FUNCTIONAL DESCRIPTION:
The 5441-689 PLC Relay Module is a high-density industrial switching interface designed for integration within Woodward MicroNet and MicroNet Plus control systems. It provides a reliable connection point between the system's digital control logic and a wide array of field-side Programmable Logic Controllers (PLCs) or auxiliary equipment. This module is engineered to expand the discrete output capabilities of the control chassis, offering high-speed switching for signal-level or power-level interconnections. Its robust design is specifically tailored to mitigate the effects of electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring clean signal transmission in noisy industrial power plants and engine rooms.
HIGH-DENSITY SIGNAL MANAGEMENT AND ISOLATION:
Featuring 16 independent relay channels, the Relay Module offers significant space efficiency for complex control architectures. Each channel provides a high degree of electrical isolation, preventing voltage transients from the field from damaging the internal backplane or processor modules. The module utilizes high-quality relays that act as a physical buffer, allowing the MicroNet system to trigger external PLC inputs or small solenoids without direct electrical coupling. This multi-channel density allows for comprehensive monitoring and control of auxiliary systems, such as fuel skids, cooling fans, and safety interlocks, from a single centralized interface.
SYSTEM INTEGRATION AND RELIABILITY:
The Relay Module is designed for seamless installation within standard MicroNet chassis, utilizing the high-speed VME bus for data communication. Its "hot-swappable" potential and rugged aluminum construction make it ideal for continuous-duty applications where system uptime is critical. The module includes integrated status LEDs for each of the 16 channels, providing immediate visual confirmation of relay states to onsite technicians. This diagnostic capability, combined with a wide operating temperature range, ensures the module remains a dependable link in the control chain even under extreme environmental stress.

What is the Woodward 5441-689?
It is a 16-channel PLC Relay Module used in MicroNet control systems. It provides high-density discrete switching, allowing the control system to interface with external PLCs or other industrial equipment through isolated relay contacts. It is designed to handle multiple signal paths simultaneously within a single chassis slot.
What is the primary use of the Woodward 5441-689?
This module is primarily used to provide isolated, discrete outputs from a Woodward MicroNet system to auxiliary control panels or PLC inputs. It is commonly found in complex turbine control systems where the main controller must coordinate with various peripheral subsystems. Its role is to ensure clear, isolated communication between different control platforms.
How many channels does the Relay Module have?
The module features 16 independent relay channels. This high density allows it to manage a large number of discrete signals without requiring multiple modules, which is particularly beneficial in systems with limited chassis space. Each channel is electrically separated to ensure maximum signal integrity and safety.
What is the relay contact rating for this module?
The relays on the Relay Module are typically rated for 5 Amps. While this is lower than some heavy-duty power relay modules, it is perfectly suited for interfacing with PLC inputs, small solenoids, and status lamps. If higher current switching is required, this module can be used to drive larger external interposing relays.
