connector block provides the same
connections. Each channel has separate input terminals for voltage
(V
IN
) and current (I
IN
) input. Voltage and current inputs are
referenced to the COM terminals, which are internally connected
to each other and to the C terminals. All eight V

terminals are
internally connected to each other and to the V terminals.
You can use a 10–30 VDC external supply to power field devices.
