1771-IEC

Need a Specific Revision?

The 1771-IEC input module is a PLC 5 series input module from Allen-Bradley/Rockwell Automation. This input module is an analog type of input module with 8 input channels. The 1771-IEC analog input module uses block transfer programming to interface between analog inputs and PLC processors. This 8-bit input module only needs 1 slot in a chassis for installation. The 1771-IEC analog input module can perform analog to digital data conversions and digital to analog data conversions.

The Allen-Bradley 1771-IEC is a PLC 5 Analog Input Module. It is an earlier model of the 1771-IE module with the same specifications. It is an intelligent module that interfaces between 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 between analog signals and the PLC data table values. It has various applications such as temperature and pressure sensing, level sensing, and flow metering. The 1771-IEC Series B module has 8 single-ended inputs. It has a voltage range of 1 – 5V DC, 0 – 5V DC, 0 – 10V DC and -10 – 5V DC. It has a current range of 4 – 20mA, 0 – 20mA and -20 – 20mA. It has 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-IEC module contains a green RUN and a red FAULT indicator lights om 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.
