Products comply with " GB3836.1-2010 Explosive environment No. One Part: General requirements for equipment "and" GB3836.4-2010 Explosive environment No. Four Part: the intrinsic safety type" I "Protection equipment", through the China explosion-proof inspection agencies strict test qualified, And made explosion-proof certification.
function
This product is compatible with the distribution and isolation Two Modes: distribution mode, to a dangerous place Two WireTransmitter Supply, sampling Transmitter Output Two Wire current signal through the isolation after processing into Four Wire current isolation mode, sampling signal output; Four Wire current signal through the isolation output Four Wire current signal.The toggle switch product side built-in can set the input mode. Optional One enter One A, One enter Two A, Two enter Two A.Isolated gate From the terminal energy into the limit of intrinsically safe dangerous places, so as to ensure the safety and explosion-proof system.
