3.7.5 4 analog inputs 0/4 ... 20 mA (12 bits) − EPM−S403
This module detects up to four analog control signals from the process level and transmits
them to the higher−level bus system.
Features
ƒ 4 analog inputs
ƒ Current range 0/4 ... 20 mA
ƒ 12−bit resolution
ƒ Signal function is parameterisable
ƒ An LED indicates if an input signal is outside the permissible measuring range
(
Stop!
Overvoltage at the inputs
The electronics of the electronic module are not protected against too high
input signals.
Possible consequences:
ƒ The module is destroyed
Protective measures:
ƒ Make sure that the signals and encoders connected match the measuring
range parameterised.
