Product Description

Isolated AC/DC input monitoring in 1771 control systems

This module is used to bring 120V AC/DC field input signals into a 1771 I/O system. It applies isolated input monitoring for switch-based control signals and installs into a compatible 1771 series I/O chassis. :contentReference[oaicite:2]{index=2}

Input handling and channel design

- 16 inputs per module
- Nominal input voltage is 120V AC/DC
- Input voltage range is 74-138V AC, 47-63Hz; 105-138V DC
- Isolation voltage is 1500V AC rms channel-to-channel and channel-to-backplane
- Backplane current requirement is 75mA maximum :contentReference[oaicite:3]{index=3}

Filter and chassis operation

The module uses customer-selectable input filtering to limit the effects of voltage transients caused by contact bounce or radiated electrical noise. AC input on-to-off delay is selectable at 9ms or 18ms. DC input on-to-off delay is 9ms. The module receives power through the 1771 I/O chassis backplane. :contentReference[oaicite:4]{index=4}

Typical control uses

- Limit switches
- Float switches
- Selector switches :contentReference[oaicite:5]{index=5}
