The power feed terminals make it possible to set up various potential groups with any desired voltages (KL9190) or with
the standard voltages of 24 VDC or 230 VAC (120 VAC). The power feed terminals are available with or without fine-wire
fuse. In order to monitor the supply voltage, the terminals with diagnostics report the status of the power feed terminal to
the Bus Coupler through two input bits. It is thus possible for the controller to check the distributed peripheral voltage
over the fieldbus.
