Allen-Bradley 1756-OB16EK ControlLogix 16-Point DC Output Module

Product Overview

The Allen-Bradley 1756-OB16EK is a ControlLogix electronic fused output module. It features 16 DC outputs. Each point delivers up to 1 Amp. The module operates on 10-31.2V DC power. It uses a 20-pin removable terminal block. This design simplifies wiring and maintenance. The conformally coated version offers extra protection. It resists moisture and contamination. This module is ideal for high-availability systems.

Application Scenarios

This module suits many industrial control tasks. Use it for machine control in factories. It works well for conveyor systems. It can drive DC solenoids and valves. The electronic fusing protects connected devices. This makes it perfect for critical processes. It fits into any ControlLogix chassis. Use it in discrete manufacturing or process control. It also works in material handling systems. The robust design handles harsh environments.

Technical Specifications

The 1756-OB16EK has 16 electronically fused outputs. The voltage category is 12/24V DC source. Operating voltage ranges from 10 to 31.2V DC. Maximum current per point is 1 Amp at 60°C. Total module current is 8 Amps at 60°C. Power dissipation is 4.1 Watts at 60°C. It draws 250 milliamps from the 5V backplane. Isolation voltage is 50 Volts continuous. It requires a 1756-TBNH or 1756-TBSH terminal block.

Installation & Maintenance Guide

Install the module into any ControlLogix chassis. Use the 1756-TBNH or 1756-TBSH terminal block. Wire outputs according to your system diagram. Ensure power is off before installation. The electronic fusing eliminates the need for external fuses. This reduces maintenance time. Regularly check the module status via the LED indicators. Keep the enclosure clean and dry. The conformal coating helps prevent corrosion.
