STW161M

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

Bus module for controlling sliders in extraction systemsSTW168M 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).Function and propertiesModule for connecting up to 8 slidersOutputs potential-free changeover contacts for 24 or 230 VInputs for detecting the operating status of the machines (on/off), response threshold 0.5...9.9 A adjustable on the STW164IPControl via STW164IP (max. 4 x STW168M can be connected)Bus address 0...31 adjustableControl voltage DC 24 V (via 4-pole bus cable)LEDs for input and output statusesConnections via screw terminalsMounting Distribution board installation on top-hat rail EN60715Dimensions W x H x D: (without screw connections) 94 x 130 x 57 mmAccessories: ER6 mounting frame for panel mounting
