FC SERIES
DISTRIBUTOR
DATA SHEET
PXM
This distributor is to be installed for each group of FC/
FCX series transmitter and receiving instruments, compact
controllers and so on combined therewith.
While receiving power from a system power supply, the
distributor functions to provide DC power to a transmitter
and convert current signal from the transmitter into voltage
signal of 1 to 5V DC with a precision resistor for distribution
to individual receiving instruments.
FEATURES
1. The terminal structure allows easy connection of an external cable, and the transmitters of up to 4 loops are
connectable to one distributor.
2. A current limiting circuit is provided for each loop, and
an arrester can be built in at option.
3. An output backup function can be built in for prevention
of short circuit faults.
