Model 493.72 board
connections
A cable from J10 on the DI/O breakout box connects all 16 input-device
signals to J3 on the Model 493.72 board. Each digital input on the Model
493.72 board has an opto isolator that is controlled by the input device.
Note Digital inputs have 20-ms debounce circuits. If required, install
jumpers on the Model 493.72 board to shorten the debounce times.
For more information The connection drawings show pin assignments for input 1. For a complete
