hart safety barrier intrinsic isolator switch 420ma safe barrier 1 in 2 out

The siglal of switch quantity(dry contact or proximity switch )from dangerouarea is transformed into relay signal by isolation and output to safety area. Thet and output forwardand backward functions can be set by dialing switch, andIction canbe simplified. The three terminals of inputoutput and power supply are isolated.
This product is a simulation design. It has many advantages such as high reliabity and fast response. It can be used with various instruments, DCS and PLC
