Discrete Output Module Allen-Bradley 1746-OW8 SLC 500 Relay

Product Overview

The Allen-Bradley 1746-OW8 is a digital contact output module. It belongs to the SLC 500 series. This module offers 8 normally open relay contacts. It works with both AC and DC voltages. The operating range is 5 to 265 Volt AC. It also works with 5 to 125 Volt DC. This makes it very flexible for different applications. Each output can handle up to 1.5 amps at 120 VAC. It can handle 1.2 amps at 24 VDC. The module has two groups of outputs. Each group has four points. This design helps with wiring and isolation. The 1746-OW8 is a single slot module. It is easy to install in any SLC 500 chassis.

Application Scenarios

This module is ideal for controlling industrial loads. Use it to switch motors, solenoids, and lights. It works well in factory automation. It is also good for process control systems. The relay outputs provide electrical isolation. This protects the PLC from high voltage spikes. Use it in packaging machines. Use it in material handling systems. It is also common in HVAC controls. The module can switch both AC and DC loads. This reduces the need for separate modules. It works in harsh industrial environments. The operating temperature range is wide. It runs from -25 to 60 degrees Celsius.

Technical Specifications

The 1746-OW8 has a step response of 60 milliseconds in. The off response is 2.5 milliseconds. The backplane current is 0.85 to 0.9 A. It draws 85 mA at 5V DC. It draws 90 mA at 24V DC. The signal delay is 10.0 ms for both on and off. The module dissipates 3.7 Watts of heat. Each point adds 0.138 Watts. It can withstand 2g of vibration. It can handle 30g of shock. The enclosure type is open equipment. The pollution level is 2. It has Class 1, Division 2 certification. The continuous current per module is 16.0 Ampere AC. Each group can handle 8.0 A.

Installation & Maintenance Guide

Install the module into any single slot. Use the keying feature to prevent damage. Wire the outputs according to the manual. Use proper wire sizes for the current. Keep the module within the temperature range. Ensure good airflow around the module. Do not exceed the group current limits. Use a separate fuse for each group. Check the wiring for tight connections. Replace the module only when power is off. Clean the module with a dry cloth. Do not use solvents.
