XVME-2121 The XVME-2121 digital input module provides 32 digital input channels. The module has a professional programmable scanner circuit that can detect A changing state on any of the 32 input channels. the

XVME-2121 eliminates the need for the host process  or to constantly poll digital I/O for signal conversion data. During interrupt transitions, modules can generate VMEbus interrupts.

This module is ideal for making contact with buttons or relays. It contains an input off-line circuit with eight jumper selectable stripping intervals, and a 12v supply on the isolation board. Optical isolation of 300 VDC and reverse bias protection of 50 VDC are also provided. It will accept input voltages from 10-50 VDC. The XVME-212/2 eliminates the onboard DC/DC converter and provides a TTL-level input signal.
