The Allen-Bradley 1762-IF2OF2 is a MicroLogix 1200 I/O 4 Channel Analog Combo Module made for use controllers in industrial environments.
The 1762-IF2OF2 has integrated Four (4) analog channels in total which consists of Two (2) Input and Two (2) outputs, both configurable for Voltage or Current signals. The input channels support differential input while the outputs are single-ended outputs. Compatible signals for both input and output are 4 to 20 mA for Current while Voltage inputs are 0 to 10V.
Two differential unipolar inputs with a 2.5-ms update time and a common-mode input voltage range of +/-27 Volts, with 55 dB at 50 to 60 Hertz in common mode rejection. Its non-linearity is +/-0.12%, and overall accuracy is +/-0.55% full at -20 to 65 degrees Celsius and +/-0.3% at 25 degrees Celsius. The module has an input impedance of 250 Ohms at the terminal current and 200 kilo-Ohms at terminal voltage.
This module has features like input voltage protection of +/-30 Volts and input current protection of +/-32mA, and its BUS draw current is 40mA at 5 Volts DC and 105mA at 24 Volts DC. It has an analog operational voltage range between 0 and 10 Volts DC and 4 and 20 mA, which can reach a full-scale range of 0 to 10.5 Volts DC and 0 to 21 mA, and it has a 12-bit unipolar repeatability and resolution of +/-0.12%. This module measures approximately 3.54 x 3.43 x 1.58 inches and weighs about 0.53 pounds.
This module is installed beside the MicroLogix 1100 / 1200 / 1400 compact base and can be installed along the main controller base on a DIN Rail or directly to a mounting plate. It requires appropriate grounding to reduce noise that may affect the device’s operation. The module provides a cost-effective solution for incorporating a mixed of signal types and saves expansion and panel space.
The analog input circuitry of this module is provided with an analog to digital converter that converts the received analog signal to a binary coded register with 12-Bit unipolar resolution. Analog inputs may represent magnitude of process variables such as Flow, Level, Pressure, and Temperature. The analog output may be used to drive modulating devices such as a modulating control valve, variable frequency drive, dampers, louvers, and many other devices that move in a modulating style. It may also be used to re-transmit data for use of data loggers, indicators, recorders, and other receiving elements.
