SPS IPC Drives 2013 exclusive show report

has also developed a device for attaching Panel PCs and TFT screens easily to support arms. The Vesa 75/100 connection console can be assembled by one person. Another Rittal development is version of its SE 8 enclosure system with Nema 4/4x protection for the North American market.

The German safety specialist Schmersal has a new range of compact safety light curtains and light grids with a protection area covering the whole length of the 28 x 33mm profile, thus avoiding the need to leave an overhang. The SLC/SLG 440COM series includes six resolution variants and covers heights up to 1,770mm. The protection can be built into a machine’s housing profile without needing to consider dead zones. Another new series of light curtains and grids called SLC/SLG 445 adds functions such as muting and multiple scanning of protection zones.

Also from Schmersal is a safety sensor using an RFID-based failsafe technology that allows coding of individual actuators. The compact RSS260 sensors are available in various formats and with three levels of anti-tampering protection. Finally, Schmersal was also showing a new generation of safety hinged switches designed to replace conventional hinges on rotating protection doors and to monitor their position.

Siemens launched an entry-level motor management system that provides protection, control and monitoring functions for fixed-speed LV motors at “an attractive price”. The 22.5mm-wide Simocode pro module provides: direct and reverse starting functions; thermistor and overload protection; four digital inputs and two outputs; and monitoring of current limits, shutdowns and operating data.

The German safety equipment manufacturer steute was showing several additions to its wireless technologies, including a battery-free wireless module that allows existing cabled command devices, such as on/off switches, to be adapted for use in wireless networks. As the device (shown above) is actuated, a generator inside its contact block produces the power needed for the wireless transmissions, avoiding the need for a power supply. The module can convert devices with 22mm bayonet nut connectors to wireless operation.

Steute was also demonstrating a bidirectional Ethernet gateway that allows switchgear from its wireless range to be connected to terminals that communicate via TCP/IP. The receiver can accept and pass on signals from up to 40 sensors with a transmission rate of 100/10 Mbit/s. There are three versions of the gateway for various wireless networks, including EnOcean.

Wago announced a range of electronic circuit breakers with two, four or eight outputs and current ranges from 0.5–10A. The nominal output current of the Epsitron breakers can be adjusted in six levels for each channel using a rotary switch. Resetting of tripped channels and on/off switching can be carried out remotely. The eight-channel versions are 42mm wide, and the others are 45mm.

Weidmüller demonstrated a range of industrial relay modules for use where actuators experience high voltages and currents – when actuating motors, for example. The D series relays avoid arcing problems by using series contact connections, blowout magnets (to extinguish arcs), and low-wear contacts. They can handle loads up to 10A, 220V DC.

Werma has developed a new version of its Vocal Element signal tower accessory which can broadcast any audio file at a volume of 102dB – said to be loud enough to be heard in the noisiest factory. The device can store 15 different files. Werma also has a new slim LED signal tower (called Kompact 37) with five light colour combinations and a siren, and a range of compact LED beacons with a choice of seven colours.
