Allen Bradley 1734-OW2 Detailed Technical Overview
1. Product Overview
The Allen Bradley 1734-OW2 is a 2-channel relay output module designed for distributed industrial automation systems. It uses electromechanical relay contacts to switch loads, making it suitable for both AC and DC applications where transistor-based outputs are not appropriate.
This module provides two independent normally open relay outputs, allowing it to control devices such as contactors, solenoid valves, alarms, and lighting circuits. Because it uses relay contacts, it offers inherent electrical isolation between the control system and the field devices, improving safety and compatibility.
Its compact DIN rail-mounted design makes it ideal for modular control panels, especially where space is limited and flexible I/O expansion is required.
2. Brand and Series
- Brand: Allen Bradley
- Series: 1734 Series
- Platform: POINT I/O
- Module Type: Relay Output Module
The POINT I/O system is built for distributed automation, allowing I/O modules to be installed closer to field devices. This reduces wiring complexity and improves system efficiency.
