Screw terminals and relays
Connect external devices to the relay contacts using the USB-ERB08 board's eight sets of screw terminals. Eachrelay has a normally closed (NC), common (C), and normally open (NO) contact. Figure 8 shows the screw
terminals on a typical relay channel.

Figure 8. 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-ERB08, and makesure that the signal wires do not contain live voltages.
Use 12-22 AWG wire for your signal connections. Properly insulate the wires to avoid any shortcircuit to the other channels, ground, or other points on the board.
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 in.) long.

Relay configuration
You can install a pull-up or pull-down resistor at the NO and NC terminals on each relay. Note that the pull-up
resistors are tied to the 5 V power and should be considered when calculating the power budget. The relay
configuration is shown in Figure 9

Figure 9. Relay configuration

The relay contacts associated that are with each relay location are listed in the table below.

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 10. For AC loads, install a metal oxide varistor (MOV).

Daisy chaining additional relays to the USB-ERB08
Daisy-chained USB-ERB08 devices connect to the USB bus through the high-speed hub on the USB-ERB08.
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-ERB08 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.

Power limitations using multiple USB-ERB08 devices
When daisy chaining the USB-ERB08 to other MCC USB devices, make sure that you provide adequate power
to each device that you connect. The USB-ERB08 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.

Voltage drop
A drop in voltage occurs with each board connected in a daisy chain system. The voltage drop between the
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 6.0 VDC is provided to the last board in the chain.
