Abaco Systems / VMIC VMIVME-2232-110 32-Channel Relay Output Board with Built-in-Test (BIT)

The Abaco Systems / VMIC VMIVME-2232-110 is a 32-channel relay output board for VMEbus systems with integrated Built-in-Test (BIT) capability. It delivers reliable control of external devices through 32 Form C (SPDT) relays, supporting switching voltages to 220 VDC and 250 VAC with maximum switching current of 2 A. The board accommodates 8-, 16-, or 32-bit data transfers across four 8-bit-wide ports, each addressable within the short I/O memory space.

Jumper-selectable address modifiers configure short supervisory or non-privileged I/O access modes. A Control and Status Register manages the front panel Fail LED, BIT functions, and relay enable/disable operations.
