The VMIVME-1111 Differential Digital Input Board is designed to read a differential voltage from a variety of devices. The signals may originate from electronic switching circuits, standard logic circuits, mechanical switch contacts, relay contacts, Opto22 type signal conditioning modules or numerous other sources. The input signal conditioning circuits can also be configured by the user to accommodate high voltage current sink or voltage source options.
Features
- Double Eurocard form factor
- 8-, 16-, or 32-bit data transfers
- RS-422/RS-485-compatible differential line receivers provide ± 7 V noise immunity
- User-selectable input voltage thresholds (1.25...66 V)
- Front panel with fail LED
- 4 bits of differential or high-voltage digital inputs
- Each group of 32 inputs are jumper-selectable to monitor: contact closure, voltage source, current sinking, or differential signals
- On-board Built-in-Test logic for fault detection and isolation
- Open circuit provides logic zero or (jumper-selectable) logic one
- Input filter option
Recommended replacement: VME-1129
