The 1762-IF2OF2 is an expansion module that works with Allen-Bradley's MicroLogix 1100, 1200, and 1400 programmable Logix controllers (PLCS). The module is a combined analog I/O module that integrates a total of four (4) analog channels, including two (2) inputs and two (2) outputs, all configurable as voltage or current signals.

The input channel of the module supports differential input, while the output is single-ended output. The compatible signals for input and output are 4 to 20 mA, while the voltage input is 0 to 10V. The full range of inputs and outputs is 0 to 10.5Vdc and 0 to 21 mA. With 12-bit resolution. Repeatability was ±0.12%.

The module is mounted next to the MicroLogix 1100/1200/1400 compact base. The supplied ribbon cable connects to adjacent cables to establish a modular bus to provide module interconnection and distribution of bus voltage. It can be mounted on the DIN rail along the main controller base or directly on the mounting plate. Both installation methods require proper grounding to eliminate and reduce noise that can affect the operation of the equipment.

Due to the limited scalability of the MicroLogix controller product family, this expansion module provides a cost-effective solution by integrating multiple signal types and saving expansion and panel space.

The analog input circuit of the module is equipped with an analog-to-digital converter that converts the received analog signal into a binary-coded register with 12-bit unipolar resolution. Analog inputs can represent the magnitude of process variables, such as flow, level, pressure, and temperature.

Analog outputs can be used to drive modulation devices such as modulation control valves, variable frequency drivers, dampers, shutters, and many other devices that move in a modulated manner. It can also be used to retransmit data for use by data loggers, indicators, recorders and other receiving elements.
