5.4 Extension module
equipped with analogue inputs and
outputs (e.g. MPA-EM1/3):
Analogue outputs
0/2...10 V, load >= 2 kilo ohms
0/4...20 mA, load <= 500 kilo ohms
(Attention! The output must not con-
nected to GND!)
Analogue input
0/2...10 V, Imax = 0.5 mA
or
0/4...20 mA, apparent ohmic resist-
ance R <= 500 kilo ohms
The inputs and outputs are NOT
electrically isolated from the mains!
