§Small-sized plug-in transducer§
2-output type

Distributor
FWDT■ Application
Supplies electrical power to a 2-wire transmitter, receives aDC4-20mA signal from the transmitter, then insulates andoutputs a proportional DC signal. Because this transducer
can extract two insulated outputs, control and monitor can bedone by a single unit. Up to 16 units can be housed in an
installation base.

■ Feature1.

29.5×76×125mm/180g

Compact and high withstand voltage.
Withstand voltage between input/output/auxiliary supply/outer case is AC2, 000V
(50/60Hz) for 1 min..
Withstand voltage between outputs is AC500V (50/60Hz) for 1 min..
With distributing and signal converting function, this is a distributor for two-wiretransmitter use.
With transmitter power source short-circuit protection (limited current 23-30mA).
A DC4-20mA signal from transmitter monitored as a DC 1-5V(±0.1%) signal throughsocket (FW11) terminals 3-4.
Constant voltage/current output type. No need to adjust the product if it operates
within load resistance range.
A LED can confirm status of electric power applied.
Zero/span of 1st and 2nd output can be adjusted individually. (±2% adjustable)
