Wieland Electric has expanded its offering of universal safety relays to include a small 22.5mm wide version. The SNO 4083KM series relay is the smallest in its class, making it attractive for most mechanical-engineering applications, particularly special machine engineering or smaller serial machines. The SNO 4083KM series relays are suitable for virtually any safety function, from conventional emergency stop, safety door monitoring, and monitoring of ESPE (electro-sensitive protective equipment)-type 4 (safety light curtain) to the monitoring of pressure mats or coded magnet switches with open-close contact pairs. Additional functions, such as a selective automatic or manual monitored restart of the safety function and synchronous time monitoring of 0.5 or 1.5 seconds for all two-channel applications, make the SNO 4083KM series a breakthrough in safety relays. The integrated Monoflop function detects short sensor signals to help eliminate debouncing, resulting in less downtime for the machine. "The SNO 4083KM series provides smart diagnosis of the device operating state to support economical machine operation, as well as the high operating capacity of the contacts," said Gary F. Meyer, product manager at Wieland Electric. The SNO 4083KM safety relays are used for conventional safety tasks in mechanical- and system-engineering and applications in lift engineering (according to EN 81-1) or in controls for industrial combustion plants (according to EN 50156-1). For increased safety, all of these applications are easily implemented without the user having to press a control button or connect additional configuration terminals. Wieland's SNO 4083KM relays can be used in safety-oriented applications up to PL e / Category 4 according to EN ISO 13849-1 and SILCL 3 according to EN 62061. The SNO 4083KM safety relays also feature a wide temperature operating range of ?25 to 65 °C. Pricing for the SNO 4083KM series safety relay starts at $225. Lead times are stock to three weeks.
