Description

The Allen-Bradley 1756-OF8I is a high-performance isolated analog output module designed for the ControlLogix platform. This module provides eight channels of isolated analog output, supporting both current and voltage signals to meet diverse industrial control requirements. It is engineered to provide precise control for actuators, valves, and variable speed drives in demanding automation environments.

Features

Eight (8) isolated analog output channels.
Supports configurable current ranges (0-20 mA, 4-20 mA) and voltage ranges (-10 to 10V, 0 to 10V, 0 to 5V).
16-bit resolution for high-accuracy signal output.
Integrated open-circuit detection for current outputs and short-circuit detection for voltage outputs.
Overvoltage protection up to +/-30V DC.
Compatible with 1756-TBCH and 1756-TBS6H Removable Terminal Blocks (RTB).

Applications

The 1756-OF8I is widely utilized in industrial process control systems, including water treatment, chemical processing, and manufacturing automation. It is ideal for applications requiring galvanic isolation to prevent ground loops and ensure signal integrity between the controller and field devices.
