QIO850 Quad Input/ Output Module

The module provides four monitored inputs and four potential free relay changeover outputs.

The outputs are monitored with parallel contacts of

the relays. The outputs can be connected to an Auxiliary

Voltage source and its voltage can be monitored.

Additionally, all the outputs can be connected to the HVR800, for switching high power galvanic isolated

loads. For more details refer to the HVR800 documentation.

The module has an integral loop isolator. If this activates

a yellow LED illuminates. The activation remains in place until the short is removed.

The digital input monitoring and isolator functions

are both configurable.
