Product Overview

The Woodward 1751-6091 is a high-density 16-channel relay interface module designed for industrial automation and engine control systems. It provides independent on/off switching for auxiliary equipment such as fuel pumps, cooling fans, and solenoid valves. Supplied 100% brand new and original, it ensures reliable sequencing, electrical isolation, and long-term operational durability in critical applications.

Technical Specifications

Engineering Advantages

High-Density Load Management
Consolidates 16 relay channels into a compact module, reducing cabinet space, wiring complexity, and installation effort while supporting complex sequencing tasks.

Deterministic Interface Logic
Acts as an electrical buffer between control electronics and field devices, protecting the CPU from back-EMF and transient voltages while ensuring reliable signal translation.

Superior Contact Stability
Uses industrial-grade relay contacts designed for high durability and low resistance, maintaining consistent switching performance across millions of cycles, even under inductive loads.

Simplified Field Integration
Supports independent channels with flexible load types, enabling mixed-voltage control (AC/DC) on a single module without additional interposing relays.

Rugged Industrial Design
Built with vibration-resistant construction suitable for harsh environments such as power plants and engine rooms, ensuring stable operation under mechanical stress.

FAQs

Can it directly drive large motors?
No. It is intended for control-level switching and should be used to trigger motor starters or contactors for high-power loads.

Does it provide feedback for each relay?
No direct load feedback is provided. A separate discrete input module is recommended to verify external device status.

Can a single failed relay channel be repaired?
Due to its integrated design, the entire module is typically replaced to maintain consistent reliability across all channels.

Is this a refurbished unit?
No. All units are 100% brand new, supplied in original Woodward factory-sealed packaging with full documentation and traceability.
