Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1771-ID16 is an isolated discrete input module from Allen-Bradley's PLC-5 series. It provides 16 individually isolated channels accepting 120 V AC or DC signals. Installed in a 1771-A1B through -A4B or later I/O chassis, it converts field digital inputs (such as limit switches or pushbuttons) into logic signals for the controller. The module incorporates selectable input filtering to suppress transient noise. 1771-ID16 modules were discontinued as of December 31, 2019.
Best Suited For
- PLC-5 systems requiring 120 V AC/DC discrete inputs
- Applications with mixed AC/DC field devices on one module
- Installations needing channel-to-channel isolation
- Environments with electrical noise where input filtering is required
