NPFSR-K122YMD

The inputs of K series E-STOP, safety gate input safety relays are normally closed contact signals, which are used for emergency braking or the protection of people entering dangerous areas, and widely used in machining and other industries. Main features: 1oo2 architecture. With detection of shorts across contacts. With monitored manual reset function. The safety function remains effective in the case of a component failure. The correct opening and closing of the safety function relays is tested automatically in each on-off cycle.
