3500/70 125720-01 Relay Module
Product Manual：
Product Overview
3500/70 125720-01 is a relay module of the 3500 series distributed control system (DCS), used to convert digital signals of the control system into relay switch actions, thereby controlling field equipment such as pumps, valves, indicator lights, or alarm devices.
This module provides a reliable digital output interface for the system and is a key unit for implementing on-site equipment execution control in DCS systems.
Main functions
Digital signal output: Convert the digital signal of PLC or controller into relay action.
Multi channel control: The module supports multiple independent channels and can simultaneously drive different actuators.
Security protection: Equipped with overcurrent and short-circuit protection to ensure the safety of modules and external devices.
Technical Features
Industrial grade relay components, suitable for high-frequency switching and harsh on-site environments.
Modular design facilitates installation, disassembly, and maintenance within the rack.
Supports full compatibility with 3500 series controllers and racks.
High reliability, suitable for continuous operation and frequent switching operations.
Can be combined with redundant systems to improve overall system reliability.
Application scenarios
Digital output control in industrial automation processes.
On site actuator control in industries such as chemical, power, petrochemical, and metallurgical.
Control the status of alarm devices and indicator lights.
Expansion of digital output interface in DCS system.
