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.)
