AMS400A
The AMS400A is an interface device
used between controlling equipment and
field devices to allow manual takeover of
automatically controlled processes. Typical
applications are:
• manual start-up of sensitive processes
before handover to automatic control
• manual over-ride in case of controller
failure or malfunction.
A fully configured AMS400A can be installed
in three I/O configurations, which interface
between:
• Analogue control equipment and analogue
control devices
• Digital control equipment and analogue
control devices
• Digital control equipment and digital
control devices
For analogue to analogue operation there
are digital outputs available to force a
change to automatic or manual mode.
You can also set ramp rates and handover
settings to ensure a smooth transfer of
control.
