Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1771-ID is an Allen-Bradley PLC-5 series isolated digital input module providing six individually isolated channels for 120 VAC or 120 VDC signals. It installs in a 1771 I/O chassis with a field wiring arm (Cat. No. 1771-WD) and isolates each input channel via opto-electrical isolation. In a control system, it converts field discrete input devices (e.g. float switches, limit switches, pushbuttons) to logic levels for PLC monitoring and control. Typical industrial applications include machine control, process monitoring, and discrete safety input interfacing. Part number 1771-ID.
Best Suited For
- PLC-5 based legacy discrete input integration
- Applications requiring individual channel isolation at 120 VAC/DC
- Signal interfacing for float, limit, selector or pushbutton switches
- Replacement in existing 1771 chassis systems
