1794-OE4XT Allen-Bradley Flex I/O Analog Output Module

Product Overview

The Allen Bradley 1794-OE4XT is a high-density analog output module. It belongs to the Flex I/O 1794 series. This module provides four single-ended outputs. These outputs are non-isolated. It works under extended temperature conditions. This makes it suitable for harsh environments. The device supports both voltage and current outputs. Voltage range is -10 to 10V. Current range is 0 to 20 mA. It handles resistive loads from 15 to 750 ohms at 24V DC. The module needs an external 24V DC power supply. The input range is 19.2V DC to 31.2V DC. This flexibility ensures easy system integration.

Application Scenarios

Use this module in industrial automation systems. It works well for process control applications. It can control actuators, valves, and transmitters. The extended temperature rating allows use in outdoor cabinets. It fits into oil and gas, chemical, and manufacturing plants. The module integrates with PLCs and DCS systems. It sends precise analog signals to field devices. This ensures accurate process regulation.
