CLEARSY is evolving its range of SIL 4 certified safety relays (compliant with EN 50129). As safe and reliable as ever, the RS4 is now available with a wider voltage level!
In addition to the two existing formats — DIN rail and electronic board — RS4 vital relays are available in various contact configurations and supply voltage levels.
With this new version, the control voltage range has been extended from [72–110] to [48–110] VDC whilst remaining compliant with EN 50155, with a single part number.
