Two-Channel Safety Switching Device
The SNV 407xSL is a two-channel safety switching device for various safety-related applications and fulfills all requirements of the standards EN 954-1 (Category 4), EN 61508 (SIL 3) and EN 62061 (SILCL 3). The SNV 407xSL conforms to EN 60204-1 and is equipped with positivly driven contacts.
After supply voltage has been connected to terminals A1/A2 and the safety inputs closed, operating the reset button closes the enabling current paths (manual start). When the safety inputs are opened/de-excited the enabling current paths will open immediatly or with an adjustable off-delay time.
The SNV 407xSL is available for a supply-voltage DC 24 V or AC 115 - 230 V in a small housing with 45 mm width for DIN rail mounting.
