Abaco Systems / VMIC VMIVME-2210-000 64-Channel Momentary Relay Board with Built-in-Test

The Abaco Systems / VMIC VMIVME-2210-000 is a 64-channel momentary relay output board for VMEbus systems. It delivers 64 One Form C (SPDT) contacts via magnetic latching relays that retain state through power loss until commanded to change. Built-in test (BIT) logic monitors relay contacts and driving registers in real-time and offline modes for rapid fault detection and isolation.

The board supports 8-, 16-, and 32-bit data transfers with user-selectable addressing across A24, A16, D32, D16, and D08(EO) slave modes. Two front-accessible 96-pin DIN connectors provide relay I/O, with each relay assigned one row of pins: N.O. to column A, N.C. to column B, and Common to column C.
