Monitor machines and plants, e.g., for compliance with a set speed. Also available with integrated measuring transducer.

Individual processes are controlled independent of each other. In case of failure or malfunction of one component, it can therefore be necessary to switch off the hardware of a complete machine or plant.

Controls for suction plants in timber and plastic processing industry ensure, that dust at processing machines is sucked off according to the technical rules for dangerous materials TRGS 553.
They recognize the operating state on/off of a machine by measuring the current in the cable to the machine. This reduces installation.
Simple devices start suction plant as soon as at least one of up to 12 machines is switched on.
Devices with more features optimize function of plant by opening valves at active machines only. This improves power of suction, saves energy and provides high possible savings in measures according to directive for energy efficiency 2012/27/EU.
STW1641P controllers (programmable via IP interface) in conjunction with bus modules STW161M and STW168M reduce the wiring work of extraction systems with up to 32 machines. Gate valves are connected to a common bus line that is also used for a DC 24V power supply.
