Summarize Operation Conditions
Specification
Isolated barrier converters thermal resistance, thermal couple and
potentiometer signal in hazardous area into 0/4~20mA or 0/1~5V signal. It is
intelligent and has cold junction compensation function, RTD, TC, potentiometer
graduation and range can be configured through computer. The product needs
an independent power supply.Input circuit, output circuit and power supply are
each galvanically isolated.

Intrinsic safety explosion protection loop system
Special requirements have to be confirmed before using the intrinsically safe
explosion loop system(intrinsically circuit) which connected by isolated barrier
and intrinsically safe apparatus in field:
(1) The explosion level of intrinsically safe apparatus should meet the
requirements of operation conditions. The apparatus should pass the explosion
protection test and get the certificate by state-authorized explosion-proof product
certification bodies.
(2) The intrinsic safety parameters of isolated barrier and intrinsically safe
apparatus both are sure, and comply with 12.2.5 of GB 3836.15-2000.
(3) If any parameters are unclear, the system has to be confirmed by stateau
thorized explosion-proof product certification bodies.
