16-Channel Relay Output Module | 1751-6091 Woodward

Product Overview

The Woodward 1751-6091 functions as a high-density, 16-channel relay interface module specifically engineered for the 505 and 505E digital turbine control series. This hardware executes independent switching commands for critical auxiliary systems, including fuel pumps, cooling fans, and solenoid valves. By providing galvanically isolated digital outputs, the 1751-6091 protects sensitive controller logic from field-side electrical surges and noise. It serves as a fundamental component in steam and gas turbine governing systems, ensuring deterministic sequencing and high-availability operation in safety-critical industrial environments.

Technical Specifications

Engineering Advantages

The 1751-6091 addresses the complex interfacing requirements of modern power plants and mechanical drive systems. Its design delivers several distinct engineering benefits:

• High-Density Integration: The 16-channel architecture significantly reduces cabinet footprint, allowing engineers to manage complex auxiliary sequencing within a single module.

• Network Transparency: Integrated Modbus support via RS-232/RS-422 ensures the module feeds real-time relay status back to the DCS, facilitating advanced diagnostics and remote monitoring.

• Electrical Noise Suppression: Industrial-grade galvanic isolation prevents field-induced interference from disrupting turbine control logic, a common issue in high-power motor environments.

• Software Synchronization: Full compatibility with Woodward 505View™ enables rapid configuration and calibration of relay trip points, reducing commissioning time for steam and gas turbine start-up sequences.

FAQs

• Is this Woodward 1751-6091 unit 100% Brand New? Yes. We supply the 1751-6091 in 100% Brand New and Original condition, complete with original factory packaging to ensure peak reliability for safety-critical applications.

• Does this module support both AC and DC switching? The 1751-6091 handles standard industrial AC and DC load ranges. You must verify that your specific solenoid or auxiliary equipment current draw falls within the Woodward-defined relay contact ratings to prevent premature contact wear.

• Can I use this module with third-party PLC systems? While designed primarily for the Woodward 505/505E series, the module's support for Modbus protocol allows for communication with various industrial networks, provided the master controller supports the Woodward register mapping.

• What is the typical lead time for this part? We maintain the 1751-6091 In Stock at our Xiamen port facility, allowing for a standard lead time of 2-3 working days for international shipment.
