TT100 DIP switch type intelligent temperature transmitter
Details
The TT100 is a two-wire temperature transmitter that sets the measuring range through a dial switch, and also has a PC programmable function. It can accept thermal resistance signal input, linearize the input signal, output 4~20mA standard signal, and transmit it to DCS, PLC and other system control equipment;
Features：
1、Circuit design using lightning protection and electrical fast transient (burst group) interference
2、Ultra-low power design of internal circuit
3、Adjust the position of the DIP switch to adjust the range
4、With PC programmable function
