7.4 Thermocouple Types
The following thermocouple types and temperature ranges are supported by onboard ITS-90
polynomial conversion functions:
Thermocouple Type Range ˚C Accuracy ˚C * Resolution ˚C
based on 1uVrms
noise
J -210 to 1200 ± 1.5 0.019
K -200 to 1372 ± 1.5 0.024
E -200 to 1000 ± 1.5 0.015
R -50 to 1768 ± 2.0 0.125
S -50 to 1768 ± 2.0 0.143
T -200 to 400 ± 1.5 0.022
*Total accuracy, allowing for the effects of millivolt measurement accuracy, cold junction
compensation and conversion to temperature using the onboard conversion functions.
7.5 Switch Outputs
Connection is via a 10 way screw terminal connector. 3.81 mm pitch
8 optically isolated MOSFET switches, each with an indicator LED.
External I/O supply required in range 10-30V
Output rating max 0.25A per output.
WARNING
The TCIC inputs are not electrically isolated from t
he TCIC
USB, RS232, RS485 or Ethernet ports and hence any attached
PC, PLC etc.
Sensor inputs must never be attached to hazardous voltages.
The channel input voltages, relative to TCIC GND, must never
exceed ±10 Volts.
