Abaco Systems / VMIC VMIVME-1111-020 64-Bit High-Voltage Digital Input Board

The Abaco Systems VMIVME-1111-020 is a 64-bit high-voltage digital input board designed for VMEbus systems. This board is capable of accepting a wide range of input signals, including differential, electronic switching circuits, standard logic circuits, mechanical switch contacts, relay contacts, and Opto22 type signal conditioning modules. The input signal conditioning circuits are user-configurable, allowing for high-voltage current sink or voltage source options. The VMIVME-1111 is compatible with Abaco Systems’ Intelligent I/O Controllers, such as the VMIVME-90XX and VMIVME-9300 series. It also features on-board Built-in-Test (BIT) logic for fault detection and isolation, and a front-panel Fail LED. This product has entered a Restricted Production Phase (RPP) as of July 4, 2019.
