Multifunctional safety relay for smaller machine applications

The PSR-MXF multifunctional safety relays from Phoenix Contact monitor up to three safety functions in one module. Safety-related control circuits with up to PLe or SILCL 3 can be created with the relays.

The new product range comprises four different special function modules, with three terminal block versions each. Different protection areas can be monitored in one machine, thanks to two local sensor circuits. Safety concepts are thereby simplified and machine productivity is increased.

Furthermore, the relay has a higher-level sensor circuit, which can be used for emergency stop signals, for example. All relevant sensors can be monitored, such as mechanical emergency stop signals or safety door locking, light grids, and magnetic switches.

The device does not need to be configured and for this reason, is particularly easy to maintain. The push-in fast connection technology enables tool-free installation which in turn reduces start-up times

UPS with IQ technology
Also new from the company is the Quint AC UPS uninterruptible power supply, which achieves high system availability for loads with 120 or 230Vac and 500VA power. A pure sine curve is available for the output voltage, so that even sensitive loads can be operated without interference on networks from 80 to 264Vac.

The power supply is already integrated in the housing. Power storage rounds it off and converts it into an intelligent UPS solution. As such, the load is consistently supplied during mains operation as well as in the event of mains failure.

The offline UPS is combined with power storage in VRLA technology with 3.4 to 38 Ah. For a longer service life and buffer times of up to 45 minutes at 15 W power, the power storage with lithium-ion technology is ideal.

The UPS-CAP power storage devices with maintenance-free dual-layer capacitors achieve a maximum service life of over 20 years at ambient temperatures of -40°C to +60°C. With VRLA-WTR batteries, buffer times of two hours at 400 W power or 40 hours at 15 W power can be achieved.

The integral IQ technology communicates with the power storage and determines all relevant states such as voltage or temperature. With this transparency, the reliability of the UPS and the optimum use of the battery is ensured.

The intelligent battery management detects the current charging state of the connected power storage device and uses this to calculate the remaining runtime. The remaining life expectancy of the battery is also known.
