Overview

The DC Digital Input module (900G32-0301) provides 32 inputs separated into 2 groups of 16 channels each. Each group has a pair of screw terminals for the COM connection. DC power applied between the common terminal and an input causes the input to turn ON. Each channel on the module has a green LED state indicator to show when a digital input is ON. A green blinking status LED on the module indicates when the module is being scanned, while a red status LED lights up when module diagnostics exist. Logic in the controller allows the state to be inverted when necessary. The module requires a Euro style 36-terminal terminal block.
