ATEX-compliant safety relay modules for areas with explosive atmospheres
For setting up safety systems compliant with the explosion protection requirements
The PROTEXT SRB 101-Ex (one safety release) and SRB 200 (two safety release) series are suitable for use in Ex zones. There are variants with monitored reset function (trailing edge) as well as with automatic or manual reset function. All these versions have a stop 0 safety release and optionally can be supplied with cross-wire short detection.
The four new safety relay modules can be used in intrinsically safe circuits in combination with, amongst others, reset buttons, emergency stop control devices, interlocking devices and safety magnet switches to the ATEX-Directive 94/9/CE. Due to the explosion category “n” to EN 60079-15, they can be used in IP 54 control cabinets in Ex zone 2 (gas).
