Abaco Systems / VMIC VMIVME-2131-110 64-Bit Current Source / Sink Driver

The Abaco Systems / VMIC VMIVME-2131-110 is a 64-channel current source/sink driver module for VMEbus systems. It delivers continuous output up to 500 mA per channel with peak currents reaching ±3.5 A (100 ms, 10% duty cycle) across an 8 to 35 VDC output range. Each channel is jumper-selectable for source/High-Z or source/sink operation, with integrated transient and thermal shutdown protection. The module features eight independently addressable ports supporting 8-, 16-, or 32-bit VMEbus transfers, making it ideal for high-current switching and load driving in industrial test and control applications.
