Overview
Specifications
Probe Assembly

The TC-003 Digital RTD Temperature Transmitter is a unique device designed to transmit the temperature measured by a PT100 RTD sensor to a PLC digital input. Although it requires only one normal digital 24VDC input on the PLC, it provides an accurate temperature measurement for use in the PLC program.

It is packaged in a standard ANSI 2”, 50mm “hockey-puck” to be installed in the head of normal industrial temperature probe assembly. The TC-003 transmitter is connected to the normal PT100 RTD.

It measures the resistance of the PT100 RTD and then calculates the corresponding temperature. It then outputs the measurement as a low speed serial pulse train to a standard PLC digital input. The PLC receives 16 bits of data in a format ready to load into a 16 bit data register. The PLC register ends up containing the value of the measured temperature in degrees C x 10. For example if the measured temperature is -5°C the transmitted data will be -50, and if the measured temperature is +10°C the transmitted data will be 100.

Technical Information
Data format	Start pulse and 16 data bits, 2’s complement binary code, MSB first, °C x 10.
Start pulse	500mS +ve , 100mS -ve
Data pulse	Binary 0 - 100mS +ve, 200mS -ve Binary 1 200mS +ve, 100mS -ve
Rate	One reading every 8 seconds
Accuracy	Resistance ±0.1%, equivalent to ±0.3 ºC at 0ºC
Useful Range	-100ºC to +850 ºC
Resolution	0.1°C
Power Supply	24VDC , 20mA min 18V, max 30V
Connection	3-Wire +24VDC, 0VDC, output
Input	RTD PT 100, 3-wire DIN 43760, α = 0.00385
Output	- 24VDC “push-pull”, 100mA. - Output connection switches between 0V and +24VDC to operate correctly with normal PLC 24VDC sink or source input (“PNP” or “NPN”) - Output is short-circuit, overload and reverse polarity protected.
Transient protection	- Transients above 33V are absorbed by Tranzorb surge suppressors. - Continuous DC operation above 33V will destroy the sensor.
Physical	- 50mm diameter ANSI standard - Fully encapsulated electronics - Screw terminal blocks
