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

Resistance temperature transducer
FWRH■ Application
By inputting resistance value of a 3 conducting wire thermal
resistance based on the JIS, the device insulates input andoutput, and then converts thermal electromotive forces into
an output proportional to temperature. Because thistransducer can extract two insulated outputs, control andmonitor can be done by a single unit. Up to 16 units can behoused in an installation base.

■ Connection diagram (socket)●Specified current

Specified current is a current flowing into a thermal
resistance. Change of resistance value can bemeasured by voltage drop caused by the specifiedcurrent. Standard specified current is 2mA.

●External conducting wire resistance range

External conducting wire resistance is the conducting
wire resistance value which is the result of subtracting
the resistance value of objective resistance element. As
an influence of external conducting wire resistance, it
compensates when resistance values of all conducting
wires are equivalent, but it becomes error if resistancevalues of all conducting wires are different. Taking thevariousness of conducting wires into consideration, Use
it in a range less than or equal to 50 Ω per 1 line.
