• Dimensions: Measures 11.1 cm in height, 27.889 cm in width, and 35.789 cm in length, with a weight of 0.953 kg.

Applications

The 1771-IFE module is ideal for process measurement applications such as temperature, pressure, level, flow, pH, viscosity, and vibration. It effectively converts various process variable signals into proportional PLC data values, facilitating accurate monitoring and control.

Installation and Configuration

Designed for seamless integration into any 1771 I/O chassis, the module occupies a single slot and requires no external power supply. Configuration options include:

• Input Type Selection: Each channel can be configured for voltage or current input using internal jumpers.
• Input Range Selection: User-programmable input ranges on a per-channel basis, accommodating diverse application requirements.
• Data Formatting: Selectable data formats and scaling options to suit specific processing needs.

The module’s front panel features a green RUN indicator and a red FAULT indicator. Upon power-up, a self-check occurs; if no faults are detected, the red indicator turns off, and the green indicator flashes until successful communication with the processor is established.
