Mr HaECO ALFA SYSTEM
The most compact, cheap and easy-to-cable solution with Economizer, suitable for filters up to 24 valves.
ECO-ALFA is an economizer with built-in differential pressure sensor able to pilot up to 24 ALFA remote modules (each equipped with a ¼” pilot which commands pneumatic valves).
It has an LCD display on which the pressure measured by the sensor, the activated valve, the current cycle status (pause, work, post-cleaning, ... ), the type of operation, any alarms present, etc., can be monitored in real time.
ECO-ALFA is fully programmable and communicates with the ALFA unit by means of a patented system.
Each ALFA module is assigned a serial address, which identifies each individual board.
Using three keys, the user can access the programming menu and enter all the board parameters.
ECO-ALFA can also automatically detect the presence/absence of the off-take valve connected.
The main feature of this system lies in the ease of wiring, which is reduced to a single two wire cable that starts from the control unit and crosses one by one the ALFA unit mounted on each valve on the tank.
ECO-ALFA has 2 digital inputs and 2 clean contact relays.
The instrument is pre-engineered for an optional RS485 serial communication output, to be requested when the order is placed (RTU Modbus protocol), allowing it to exchange data with a PC/PLC and other data storage units
