Configurable Thermocouple TransmitterWall Mounting With Connection 3 (or 2) Wires, HD786TR1 2 are 420 mA configurable transmitters with microprocessorfor Pt100 Platinum temperature sensor.They convert the temperature variations found with any standard Pt100sensor (100O at 0C) into a linear current signal with two leads in the field420 mA. Linearization with a digital technique allows excellent precisionand stability to be obtained.User can set the 420 mA output (or 204 mA) in any temperature rangewithin the field -200...+650C, with a minimum amplitude of 25C; it maybe simply reprogrammed by pressing a key, without any need to regulatejumpers, potentiometers, software, etc. A led indicates any alarm situations(temperature outside the set range, broken or short-circuiting sensor) andassists the user in the programming phase.
