Typical application of AMS400A
The AMS400A module is an interface device which can be used
between control units and devices in the field. It carries out manual
take-over of automatically controlled processes.
Typical applications are:
PLC
Digital high/
low output
from PLC
AMS400A
Proportional 4 to 20 mA output
Acknowledge
4 to 20 mA input
PLC
sensor,
etc.
• Manual start-up of sensitive processes before handover to
automatic control
• Manual over-ride in case of controller failure or malfunction.

During analogue-analogue operating mode, it is possible to use
the digital outputs for switching between manual and automatic
operations. Ramp rates and additional handover modes can be
set globally in order to output signals to external controllers.
