Bus module for controlling sliders in extraction systems
STW168M and STW161M shutter modules control up to 8 shutters in extraction systems in conjunction with an STW164IP control unit. Up to 4 STW168M units can be combined with one STW164IP control unit. They are simply mounted next to the STW164IP in the control cabinet. Alternatively, they can be placed near the slide valves. In this case, the module only needs to be connected with one bus cable. The long supply lines to the sliders from the control cabinet are no longer required. At the same time, it is possible to use single modules STW161M in the same system (sliders on STW161M only DC 24 V).

Tip
Control for extraction systems via bus Type STW164IP
The basic function of the device is to detect whether a current is flowing in the supply line of one of several woodworking machines. If a current flow is detected, the device opens a valve on the machine's suction channel. At the same time, the extraction system is switched on. When a machine is switched off, the device closes the associated valve with a delay. If the last machine is switched off, the extraction system also stops after a delay.Control for extraction systems with connection slide valve via bus, control of up to 32 sliders via bus lineApplication:The STW164IP serves as a central control unit. It detects the operating status of the machines by measuring their current consumption in the supply lines (current transformer STWA1(H) ) or via potential-free contacts. It switches on the central extraction system and opens the shutters on the ducts to the individual machines. 8-fold shutter modules are used to control the shutters. These can be mounted next to the STW164IP or distributed throughout the system. The latter reduces the amount of wiring required.Additional shutters can be opened to optimize the air flow. They can be assigned to different lines and prioritized. It is also possible to control cleaning and discharge.Parameterization is conveniently carried out via the network (Ethernet). If the control system is connected to the Internet, it can also be parameterized remotely.Recording the operating hours of the machines and the switching frequency of the valves provides valuable services for preventive maintenance. This means that components can be replaced during a service call before they age and fail.Accessory: Front Mounting Kit type ER8 for mounting in control panels or doors
STW161M
Bus module for controlling sliders in extraction systemsSTW161M and STW168M bus modules control gate valves in extraction systems in conjunction with STW164IP control units. The wiring effort is drastically reduced by the bus technology.Application:Control of extraction systems in the wood and plastics processing industry in accordance with the Technical Rules for Hazardous Substances TRGS 553. The central automatic start-up switches the extraction system on as soon as a machine is put into operation. The shut-off valves in the extraction ducts of the individual machines are controlled via STW161M bus modules. DC 24 V is available as a signal. If required, the bus modules can also monitor the function of the shut-off valves (input for end position reached) and record the operating status of the extracted machine (on/off) via STWA1 current transformers or potential-free contacts and report this to the central control system.
