PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-IA4 is a 4-channel digital AC input module for the SLC 500 platform. This module operates with an input voltage range between 85 and 132 Volts AC at 47 to 63 Hertz. It provides four discrete AC inputs designed for general-purpose automation interfacing in a single chassis slot. Nominal input current is 12 milliamps at 129 Volts AC.
The unit draws 35 milliamps of backplane current at 5 Volts DC and 0 milliamps at 24 Volts DC. Signal delay times specify a maximum of 35 milliseconds for turn-on and 45 milliseconds for turn-off. The maximum off-state current is 2 milliamps, with a maximum off-state voltage rating of 30 Volts AC. It features an open-style enclosure, built-in status displays, and operates from 32 to 140 degrees Fahrenheit.
