Product Details:

MOTOROLA MVME147SRF belongs to MVME147S series 6U VMEbus single board computer, SRF stands for special rugged filtered version with enhanced EMI filter and conformal coating for harsh industrial environment. Equipped with MC68030 16MHz 32-bit processor and MC68888 floating-point coprocessor, configured with 4MB non-parity DRAM, two EIA-232-D serial ports, one Centronics parallel printer port and DMA SCSI interface. It integrates battery-backed SRAM, real-time clock, watchdog timer and VME system controller function, it does not carry onboard Ethernet transceiver. This legacy SBC is discontinued, available stock are refurbished spare units for legacy VME control racks, industrial test platforms and vintage CNC systems.

This CPU board acts as the main master controller inside VME chassis. It supports A32/D32, A24/D16 VMEbus protocol, works as bus master or slave and processes 7-level VME interrupts. The onboard VMEbug firmware supports serial debugging, memory operation and system boot configuration. The SRF revision adds extra filtering circuit and protective coating to suppress electromagnetic noise from servo drives and harsh workshop environment. It is widely compatible with classic real-time operating systems such as VxWorks.

It follows standard 6U double eurocard form factor, powered by +5V, ±12V from VME backplane. Front panel is equipped with SCON, RUN, FAIL, STATUS LED indicators, plus RESET and ABORT push buttons for on-site diagnosis. P2 rear connector expands SCSI and extra peripheral signals. Hot swap is not supported, power supply must be cut off before removal and replacement. Industrial PCB and vibration-resistant soldering process adapt to continuous factory multi-shift operation.

All units pass power-on self-test, memory detection, VME bus handshake test, serial and SCSI communication test and long-time aging test before shipment to guarantee stable real-time operation.

It is widely used on industrial test equipment, metallurgy control cabinets, factory measurement platforms and old CNC control systems. Typical application scenarios include VME rack main CPU replacement, legacy automation system maintenance and equipment retrofit. Automation integrators select this Motorola MVME147SRF for its rugged filtered design and non-Ethernet 4MB non-parity configuration.
