The PRM expansion module provides additional inputs and outputs for the PR200 basic unit. The inputs and outputs of the module can be controlled by the PR200 as their own I/OS. The module is a passive device and cannot be used without connection to the base device via an internal bus. The module is manufactured in different modifications, which differ by the supply voltage. All modifications are made in a plastic housing for DIN rail mounting.Functions and properties: · Power supply independant of the basic device · same performance as PR200 base unit · Easy connection, removal and replacement · Electrical isolation between power supply and I/O groupsThis text is machine translated.
