Description
Product Description
The IC694MDL260 is a high-performance 32-channel AC discrete input module engineered for the PACSystems RX3i platform. It provides reliable 120 VAC signal detection for a wide range of industrial control applications, offering robust isolation and diagnostic feedback.
Key Features and Functionality
-
32 discrete input points organized into 4 isolated groups, 8 channels per group
-
Positive logic: ON state recognized when voltage is applied
-
High isolation between groups: 1500 VAC typical; shared common reference within groups
-
Hot-swap capable on RX3i Universal Backplane
-
Individual LEDs for each input channel plus red/green terminal block status indicators
-
Supports diagnostic reporting of field-side terminal block presence
