DST-607-EX switch quantity input isolated safety barrier

Classification:

Switching quantity input

DST-607X-EX-a/b-c/d switching value input detection terminal isolation barrier can accept switch or proximity switch input from dangerous area, and output to relay or transistor output on safety side through safety barrier isolation. It has input state detection indication and can carry out forward and reverse control. The product needs independent power supply, and input/output/power supply three isolation. It can be used in NAMUR proximity switches, switches and other field equipment (including intrinsically safe switches such as pressure, temperature and liquid level) that meet the DIN19234. It has passed the inspection according to GB/T 3836.1-2021 and GB/T 3836.4-2021 standards and obtained ccc certificate. It is suitable for installation and use in safe areas and can be used together with intrinsically safe equipment in areas 0, 1 and 2 of explosive gas hazardous places.
