The two wire DAT1112 transmitter has been designed to give an output current signal of 4÷20 mA; this signal is perfectly linear and
proportional to the voltage generated by the thermocouple sensor connected to its input. The output current signal is supplied on the
same two wires used to power the device.
The user can program the full scale easily and quickly by means of four way DIP switch. The "zero" value can be varied between
-50°C to +50°C or -100 to +100 °F and the span value can be programmed following TC limits only.Moreover the same model is suitable
for K and J thermocouple, so as another model is suitable for R and S thermocouple. The maximum accuracy and reliability are ensured
for all the functions (conditioning, cold junction compensation and current transmission) thanks to the employement of high precision
and high-quality components and to the use of the SMD technology. The device, conform to the 89/336/EEC directives on
electromagnetic compatibility, is housed in a rugged self-extinguishing plastic case suitable for direct mounting on the connection head.
