The NRGC-PN control unit can be used to control and monitor up to 32 interlinked RG_CM_N series solid-state relays or contactors. It has two RJ45 ports for the Profinet interface. Using the Profinet IO communication protocol, the switching processes of the solid-state relays can be controlled directly from the PLC and the real-time data from each solid-state relay can be recorded. The power specification from the PLC is converted directly into controlled full waves in the control unit, synchronized with the mains. This reduces the load on the PLC.

The switching process is resolved to a half-wave. This enables precise load control with maximum resolution. The current values for current, voltage, frequency, power, energy consumption and operating hours are available in real time. Diagnostic information relates to mains loss, load loss, load deviation and overtemperature, a short circuit in the load circuit of the solid state relay and the status of a solid state relay outside the set limit values.

Control and data acquisition via Profinet is suitable for all heating applications, especially for IR emitters, where fast switching behavior and reliable and precise temperature maintenance are crucial for the quality of the end product. Typical applications include plastic injection molding machines, PET blow molding machines, thermoforming machines, semiconductor manufacturing machines and glass production machines.

Miniature photoelectric sensor with IO-Link
The LD30 laser distance sensor is a class 1 laser device that uses laser time-of-flight (ToF) measurement to reliably detect even small objects at a distance of up to one meter. It enables two simultaneous physical measurements and has two physical switching outputs. Depending on the application, the photoelectric sensor can be used in "IO-Link" or "SIO" (standard input/output) mode. A process data variable representing the measured distance between the sensor and object is transmitted cyclically via the IO-Link interface.

Retrieving status and diagnostic information enables predictive maintenance and better planning of service and maintenance cycles. In addition, parameters such as scanning distance as well as time and logic functions can be easily configured and quickly adjusted, for example when changing products. The photoelectric sensor is available in an ABS plastic housing with protection class IP67 and dimensions of 30 x 10 x 20 millimetres, as well as a slightly larger version in a stainless steel housing with protection class IP69K. The sensors are equipped with a two-metre connection cable or an M12 connector plug and are suitable for all applications in which detection accuracy is required in the smallest possible size.

Safety module SMS31 is one of five new module types with a width of 17.5 millimeters.

Safety modules in a slimline design
With a width of 17.5 millimetres, the new multifunctional modules save space in the control cabinet. In addition, the series with the five types SMS20, SMS31, SMSA31, SM2H21 and SME41 replaces the existing range with 36 devices. The SMS20 and SMS31 modules are used for emergency stop buttons, safety gate monitors, limit switches, non-contact safety switches, single beam safety light barriers and for leveling elevator cars. Safety gate monitors, limit switches and non-contact safety switches with antivalent output are the application area of the SMSA31 series modules. The two-hand modules SM2H21 and the extension modules SME41 complete the series of safety modules with instantaneous relay output. as
