Speed Relay (SR) - Underspeed Relay Contact for Rotation Monitoring

Product catalog summary

Product Overview
The SR series speed relay by 4B Components Limited is designed for monitoring the speed of rotating shafts, ensuring they remain within a preset safety level. It is compatible with Rotech encoders and 4B’s WDA or P800 proximity sensors.

Application
The speed relay is used to detect underspeed conditions, triggering an alarm or machinery shutdown if the shaft speed falls below the preset level.

Features

Standard speed ranges available: 0 to 10, 100, and 1,000 RPM.
Single output relay with single pole changeover.
LED indicators for power and status.
Dual power supply options: 110/240 VAC.
Selectable 10-second start delay (SR1 only).
Opto-isolated input signal repeat output (SR1 only).

Technical Specifications

Supply voltage: 110/240 VAC.
Start delay: Built-in for SR1, optional for SR2.
Protection rating: IP50.
