the values of capacitance and inductance;
(2) For circuits containing up to 1 % inductance or up to 1%
capacitance with a cable, allow the values of capacitance and inductance;
(3) For connection of the combined inductance and capacitance where
both are greater than 1% of the allowed value (excluding the cable), allow

2-wire HART transmitter, 3-wire transmitter, current source input
isolated barrier(2 channels), provide isolated dc supplies for transmitters
which located in hazardous area. Transfer 4~20mA signal((or current
source signal)) which generated by the transmitter form hazardous area
to safe area separately, also allows bi–directional transmission of HART
communication signals. The product needs an independent power supply.
Input circuit,output circuit and power supply are each galvanically isolated.
(1). The air should not contain any medium corrupting the coat of
chrome,nickel and silver.Moreover,violent quiver and impact or any cause
of electromagnetic induction (such as big current or spark,etc.)must be
avoided when using.
(2). Operating temperature: -20℃~+60℃
(3). Storage temperature: -40℃~+80℃
(4). Relative humidity: 10%~90%
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
state-authorized explosion-proof product certification bodies.
