chaining additional devices to the USB-PDISO8
Daisy-chained USB-PDISO8 devices connect to the USB bus through the high-speed hub on the USB-PDISO8.
You can daisy chain up to four MCC USB devices that support daisy-chain configurations to a single USB 2.0
port or USB 1.1 port on your computer.
Perform the following procedure to daisy chain multiple devices together. A user-supplied custom cable isrequired to daisy chain multiple devices.
The device connected to the computer is referred to as the host device.
Each additional device that you want to daisy chain to the host USB-PDISO8 is referred to as a slave
device.

This procedure assumes you already have a host device connected to a computer and to an external powersource.
1.

Connect the POWER OUT connector on the host device to the POWER IN connector on the slave device.
This step is required only if you plan to daisy chain power to another device.

2.

Connect the USB OUT connector on the host device to the USB IN connector on the slave device.

3.

To add another device, repeat steps 1-2 by connecting the slave device to another slave device.

Note that the last device in the chain is supplied with external power.
When daisy chaining additional MCC USB products to the USB-PDISO8, make sure that you provide adequate
power to each device that you connect. The USB-PDISO8 is powered with a 9 VDC nominal, 1.67 A external
power supply.
When connecting multiple devices, power supplies with higher current capability, such as the CB PWR-9V3A,
are available from MCC.
12

USB-PDISO8 User's Guide

Functional Details

Supply current
Running one USB-PDISO8 with all relays on draws 820 mA from the 1.67 A supply. When using theUSB-PDISO8 under full load conditions, you cannot daisy chain additional MCC USB products unless you
supply external power to each device in the chain.
If you are not sure how much current your application requires, we recommend that you provide separate power
to each MCC USB product that you connect.

Voltage drop
A drop in voltage occurs with each device connected in a daisy chain system. The voltage drop between themodule power supply input and the daisy chain output is 0.5 V maximum. Factor in this voltage drop when you
configure a daisy chain system to ensure that at least 6.5 VDC is provided to the last device in the chain.
Always provide a separate power supply when the USB-PDISO8 is the last device in the chain.

Relay contact protection circuit for inductive loads
When you connect an inductive load to a relay, energy stored in the inductive load can induce a large voltage
surge when you switch the relay. This voltage can severely damage the relay contacts. To limit the voltage
surge across the inductive load in a DC circuit, install a kickback diode across the inductive load. Refer to thecontact protection circuit in Figure 9. For AC loads, install a metal oxide varistor (MOV).
