Overview of PACSystems™ RX3i IC694MDL660

The IC694MDL660 is a 24VDC Positive/Negative Logic Input module for the PACSystems™ RX3i system. This module offers 32 discrete input points, arranged in four isolated groups of 8 inputs. It can handle input voltages ranging from 0 to 30V DC and supports both positive and negative logic inputs.

The inputs are isolated from each other in groups, with each group sharing a common connection. The isolation ensures that the input signals do not interfere with each other, providing high reliability and protection in industrial environments.
