General
The AMS400A acts as an interface between digital controlling
equipment and a digital control element. It can also provide power for
control elements like valve actuators.
When in automatic mode the AMS400A will adjust the control element
in response to pulses on two digital signal lines from the controlling
device. In manual mode operator adjusts the element and the
“automatic” signals are ignored.
Display
The display provides feedback using the analogue current/voltage
input from the control element or from a suitable measuring device. For
example, if you are controlling a valve, you may want to display the flow
rate.
StatusOutputs
There is a digital ‘status’ output to the controlling device to signal the
operating mode of the AMS400A, i.e., automatic or manual.
