Abaco Systems / VMIC VMIVME-2510B-100 32-Channel Relay Output Board with Built-in-Test (BIT)

The Abaco Systems VMIC VMIVME-2510B-100 is a VMEbus-compatible 64-channel relay output board engineered for industrial and embedded control systems. This 6U double-height module delivers individual 8-bit port programmability, flexible I/O addressing, and integrated built-in-test (BIT) capabilities for real-time fault detection and isolation in mission-critical applications.

Technical Specifications

• I/O Channels: 64 TTL input/output lines organized as eight 8-bit ports
• Data Transfer Modes: 8, 16, and 32-bit transfers; block mode capable
• I/O Voltage: TTL-compatible logic levels
• Output Drive: 15 mA source, 64 mA sink per channel
• Power Supply: +5 V at 3.786 A maximum
• Operating Temperature: 0 to 55 °C
• Storage Temperature: -20 to 85 °C
• Humidity: 20 to 80 percent non-condensing
• Form Factor: VMEbus Rev. C compliant, 6U double-height
• Connectors: Dual 64-pin DIN 41612 connectors
• Thermal Management: Convection cooling

– Key Features

• Port Programmability: Direction of each 8-bit port independently selectable as input or output via CSR control bits
• Address Flexibility: Dual sets of address switches enable contiguous CSR and I/O memory mapping across multiple boards; DIP switches allow unlimited short data I/O address selection
• Access Modes: Jumper-selectable address modifiers support short supervisory or short non-privileged I/O memory space; factory configured for short supervisory access
• Built-in-Test: Dedicated hardware supports offline and online diagnostics; two independent TEST MODE bits enable per-connector loopback verification with I/O transceivers disabled; output data readable in real-time or offline; Fail LED indicates faults at power-up/reset
• Optional Outputs: Open-collector outputs available
• Addressability: Eight ports individually addressable on 8 or 16-bit boundaries; configurable as two 32-bit words, four 16-bit words, or eight 8-bit bytes

– Typical Applications

Relay switching and monitoring in avionics, defense, industrial process control, and embedded VMEbus systems requiring high-reliability I/O with integrated self-test.

– Compatibility & Integration

Fully VMEbus Rev. C compliant with block mode data transfer support. Memory-efficient addressing conserves system address space through contiguous CSR mapping and flexible I/O address assignment.
