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.)

INSTALLATION
Operating temperature: -10 to +55°C (14 to 131°F)
Operating humidity: 30 to 90 %RH (non-condensing)
Mounting: Panel flush mounting
Weight: 30 g (1.1 oz)

PERFORMANCE
Accuracy:  ±0.1 % rdg ±1 digit× scaling-multiple
(When the scaling-multiple is less than 1, rounded up to 1.)
Temp. coefficient: ±0.3 digits× scaling-multiple/℃
(When the scaling-multiple is less than 1, rounded up to 1.)
Scaling-multiple = | (Display Scaling Value B - Display Scaling Value A) ÷ (default Display Scaling Value B - default Display Scaling Value A) |
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength: 500 V AC @1 minute (input to FE)
