DST-660X-EX-ab-K8/K8 switch quantity output isolated safety barrier

Classification:

Switching quantity output

DST-660X-EX-a/b-K8/K8 is the isolation barrier of the switch output operation terminal, which controls the power supply of the safe area through the switch to drive the on-site safety equipment in the dangerous area. It allows the control switch to be directly connected to any end of the 24V power supply circuit. This product is suitable for driving such as solenoid valve, sound and light alarm and other safety equipment. According to GB/T 3836.1-2021 and GB/T 3836.4-2021, it has passed the inspection and obtained the ccc certificate. It is suitable for installation and use in safe areas and can be used together with intrapexy safety equipment in Zone 0, Zone 1 and Zone 2 of explosive gas hazardous places.
