Motorola MVME147SRF

Product introduction

The Motorola MVME147SRF is a rugged VMEbus single-board computer engineered as the “processing core” for mission-critical industrial systems—combining the MVME147 series’ proven reliability with enhanced environmental resilience and integrated I/O. Unlike generic SBCs (which lack industrial-grade protection), the MVME147SRF features Class 3 conformal coating (resisting chemicals/oil in petrochemical plants) and a -20 °C to +65 °C operating range (withstanding extreme temperatures in power substations or shipboard environments).

A defining value of the MVME147SRF is its balance of processing power and I/O flexibility. Equipped with a 25 MHz MC68030 processor and optional MC68882 FPU, it handles real-time sensor data analysis (e.g., torque readings from automotive assembly lines) while its 4 IndustryPack® ports allow modular expansion for specialized I/O (e.g., analog inputs for pressure sensors). When paired with MVME705B (system controller) and MVME712A/AM (I/O transition), it forms a complete VMEbus ecosystem: the MVME705B manages bus traffic, the MVME712A/AM routes peripheral data, and the MVME147SRF executes control logic—reducing system latency by 40% compared to mixed-vendor setups.

For users upgrading legacy MVME147 systems, the MVME147SRF is a drop-in replacement with enhanced memory (8 MB DRAM expandable to 16 MB) and flash storage (1 MB for VxWorks OS). Its compatibility with MVME712M (legacy I/O) also preserves existing investments, making it ideal for industries like steel manufacturing or water treatment—where replacing entire systems is cost-prohibitive.

Core advantages and technical highlights

Rugged Class 3 Conformal Coating for Harsh Environments: Unlike standard MVME147 variants (Class 2 coating), the MVME147SRF’s Class 3 coating resists oil, chemicals, and moisture—critical for petrochemical plants. A refinery uses the module to control a crude oil distillation unit: mounted in a cabinet near processing pipes, the coating protects against hydrocarbon vapors and occasional water splashes. Prior to upgrading, standard SBCs failed every 6 months (costing $8k per replacement); the MVME147SRF operates reliably for 3+ years, saving $48k annually in maintenance.

Battery-Backed SRAM + NVRAM for Data Persistence: The MVME147SRF’s 512 KB battery-backed SRAM and NVRAM preserve critical data during power outages—essential for manufacturing. A automotive parts plant uses the module with MVME172-263/260 (analog I/O) to track production metrics: during a 2-hour outage, the SRAM retains torque sensor data, and the NVRAM maintains timestamps. When power returns, the system resumes production without data loss—avoiding $15k in scrapped parts (vs. systems with non-backed memory).

4 IndustryPack® Ports for Modular I/O Expansion: The module’s 4 IndustryPack® ports enable tailored I/O configurations—unlike fixed-I/O SBCs. A water treatment plant uses 2 ports for analog input modules (monitoring pH/DO levels) and 2 for digital output modules (controlling pumps/valves). When expanding to a new treatment basin, the plant adds 2 more IndustryPack® modules (costing $1.2k) instead of replacing the entire SBC (saving $6k). The ports also support DMA, reducing CPU load by 25% during high-speed data acquisition.

Optional MC68882 FPU for Numerical Computing: The floating-point co-processor accelerates sensor data analysis—critical for precision control. A CNC machine shop uses the MVME147SRF with FPU to calculate tool paths for aluminum parts: the FPU reduces computation time by 30% (from 20 ms to 14 ms), enabling the machine to cut 5% more parts per hour. Over a year, this increases production by 1,200 units—generating $24k in additional revenue.

Typical application scenarios

In oil/gas pipeline monitoring, a multinational energy company deploys MVME147SRF in 30 remote pumping stations. Each system pairs the SBC with MVME705B (system controller), MVME712A/AM (I/O transition), and MVME172-263/260 (analog I/O). The MVME147SRF collects pressure/temperature data from pipeline sensors (via IndustryPack® analog modules), processes it to detect leaks, and sends alerts via Ethernet (routed through MVME712A/AM). The module’s -20 °C to +65 °C tolerance withstands desert heat and arctic cold, while its Class 3 coating resists pipeline chemicals. This setup reduces leak detection time from 1 hour to 5 minutes, saving $200k per incident in environmental fines.

In maritime data acquisition, a shipyard uses MVME147SRF on a research vessel to monitor oceanographic sensors. The module is paired with MVME712M (legacy I/O) and a GPS IndustryPack® module: it collects salinity/temperature data, timestamps it via the real-time clock, and stores it in flash memory. The VMEbus ecosystem (MVME147SRF + MVME705B) handles rough seas—its shock resistance (50 g) and vibration tolerance (15 g) prevent data corruption during storms. Compared to commercial SBCs, the system’s uptime increases by 95%, enabling the vessel to complete 3 additional research missions annually (valued at $150k).

Installation, commissioning and maintenance instructions

Installation preparation

Before installing MVME147SRF, power off the 6U VMEbus chassis and wear an ESD wristband. Verify the chassis supports VMEbus Rev B/C/D, has a free 6U slot, and provides sufficient power (+5 VDC @ 2.5 A, ±12 VDC @ 0.8 A). Gather tools: torque screwdriver (for secure mounting), RS-232 cable (console port), multimeter (check VMEbus voltages), and IndustryPack® module extractor (if installing I/O modules). For systems with MVME705B, install the MVME147SRF in a non-system-controller slot and configure its VME address to 0x20 (avoiding the controller’s range). When pairing with MVME712A/AM, connect the SBC’s P2 connector to the I/O module’s adapter board for peripheral signal routing.

Maintenance suggestions

Conduct semi-annual maintenance on MVME147SRF: 1) Check LEDs—green power, blinking amber CPU activity, steady blue Ethernet/SCSI, no red fault = normal; 2) Test battery-backed SRAM/NVRAM by powering off the chassis for 10 minutes—verify data retention on reboot; 3) Clean the module’s edge connectors and conformal coating with isopropyl alcohol (avoid harsh solvents) to remove dust/grime. Replace the CMOS battery (3V lithium) annually to maintain real-time clock accuracy. For troubleshooting, if IndustryPack® ports fail, reseat the modules and check DMA settings; if SCSI storage errors occur, test the cable and verify termination resistors (150 Ω). Store a spare MVME147SRF with matching firmware (VxWorks 5.5+) to minimize downtime in critical systems.
