The following thermocouple types and temperature ranges are supported by onboard ITS-90
polynomial conversion functions:

*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.
The TCIC inputs are not electrically isolated from the 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.
