5441-689 Relay Module Woodward PLC Interface for Motors & Valves

Description

The Woodward 5441-689 PLC Relay Module is engineered to provide precise switching and control of electrical loads such as motors, valves, and solenoids. It is part of Woodward’s modular control system architecture, supporting flexible integration with PLCs, DCS platforms, and supervisory systems. This module includes both digital input and output capabilities. It converts TTL-level signals into industrial-grade relay outputs, ensuring compatibility with actuators and field devices. Moreover, it supports RS-232 and RS-485 serial communication and is fully compliant with Modbus RTU protocol, enabling seamless data exchange with host controllers. In addition to its hardware features, the 5441-689 supports user-defined control logic via ladder diagrams or structured text programming. Its internal diagnostics and fault monitoring functions enhance system reliability and simplify troubleshooting. Therefore, this module is widely used in power generation, process control, and heavy manufacturing environments where robust relay control and system interoperability are essential.
