Speed and frequency monitor UH 6937
Now with safe phase sequence resp. rotational direction monitoring
In addition to safe speed monitoring, the sensorless speed and frequency monitor UH 6937 of the SAFEMASTER S series now also offers safe monitoring of the phase sequence resp. direction of rotation of motors with 3-phase AC voltages. If the motor does not move in the desired direction, the device switches off safely. Ideal for all applications where a safe direction of rotation is essential, such as automation processes, compressors, machine tools and wind turbines. The device allows up to four operating modes for different configuration of overfrequency, underfrequency, window range and direction of rotation.
- Simple and time-saving start-up without PC
- Direction of rotation monitoring fulfils Cat. 2 / PL d while retaining Cat. 4 / PL e for frequency monitoring
Speed and standstill monitor UH 5947
More than just drive monitoring
The safe speed and standstill monitor UH 5947 of the SAFEMASTER S series covers the combined application of encoder signals and PNP or NPN sensors. An alternative device version allows the use of NAMUR sensor technology. The device can be operated via the 4 buttons on the front and the LCD display, thus offers simple parameterisation. For example, the selection of the encoder, speed limits per operating mode and delay times can be flexibly adapted to your application.
- For safety applications up to Cat. 4 / PL e or SIL 3
- Controllable operating mode selection via input terminals
- Separate evaluation of speed and standstill
- Integrated safety gate monitoring
Solid-state relay PK 9260
Now with analogue input for burst firing control
The solid-state relay PK 9260/_4_ of the POWERSWITCH series with its 4 ... 20 mA analogue input for burst firing control suits perfectly for the control of heating elements and infrared lamps. It enables precise temperature control and offers a wide range of applications due to its noiseless and wearless switching, e.g. for injection moulding machines in the plastics and rubber industry, for thermoforming and packaging machines or in the food industry.
- „Ready to use” - due to optimally adapted heat sink
- Noiseless and wearless switching
- Vibration and shock resistant
- Long service life
- High plant availability
Three-stage enabling switch RE 6909
Holders for the enabling switch RE 6909
Machines and plants are subject to operating modes and situations in which it is necessary to stay in hazardous areas. With the three-stage enabling switch RE 6909 of the SAFEMASTER series, persons are safeguarded during commissioning, maintenance or set-up. For mounting the enabling switch on aluminium profiles, machine parts, protective fences etc., holders are now available in two different versions. These enable the optimum use for every application.
- Ergonomic design
- Modular design
- Various expansion stages
- Quick and easy mounting of the holders
