PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-IQ is a PLC-5 digital input module providing eight discrete DC input circuits. It operates within a DC voltage range between 5 and 30 Volts DC. The module falls into the sink or source load voltage category of 10 to 60 Volts DC. It connects to the PLC-5 system backplane and draws 150 milliamperes of backplane current. The module mounts directly into an Allen-Bradley Bulletin 1771 chassis.
This input module supports high-speed signal processing with selectable response rates. It delivers a fast on and off signal delay of less than 1 millisecond. The slow delay setting provides a nominal response of 12 milliseconds. Field wiring connects via dedicated Bulletin 1771 wiring arms such as the 1771-WH and 1771-WC. Engineers can install the module in any single chassis slot except the leftmost slot.
