Weight controller PWI-EX Ex-Proof case
The PWI-EX controller model of the PWI series in the Ex Proof explosion-proof housing is intended for use in industries with explosive and fire-hazardous operating environments. It can be used both as a weighing terminal for load indication and as a controller of various automation systems: test machines, tank weighing systems, filling, unloading, dosing, bagging systems. Due to the presence of various communication ports, the controller can be used together with various electronic devices, such as PLC, computer.
Features of the weight controller PWI EX:
- Ex Proof cast aluminum body
- 6-bit LED mass display
- Isolated magnetic type keyboard
- “Tare”, “Zero”, “Function” keys
- Tare input in the entire weighing range
- Determination of the output range according to the connected sensor
- Display of supply voltage and output resistance of sensors
- ROM independent of power failures
- RS232 serial port
