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

AC Current Transducer
FWAT■ 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 signal
directly to a distant place. Because this transducer can
extract two insulated outputs, a single unit can docontrol and monitor.
Up to 16 units can be housed in an installation base.

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..
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)
Because the device is RMS value operation type, it can also be used with adistorted waveform or a SCR waveform.
Current transformer does not open even if the device 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. Improper wiring 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]
2 A FW11 shunt resistance unit and a socket (FW11) shall be attached if 11-pin socket was specified. This shunt resistance unit is for exclusive use of
FW11 and can not be used in other specification.
3 An installation base shunt resistance unit shall be attached if installation base was specified. This shunt resistance unit is for exclusive use ofinstallation base and can not be used in other specification. There is no socket attached for installation base.
