DYT 400 smart temperature transmitter

1),converted signal from Pt100, thermal resistance into 2 wire DC 4~20mA output 2),programmable /configuration by PC machine

DYT 400 Serial smart temperature transmitter

DYT 400 Serial smart temperature transmitter can divide into three specifications

DYT400-1H Serial smart temperature transmitter

DYT400-2H Serial smart temperature transmitter

DYT400-3H Serial smart temperature transmitter

DYT400-1H is thermal resistance input type, PC machine programmable

DYT400-2H is thermal resistance, thermocouple input PC machine

Programmable.

DYT400-3H is thermal resistance, thermocouple input, HART or PROFIBUS-PA protocol

\

Feature:

DYT400-1H series intelligent temperature transmitter converted signal from Pt100 into 2 wire DC 4~20mA output which correspond to the temperature and no relate to overload, can be programmable by standard PC machine, 3 wire thermal resistance configuration mode, upper and low limit alarm can be programmed, The precision is 0.1%, with sensor open loop detection function, and enhance capability of anti electromagnetic interference.

DYT400-2H series intelligent temperature transmitter converted signal from thermal resistance, thermocouple into 2 wire DC 4~20mA which corresponding to a temperature and unrelated to overload. can be programmable /configuration by standard PC machine, ,3 wire thermal resistance configuration mode, upper and lower limit alarm can be programmed, Input / output electric isolation, precision 0.1% ( typical), the stability of0.1%/ (typical), independent of the alarm circuit, excellent capability of anti electromagnetic interference. With independent parallel alarm circuit, continuous self diagnosis and self calibration.
