Contrinex introduces a high-speed safety relay for use with 'Safetinex' type 2 and type 4 light curtains. Thanks to a response time of just 10 ms, safety systems in accordance with ANSI B11.19 or EN ISO 13855 can be implemented with shorter overall safety distances. The safety relay is a category 4, PL e device and has been specially developed for personal and machine protection. It is suitable for use with safety light curtains, multiple light beam safety devices, emergency stop buttons or door monitoring systems. The two-channel relay in a DIN rail housing with a width of 22.5 mm has three safety contacts as normally open contacts and LED indicators for channel 1, channel 2 and the power supply. A manual or automatic mode for restarting is available.
