22) 4.20 mA OUTPUT CONNECTION

MULTIMODULE 133 module is equipped with two 4.20 mA outputs
With each 4.20 mA output it is possible to connect a read-out or acquisition device.
The admitted load impedance for each output goes from 0 to 500 ohms.
4-20 mA signal is referred to range 0-200°C with an accuracy of 1% with respect to full
scale value.
For the range 0-200 the ratio current/temperature is the following:
I = (T/12,5)+4 (T= temperature in °C)
out
Ex._:
If T=100°C I = 100/12.5+4= 12 mA (±0.2 mA)
