Allen-Bradley 1756-OF4 Analog Output Module ControlLogix

Product Overview

The Allen-Bradley 1756-OF4 is a reliable analog output module for the ControlLogix platform. This module provides four configurable output channels. Each channel supports voltage or current signals. It delivers precise control for industrial automation tasks. The module uses a 15-bit resolution for voltage outputs. It also offers 15-bit resolution for current outputs. This ensures accurate signal generation for your processes. The module fits seamlessly into a ControlLogix chassis. It communicates directly with the backplane. The 1756-OF4 is a key component for many industrial systems.

Application Scenarios

This module works well in various industrial settings. Use it for process control in manufacturing plants. It can control valves, actuators, and drives. The module is ideal for batch processing applications. It also suits continuous production lines. Use it in oil and gas facilities. It works in water treatment plants. The module handles chemical processing tasks. It is also useful for power generation. The 1756-OF4 provides stable outputs in harsh environments. It operates reliably in temperatures up to 60 degrees Celsius.

Technical Specifications

The module has four output channels. You can set each channel for voltage or current. The voltage range is plus or minus 10 volts. The current range is 4 to 20 milliamps. Voltage resolution is 15 bits across 10.5 volts. This equals 320 microvolts per bit. Current resolution is 15 bits across 21 milliamps. This equals 650 nanoamps per bit. The module draws 150 milliamps from the 5-volt backplane. It draws 120 milliamps from the 24-volt backplane. Maximum power dissipation is 4.9 watts. Isolation voltage is 50 volts continuous. Use the 1756-TBNH or 1756-TBSH terminal blocks.

Installation & Maintenance Guide

Install the module into any ControlLogix slot. Ensure the chassis power is off first. Slide the module into the slot until it locks. Connect the terminal block to the module. Use the correct wiring for your output type. For voltage outputs, use shielded cables. For current outputs, use twisted pair wires. Secure all connections tightly. Check the module status indicators after power-up. Perform regular inspections for dust or damage. Keep the module in a clean environment. Replace the module only with the same model.

Packing List
