5437-1124 Woodward Overspeed Protection Device

Product Overview

The 5437-1124 Woodward overspeed protection device delivers reliable speed monitoring and shutdown for turbines and rotating machinery. This compact unit accepts MPU or proximity probe inputs up to 100 kHz, providing 4-20 mA proportional output and dual relay contacts for trip and alarm functions. Engineered for demanding industrial environments, the 5437-1124 operates from -40 to 85 °C.

Core Advantages

Wide 24V dc supply range (18-32V). Dual independent setpoints for alarm and trip. Adjustable time delays from 0.1 to 10 seconds. LED status indicators for power, speed, and relay states. DIN-rail or panel mounting options. Reverse polarity and transient protection.

Technical Specifications

Installation Quick Notes

Wiring: Use shielded twisted pair for MPU input; keep separate from power cables. Grounding: Single-point ground to avoid ground loops. Setpoint adjustment: Use front-panel trimpots or remote potentiometer (1k to 10k ohm). Mounting: DIN-rail (35mm) or direct panel mount with M4 screws.

Why Choose 5437-1124

Compact and cost-effective overspeed solution. Wide input frequency range supports most speed sensors. Independent trip and alarm relays enable tiered protection strategy. IP65 rating allows installation in washdown areas. Field-adjustable time delays prevent nuisance trips during transient overspeed events.

FAQs

Q1: What sensor types are compatible with the 5437-1124?
A1: Magnetic pickups (MPU) with 50 mV to 30V output, and proximity probes with NPN or PNP signals.

Q2: How do I set the trip point?
A2: Use the front-panel Setpoint 1 and Setpoint 2 trimpots. Each scales from 0 to 100% of the configured full-scale frequency.

Q3: Can the 4-20 mA output be scaled for different speed ranges?
A3: Yes. Adjust the zero and span potentiometers to map the input frequency to any 4-20 mA range within 0-100 kHz.
