INPUT SPECIFICATIONS

■ DC Current

Current range: 3.75 to 22 mA DC

Voltage drop: Approx. 3.5 V with 4 mA; approx. 3.7 V with

20 mA (Equivalent input impedance: Approx. 185 Ω)

(Use of the unit causes voltage drop. For 2-wire transmitter,

be sure that the voltage by which 2-wire transmitter can

operate is ensured including the voltage drop by other

devices and wiring resistance.)
