MMS6350 | EPRO MMS 6350 Speed Measurement Card

Overview

The EPRO MMS 6350 Speed Measurement Card is a highly advanced speed measurement and protection system, specifically designed for monitoring and safeguarding rotating machinery from overspeed conditions. It is part of the DOPS (Dynamic Overspeed Protection System), ensuring maximum safety and reliability through its triple-channel architecture.

Key Features

Triple-Channel Design:
- Provides consistent signal detection, processing, and evaluation.
- Enhances safety by combining safety-relevant limits in a 2-out-of-3 logic.
Overspeed Protection:
- Measures and protects against inadmissible overspeeds.
- Operates in closed-circuit mode for high operational and protection standards.
Integrated Fault Detection:
- Continuously monitors speed sensors and output signals.
- Faults are displayed as plaintext on the front display and via output contacts.
Peak Value Memory:
- Stores the maximum speed value before the machine shuts down.
- Provides critical data for assessing mechanical loads during overspeed events.
Dynamic Outputs:
- Processes input pulses and outputs them as TTL pulses or via potential-free opto-couplers.
Flexible Configuration:
- Binary inputs and outputs allow for customized functions and alarms.
- Configurable using RS-232 or RS-485 communication interfaces.
Redundant Power Supply:
- Ensures reliable operation with two redundant +24 V inputs.
