Not necessarily. It depends on whether the IO card of PLC/DCS provides external power supply.

CZ3047 outputs active signals, which are adapted to the situation where the IO card of PLC/DCS does not provide external power supply.

If the IO card of PLC/DCS provides external power supply, it needs the CZ3047T to output 4~20mA passive signals.
