1771-IE04

The Allen-Bradley 1771-IE04 is a PLC 5 Analog Input Module. It is an intelligent module that interfaces with analog inputs and PLC processors using block transfer programming. It uses up to 8-bit resolution and performs the required analog to digital conversions and vice versa to interface analog signals with PLC data table values. It has various applications such as temperature and pressure sensing, level sensing, and flow metering. The 1771-IE04 Series B module has 8 single-ended inputs. It has a voltage range of 0 – 10V DC and a maximum Off-state AC/DC current of 1.7mA and backplane current load of 400mA at 5V DC. It has a typical signal delay of 24ms (±10) at on/off AC state, 10ms (±4) at on DC state, and 20ms (±9) at off DC state. It comes with a 1771-WB wiring arm to replace the module, eliminating the need to disconnect wiring. It requires one slot for installation in an I/O chassis and keying bands for correct installation is between pins 4 and 6 for the lower connector and between pins 26 and 28 for the upper connector. The 1771-IE04 module contains a green RUN and a red FAULT indicator for fault and power status at the front panel. It contains optoelectrical isolation to protect the system circuits from electrical transients. It also contains an input filtering feature to reduce electrical noise.
