Allen-Bradley 1746-IA4 Digital Input Module

The AB 1746-IA4 is a digital input module designed for Allen-Bradley's SLC 500 programmable logic controllers (PLCs). It allows your PLC to read the on/off state of external digital devices. Specifications:Number of Input Channels: 4 channelsInput Type: AC Voltage (Alternating Current)Voltage Rating: 85 to 132 Volts AC (accepts a range of AC voltages within this limit)Current Draw: Low current consumption, typically around 0.27 Watts per channelResponse Time: Signal delay between input change and the PLC recognizing it, can be either 35 milliseconds or 45 milliseconds depending on the module revisionFeatures:Compact Design: Saves space in your control cabinetEasy Installation: Uses a standard SLC 500 backplane connectorLED Status Indicators: Provides visual indication of the state of each input channel (on/off)North American Hazardous Location Approved: This indicates the module meets specific safety standards for use in hazardous environments where flammable materials might be present
