DST-606X-EX-38-a/b-V12 type frequency input detection terminal isolation barrier

Classification:

Frequency input

The isolation barrier at the DST-606X-EX-38-a/b-V12 frequency input detection end can provide 12V power supply to the hazardous area instrument, and the frequency signal generated by the hazardous area instrument is transmitted to the safety side output through the isolation barrier. The input has high anti-interference performance. The product requires independent power supply, input/output/power three isolation. This product can be used in frequency signal source and other 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.
