The Allen-Bradley 1771-IEC is a PLC 5 analog input module designed to facilitate efficient communication between analog inputs and PLC processors through intelligent block transfer programming. With an 8-bit resolution, this module can handle up to eight single-ended inputs and accommodates voltage ranges from 1 to 10V DC and current ranges from 4 to 20mA. Essential for applications like temperature and pressure sensing, this unit offers protections such as optoelectrical isolation and input filtering to minimize electrical noise, and it includes LED indicators for status monitoring. Featuring a backplane current load of 400mA at 5V DC and a response time optimized for both AC and DC states, the module ensures reliable performance in demanding industrial environments. Additionally, its design allows for easy installation with a 1771-WB wiring arm and keying bands to ensure correct alignment in the chassis.
