About the Model 493.72 Digital I/O Board
The Model 493.72 Digital I/O board is a
transition board that provides 16 digital
inputs and 16 digital outputs.
The Model 493.72 board is typically used
with the Model 494.31 (high current) or the
Model 493.31 (low current) breakout boxes.
Digital I/O Transition Board
Cables connected to J3 and J4 connect digital
input and output circuits on the Model
493.72 board to the DI/O breakout box.
Digital Inputs (J3)–can be used to trigger
test events within controller applications.
Digital input signals are monitored by
controller software. The Model 493.72 board
includes configurable debounce circuits for
digital inputs.
Digital Outputs (J4)–can be used to control
external devices. Digital output signals are
generated by controller software. These low-
current output signals drive output devices
that are connected to a DI/O breakout box.
Model 494.31 16-Channel High-Current DI/O
Breakout Box
Provides terminal plug connections for
external devices, connections for external
input/output power supplies, and high-
current switching circuits for digital outputs.
Model 493.31 16-Channel Low-Current DI/O
Breakout Box
