INSTRUCTION MANUALONE-SHOT PULSE OUTPUT MODULE(NPN transistor output, 16 points)

BEFORE USE ....
Thank you for choosing us. Before use, please check contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact our sales office or representatives.
■ PACKAGE INCLUDES:
One-shot pulse output module............................................(1)■ MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
■ INSTRUCTION MANUALThis manual describes necessary points of caution whenyou use this product, including installation, connection andbasic maintenance procedures.

POINTS OF CAUTION■ CONFORMITY WITH EU DIRECTIVES• The equipment must be mounted inside the instrument
panel of a metal enclosure.
• The actual installation environments such as panel configurations, connected devices, connected wires, may affect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure the CE conformity.

MODELR3-PD16A■ ENVIRONMENT• Indoor use.
• When heavy dust or metal particles are present in theair, install the unit inside proper housing with sufficientventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -10 to +55°C(14 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■ WIRING• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
■ AND ....
• When the pause period set in the PLC/PC is long, internal
data of R3-PD16A will be cleared due to communication
timeout. In order to hold the internal data, set the timeout period so as to be longer than the pause period via thePC configurator software (model:R3CON).

INSTALLATION
Use the Installation Base (model: R3-BSx).

■ HOT SWAPPABLE MODULES• Replacing the module does not affect other modules on
the same base. Thus, the module can be replaced whilethe power is ON. However, replacing multiple modules
at once may greatly change live voltage levels. We highly
recommend to replace them one by one.
• ON/OFF control output mode and One-shot output mode
have the function of preventing erroneous output rightafter hot swapping modules. Data is synchronized withdata stored in the interface module in the initial communication after hot swapping.	Data will not be output from a channel even if ‘1’ is previously written in Do before hot swapping or the PLC/PCwrites ‘1’ to Do when communication has started after hotswapping. Be sure to write ‘0’ then ‘1’ to Do in the initialcommunication.	When R3-PD16A is used in combination with a Modbus
interface module (model: R3-NM1, R3-NE1, etc.) that
does not support cyclic communication, be sure to write
output data immediately before hot swapping.
■ GENERAL PRECAUTIONS• DO NOT set the switches on the module while the poweris supplied. The switches are used only for maintenancewithout the power.

EXAMPLE OF OPERATION MODESThe operation mode can be set with the side DIP switch. Also output hold and output OFF at a continuous output mode canbe set.
■ ONE-SHOT OUTPUT MODE (1 through 4 show changes after Do 1 is completed. 5 through 10 changes Do 1 during output state.)
Example of I/O Mode is in Output Operation. (SW2-7: OFF)
(1) Output data Do 1 changes from 0 to 1.
(2) After Do 1’s rising edge, Ch1’s one-shot output turns ON for a fixed period of time (SW1’s time set).
(3) After one-shot output completion, Di 1 (Ch1 output completed status) changes from 0 to 1.
(4) When Do 1 changes from 1 to 0, Di 1 changes from 1 to 0.
(5) Output Data Do 1 changes from 0 to 1 again.
(6) After Do 1’s rising edge, Ch1’s one-shot output turns ON for a fixed period of time (SW1’s time set).
(7) (8) (9) During one-shot output is ON, Do 1 changes from 0 to 1 to 0.
(10) Since Do 1 changes to 0 during one-shot output is 1, Di 1 (Ch1 output completion status) doesn’t change.

■ ON/OFF CONTROL OUTPUT MODE• Data Length: 16 bits
Example that ON/OFF control outputs sequentially Ch1 to Ch2 to Ch2 is shown below.
Example of when I/O Mode is in Output Operation (SW2-7: OFF) and ON/OFF Control channel is Not Swapped (SW2-8: OFF).
(1) Output data Do 1 changes from 0 to 1.
(2) After Do 1’s rising edge, Ch1’s one-shot output turns ON for a fixed period of time (SW1’s time set).
(3) After one-shot output completion, Di 1 (Ch1 output completed status) changes from 0 to 1.
(4) Do 1 changes from 1 to 0.
(5) When output data Do 2 changes from 0 to 1, Di 1 will change from 1 to 0.
(6) After Do 2’s rising edge, Ch2’s one-shot output turns ON for a fixed period of time (SW1’s time set).
(7) After Ch2’s one-shot output completion, Di 2 changes from 0 to 1.
(8) When Do 1 changes 0 to 1 during Do 2 is 1, Di 2 changes 1 to 0 (output data reset).
(9) Do 1 changes from 1 to 0.
(10) After Do 1’s sinking edge, Ch2’s one-shot output turns ON for a fixed period of time (SW1’s time set).
(11) After Ch2’s one-shot output completion, Di 2 changes from 0 to 1.

If both are in error, the module holds the signal andstands by until one of the communications recovers.
• Output OFF	If both are in error, the module outputs OFF signals andstands by until one of the communications recovers.	At the startup, it outputs OFF until the communication isestablished and normal data is received.
