Universal auto-manual stations
AMS400A
Typical application of AMS400A
The AMS400A modules are interface devices which are
used between controllers / PLCs and valves / actuators in
the field. They implement aouto-manual transfer operations
for automatically controlled processes.

In AA (analogue-analogue) mode, it is possible for a remote
source to switch between manual and automatic operations
using digital inputs. Ramp rates and additional handover.
Two options are available for the method of returning to
automatic control, in order to ensure a bumpless transfer.

The AMS400A offers three different I/O configurations,
which serve as interfaces between:
Analogue control equipment and analogue control devices
• • Digital control equipment and analogue control devices
• Digital control equipment and digital control devices
Acknowledge
4 to 20 mA input
PLC
• Manual start-up of sensitive processes before handover to
automatic control
• Manual over-ride in case of controller failure or
malfunction.
