The absolute best performance in vacuum control !

The PLC-250 PLUS vacuum controller is the high performance control system from ProVac®, for the highest performance in die and sleeve evacuation with fully reliable operation. 

The Programmable Control Unit to operate either one or two Vacuum-valves, piloted by the liquid metal or by the die-casting machine, offers in addition advanced vacuum analysis and monitoring.

The main features of the PLC-250 PLUS are

• A Siemens CPU-226 Programmable Logic Controller (PLC) communicating with a Simatic OP-73 micro panel or a Simatic TP270 touch panel
  Or:
• A Allen-Bradley CPU L23 PLC communicating with a TP PanelView PV Plus 600 Color
• Automatic start-up security at beginning of operation and after interruption of the casting cycle
• Digital indicator for“Vacuum valve 1”, “Vacuum valve 2”, Pollution control, “Vacuum  tank”
• Impulse cleaning and cooling of the vacuum valve
• Automatic valve control of suction capacity
• Vacuum control in the valve
• Compressed air control
• Multiple display lamps
• Interface to the die-casting machine  by 24-pin Harting plug for signals and alarms
• Mounted in carriage on a 250 litre tank, size : 1870 x 550 x 1000 mm (Height x Width x Depth)
• Vacuum pump: 40 m3/h
• Power: 230 – 400 V / 50/60 Hz, 1.1 kW
• Compressed air connection: 5 – 6 bar

Advantages :

• High performance, Monitoring, Analysis, Archiving;
• Permits the use of the ULTRA valve, the best solution for large castings in all situations;
• Affordable price;
• Easy change of the parameters on the OP-73 or the Touch Panel
• The VAMP offers totally new perspectives for improving the pressure die-casting process and not just for monitoring die evacuation.
