Description:

The DM6856HR dataModule® offers high-density, low-cost isolated digital I/O. Isolated I/O are available as two 8-bit digital input ports and two 8 bit output latches. The output latches drive open-collector-output Opto-isolators.

The DM6856HR can be used to safely interface to control equipment in the presence of high voltages, ground faults, and current loops which would damage non-isolated I/O.
