Epro MMS6312 Dual Channel Rotational Speed Monitor

Epro MMS6312 Key parameters

Modular Integration & System Compatibility

The MMS6312 is designed for seamless integration into the EPRO MMS 6000 System and IMR 6000 series racks (12TE width). Occupying 2 slots in a 3U-sized frame, it supports hot-swappable installation for maintenance without downtime . Its compact footprint (100 × 160 × 30 mm) reduces cabinet space by ~50% compared to legacy modules, while maintaining compatibility with redundant sensor inputs and power supplies .

Processing & Communication Architecture

Core Processor: Utilizes a 32-bit ARM Cortex-A9 processor operating at 1 GHz, paired with 1 GB RAM and 128 MB flash memory for real-time data processing and logic execution .

I/O Configuration: Features 32 digital inputs, 32 digital outputs, 8 analog inputs, and 2 analog outputs for multi-sensor integration .

Protocol Support: Includes EtherCAT, Profinet, and Modbus TCP/IP for interoperability with industrial automation systems, alongside RS-485 for communication with EPRO’s MMS 6850 Diagnostic Suite .

Sensor Input Dynamics

Compatibility: Works with eddy-current probes (e.g., PR 6422/PR 6425, PR 9376) and pulse sensors (PR 6453), offering ±27.3 VDC excitation voltage per channel .

Frequency Range: Configurable up to 20 kHz, translating to 65,535 RPM for high-speed rotational monitoring .

Self-Testing: Integrated diagnostics verify sensor integrity, cable faults, and signal continuity, triggering pre-alerts via front-panel LEDs .

Power & Environmental Resilience

Redundant Power Inputs: Dual 18–31.2 V DC supplies with diode decoupling ensure uninterrupted operation under voltage fluctuations .

Power Consumption: ≤6 W under full load, compliant with IEC 654-2 Class DC4 .

Temperature Range: Operates at 0°C to 65°C and withstands storage/transport conditions of -40°C to 70°C .

Vibration Resistance: Endures 20 m/s² (55–150 Hz) vibrations and 98 m/s² mechanical shocks per IEC 68-2 standards .
