Allen-Bradley 1771-ID16 | PLC 5 Digital AC/DC Input Module

Overview

The 1771-ID16 from Allen-Bradley is a versatile Digital AC/DC Input Module for PLC 5 processors. It supports 16 isolated inputs capable of handling both AC and DC voltage. The module features customer-selectable input filtering to suppress contact bounce and electrical noise. This ensures high power quality, reduces downtime, and extends product lifespan.

Connections are made through the 1771-WN wiring arm, allowing removal or insertion without disconnecting field wires. The 1771-ID16 works seamlessly with 1771-A1B, 1771-A4B, or later I/O chassis. It is ideal for float switches, selector switches, limit switches, and pushbuttons in isolated-circuit applications.
