Existing MIWI350 supports only two pressure connections. An additional Pressure, P3 option is now
enabled for additional pressure measurement and to monitor the pressure.
A simple pressure regulator station contains minimum of three pressure taps to monitor under abnormal
conditions:
1. Regulator Input
2. Regulator Output and
3. Pressure Alarm (which is now available with P3).
To enable P3, MIWI350 uses Pressure Expansion (PE) Board which allows the customer to connect up to
three pressures and monitor the alarms with the third pressure connection.
PE Board is an additional PWA mounted inside MIWI350 casing adjacent to Power Distribution Board and
is a complete retro fit to current MIWI350 solution.
Pressure Expansion (PE) Board to Input-Output Board internal wiring connections:
