Epro MMS6350/DP Overspeed Measurement Board

Product Introduction

The Epro MMS6350/DP is a high-speed overspeed measurement board designed for precision rotation speed monitoring and protection in industrial machinery. As part of Epro’s MMS6000 series, this module provides reliable detection of excessive rotational velocity, ensuring machinery safety and preventing catastrophic failures due to overspeed conditions.

Featuring dual-channel inputs for redundancy and real-time processing, the MMS6350/DP converts incremental or analog speed signals into digital data that can be used by control systems or safety relays. The board’s compact form factor, rugged construction, and integrated filtering circuitry make it suitable for both new installations and retrofit projects.

Engineered to meet stringent safety standards, the MMS6350/DP incorporates galvanic isolation between input channels and the processing circuitry, minimizing the risk of false trips caused by noise or signal interference. Integrated diagnostics continuously monitor input signal integrity and board health status, providing diagnostic outputs to higher-level controllers or HMI displays.

With dimensions of 31 × 190 × 129 mm and a weight of only 0.20 kg, the MMS6350/DP occupies minimal panel space while delivering robust performance. Its wide operating temperature range and conformal-coated electronics ensure reliable operation in harsh industrial environments such as power generation, turbines, compressors, and manufacturing lines.

Technical Specifications

Product Applications

The Epro MMS6350/DP is ideal for critical overspeed monitoring in a variety of industrial applications.

In gas and steam turbines, the module detects rapid increases in shaft speed, enabling immediate shutdown to prevent mechanical damage.

Within compressor systems—both centrifugal and reciprocating—the board ensures safe operation during startup, shutdown, and load transitions.

In wind turbines, the MMS6350/DP provides redundant speed sensing to trigger braking systems and pitch controls when high wind conditions risk rotor overspeed.

The board also finds use in industrial pumps, generators, and large motors where overspeed conditions can arise due to mechanical faults or control failures.

By interfacing with PLCs, DCS, or dedicated safety relays, the module offers reliable overspeed protection for rotating equipment in petrochemical, power generation, oil & gas, and manufacturing sectors.

Product Advantages

High-speed sampling: The 1 ms sampling rate captures rapid changes in rotational velocity, ensuring early detection of overspeed conditions.

Dual-channel redundancy: Two independent input channels allow cross-checking of speed signals, reducing false trips and enhancing system reliability.

Flexible signal input: Supports both differential TTL/RS-422 pulses from incremental encoders and 4–20 mA analog inputs for proximity probes, enabling compatibility with a wide range of sensors.

Robust isolation: 1,500 V RMS isolation between inputs and the board’s power supply protects against ground loops and electrical noise, delivering stable measurements in electrically noisy environments.

Compact and lightweight: At 31 × 190 × 129 mm and 0.20 kg, the MMS6350/DP occupies minimal panel space, facilitating installation in control cabinets and retrofit panels.

Conformal-coated circuitry: Provides resistance to moisture, dust, and vibration, ensuring longevity and fewer maintenance interventions.

Safety certifications: CE and UL 508 listings, along with SIL 2 capability, allow integration into safety instrumented systems (SIS) for machinery protection.

Easy integration: Standard 24 VDC power, TTL-compatible outputs, and diagnostic flags simplify interfacing with PLC, DCS, SCADA, and safety relays.
