Characteristics:
•
four common galvanically isolated active output safe circuits
(“common ground”) with 0 ... 20 mA- or 4 ... 20 mA interface:
− maximum feeding voltage:
approx. 9 V
− maximum permissible load: 300 Ω (in the trough)
•
maximum measurement error:
±0.1 % of the measurement
(in the measuring range 4 ... 20 mA and 0 up to 40 °C ambient
temperature)
•
maximum cable length:
500 m
