Allen Bradley 1734-OB8 Detailed Technical Overview
1. Product Overview
The Allen Bradley 1734-OB8 is an 8-channel digital DC output module designed for distributed industrial control systems. It is used to convert control signals from a controller into physical output actions, enabling field devices to operate in response to automation logic.
This module provides eight independent 24V DC sourcing outputs, making it suitable for controlling multiple devices simultaneously. Typical loads include relays, solenoid valves, pilot lights, and other DC-operated actuators.
Its compact and modular structure allows it to be installed inside control cabinets using DIN rail mounting, and it fits naturally into distributed I/O architectures where space efficiency and flexibility are important.
2. Brand and Series
- Brand: Allen Bradley
- Series: 1734 Series
- Platform: POINT I/O
- Module Type: Digital DC Output Module
The POINT I/O platform is built for decentralized control systems, allowing I/O modules to be placed closer to field devices. This reduces wiring length, simplifies installation, and improves system response time.
