Digital I/O Module
The main functions of the digital I/O module are as follows:
-
To monitor binary sensors and switches via four 24 Vdc sink/source inputs
-
To control devices like relays, signaling lights, or controller binary inputs via two 0.5 A, 24 Vdc transistor-type outputs
-
To capture statistical operational data of the I/O module:
-
Number of power cycles
-
Number of detected events
-
Time the module is on
-
-
To perform I/O Channel testing and simulation
The reference number is TPRDG4X2.
The digital I/O module is connected:
-
Upstream to the 24 Vdc source needed to power the downstream actuators
-
Input channel: downstream to a binary sensor or switch
-
Output channel: downstream to the 24 Vdc input of the actuator
Refer to Avatar Wiring Schematics for module wiring.
Devices connected to the digital I/O module must be protected against short-circuits by external means like fuses. Use one 0.5 A Type T fuse per output. Recommended are Littlefuse 215, 218, FLQ, or FLSR series or equivalent.
The digital I/O module communicates with the bus coupler, sending operational data and receiving commands.
