§Small-sized plug-in transducer§
1 output typeAC current transducer
FSAT■ Application
Converts AC current in an electric power system intoa DC signal in proportion to input. With input andoutput insulated, the product offers full advantages intransmitting insulated signals between measuringsystems, cutoff of noise, protecting a control circuit froma sneak current, and transmitting an output directly toa distant place. Up to 16 units can be housed in an
installation base.

Compact and high withstand voltage.
Withstand voltage between input/output/auxiliary
supply/outer case is AC2, 000V (50/60Hz) for 1 min..
Constant voltage/current output type. No need toadjust the product if it operates within load
resistance range.
A LED can confirm status of electric power applied.
Zero/span is adjustable. (±2% adjustable)
Because the device is RMS value operation type, it
can also be used with a distorted waveform or aSCR waveform.
Current transformer does not open even if thedevice is pulled out from a hot line.

Note1) A purpose-built shunt resistance unit is attached to each kind of product as an accessory. The shunt and the product have identical numbers,
and make sure to confirm the numbers before use. If the numbers are different, it may result in a big error.
Note2) Wiring of shunt resistance unit must be implemented in accordance with Connection diagram. Miswiring or not using a shunt resistance unit
may result in open of current transformer (CT) and lead to a trouble.
* In the [Kind of specifications]
1: A FS08 shunt resistance unit and a socket (FS08) shall be attached if 8-pin socket was specified. Shunt resistanceunit for FS08 is for exclusive use of FS08 and can not be used in other specification.
3: A installation base shunt resistance unit shall be attached if installation base was specified. This shunt resistanceunit is for exclusive use of installation base and can not be used in other specification. There is no socket attached
for installation base.
