HART475 manual operator

Performance:

HART ® The handset can be connected to any HART through a 4-20mA current loop ® For compatible equipment, there must be a load resistance of at least 250 Ω in this current loop. The HART handheld device adopts the high frequency digital signal Bell202 frequency shift keying (FSK) technology, which can be superimposed on the 4-20mA current signal for transmission. Handset and HART ® The communication of compatible equipment will not affect 4-20mA analog signal.

Technical indicators:

● HART ® Interface technical indicators

● HART ® Interface complies with HCF (HART ® Communication Foundation) protocol, two-way half duplex 1200bit/s mode

● HART ® The interface can receive a common mode voltage of&# 177; 40V

● Typical value of leakage current is less than 1uA@20 ℃

● HART ® Interface communication distance<1500m

● HART ® The communication interface has anti EMI measures

● HART ® Communication interface has automatic amplitude multiplication function
