Discrete Output Module Allen-Bradley 1746-OB16E SLC 500 24V DC

Product Overview

The Allen-Bradley 1746-OB16E is a digital output module for the SLC 500 series. It provides 16 source outputs. It operates on 24V DC power. The module uses electronic fusing for protection. It fits into any slot in a 1746 chassis. The module uses a Removable Terminal Block (RTB). This makes wiring simple and fast. The 1746-OB16E draws 0.135A from the backplane at 5V DC. It has a signal delay of 1ms for ON and OFF. The module has a maximum output current leakage of 1mA. It supports high current applications.

Application Scenarios

This module is ideal for industrial automation. It controls actuators, valves, and relays. It works well in factory assembly lines. It is suitable for packaging machines. It can control conveyor systems. It is used in material handling equipment. The module works in harsh environments. It operates from 0 to 60 degrees Celsius. It has a 30G shock rating. It is NEMA ICS 2-230 rated for noise immunity.

Technical Specifications

The module has 16 output points. Each point can handle 1 or 0.5 amps. The total module current is 8 amps. At 30 degrees Celsius, it can handle 9 amps. The voltage range is 10 to 30 Volts DC. The inrush current is 2.0A per point. This lasts for 2ms each second. The module dissipates 0.388W per point. Total heat dissipation is 7.6W. The step response is 60ms in and 2.5ms out. The module weighs about 0.3 kg.

Installation & Maintenance Guide

Install the module in any 1746 chassis slot. Ensure the chassis power is off. Align the module with the backplane connector. Press firmly until it clicks. Secure the module with screws. Wire the field devices to the RTB. Use 10 to 30V DC source power. Do not exceed the current ratings. Keep the module in a clean, dry area. Check for loose connections regularly. Replace the module if the fuse blows repeatedly.
