Designed for the organization of explosion protection of the "current loop" interface 4-20 mA;
The barriers provide long-term protection against short circuits in intrinsically safe circuits (automatically removed after elimination of the short circuit);
The barriers provide explosion protection due to the limitation of electrical power in the communication circuits with sensors and other technical means located in the explosive zone;
No power is required to operate the barriers.
- single or two channel;
- passive versions without galvanic isolation;
- conversion error 0.3%;
- HART (TWD) "transparent";
- can be used in conjunction with DVAXX1.X sensors;
- certified as measuring instruments.
