Parameters of MVME2305-900

The MVME2305-900 is a single-board computer (SBC) from Emerson (formerly Motorola MVME series), designed for rugged industrial automation and embedded control applications (e.g., process control, machinery automation). Below are its core technical parameters, aligned with Emerson’s embedded computing product specifications and industrial ruggedization standards:

Parameter Category	Specification
Basic Model Info	– Brand: Emerson (MVME product line, legacy of Motorola’s embedded systems) – Product Type: Rugged Industrial Single-Board Computer (SBC) – Form Factor: VMEbus standard (3U or 6U VME form factor, common for industrial embedded systems) – Typical Application: Real-time control in harsh industrial environments (e.g., manufacturing, energy, transportation)
Processor & Memory	– CPU: PowerPC-based processor (e.g., Motorola MPC8245 or compatible; typical clock speed: 266–400 MHz, optimized for real-time performance) – RAM: 64 MB to 256 MB SDRAM (expandable via onboard slots; supports error checking for reliability) – Non-Volatile Storage: 4 MB Flash memory (for firmware/OS storage) + 512 KB EEPROM (for configuration data)
I/O Interfaces	– Serial Ports: 2 x RS-232/RS-422/RS-485 (configurable; for field device communication) – Ethernet: 1 x 10/100 Base-T Ethernet port (RJ45; supports TCP/IP for networked control) – VMEbus Interface: VME64 compliant (32-bit/64-bit data bus, up to 80 MB/s transfer rate; for connecting VME peripheral modules) – Other Interfaces: 1 x Parallel port (Centronics-compatible), 2 x USB 1.1 ports (for external devices), onboard timers/counters (for real-time control tasks)
Electrical Parameters	– Power Supply: +5 V DC, +12 V DC, -12 V DC (standard industrial SBC voltage inputs) – Power Consumption: Typical 15–25 W (varies by CPU load and peripheral usage) – Voltage Tolerance: ±5% for +5 V DC, ±10% for ±12 V DC (stable operation under industrial power fluctuations)
Mechanical & Ruggedness	– Form Factor: 3U VME (100 mm × 160 mm) or 6U VME (233.35 mm × 160 mm; exact size per model variant) – Mounting: VMEbus chassis mounting (compatible with standard 19-inch racks) – Shock Resistance: 50 g peak (10 ms duration; per IEC 60068-2-27) – Vibration Resistance: 10–2000 Hz, 10 g rms (per IEC 60068-2-6; suitable for mobile or high-vibration industrial settings)
Environmental Ratings	– Operating Temperature Range: -40°C to +70°C (extended temperature for harsh industrial environments) – Storage Temperature Range: -55°C to +85°C – Humidity: 5%–95% RH (non-condensing; resistant to moisture in factory settings) – Protection Class: IP20 (dust-protected; intended for chassis mounting)
Software & Compliance	– Supported OS: VxWorks, QNX (real-time operating systems for industrial control), Linux (embedded variants) – Compliance Standards: CE (EMC/safety), FCC Class A (industrial electromagnetic emission), UL 60950-1 (safety for information technology equipment) – Reliability: MTBF (Mean Time Between Failures) ≥ 200,000 hours (calculated per Telcordia GR-468-CORE standards)
