•Operation
General
The DPA/MAS allows you to monitor the difference between two
4-0 mA signals. Trip points are set on the value of signal A minus the
value of Signal B.
Inputsignalisolation
Both input signals must be able to share a common return. If this is
not possible then one of the signals will need to be floated by passing
it through a signal isolator. Both signals must be in the same format
(normally 4-0 mA).
