BENTLY 125720-02 Relay Output Module
The module operates with an input current of 0.5 A and outputs a stable 24 V DC supply for downstream components.
The relay contacts are rated at 5 A / 250 VAC, and some versions support 10 A / 250 VAC or 10 A / 30 VDC switching capability, enabling reliable operation with moderate to high loads.
With a power consumption of less than 1 W, the module delivers excellent energy efficiency, effectively reducing long-term system operating costs.
Communication & Interface
Equipped with a standard RS-485 interface, the module supports the Modbus RTU protocol for easy integration with SCADA, PLC, and distributed control systems.
Additional sources indicate compatibility with CANopen, expanding its interoperability with a broader range of industrial automation platforms.
A DB9 connector ensures secure and convenient wiring, simplifying installation, commissioning, and maintenance.
Relay & I/O Configuration
The unit incorporates 8 built-in relays, providing multi-channel input/output capability for flexible system design. This configuration allows the module to adapt to different control architectures and environmental constraints while meeting diverse equipment switching requirements.
Environmental Adaptability
Designed for harsh industrial conditions, the module supports a wide operating temperature range of –40°C to +85°C, ensuring reliable performance in environments with extreme temperature, large temperature swings, high humidity, or airborne dust.
Core Functional Features
1. Relay-Based Switching Control
The module offers stable relay switching performance suitable for basic start/stop control, interlock control, or operational mode switching of industrial equipment.
With precise contact behavior and multi-channel design, it supports tasks ranging from simple on/off operations to more complex process sequencing and step-logic switching.
2. High Efficiency & Low Power Operation
The low-power architecture (<1 W) reduces system energy consumption without compromising control reliability.
Fast communication responsiveness minimizes command transmission delays, ensuring coordinated and smooth operation within larger automation systems.
3. Flexible Integration in Automation Systems
With RS-485/Modbus RTU and optional CANopen support, the module integrates seamlessly into a broad spectrum of automation systems.
Its multi-relay configuration makes it suitable as a signal conversion, execution, or auxiliary control component within distributed control architectures.
Application Scenarios
This module is widely used across industrial automation fields, including:
Production line linkage control and equipment interlocking
Auxiliary circuit switching for large machinery
Process control and signal actuation in generation plants, metallurgical facilities, and chemical industries
Any control scenario requiring high environmental tolerance and stable relay-based action
As a key node for signal output and execution, it enhances system reliability by enabling precise monitoring, deterministic switching behavior, and coordinated control across complex industrial systems.
