PDA-T

The PDA-T module is a combination of the sPDA and TCM-K modules and facilitates the connection to the peripheral port to allow the simultaneous recording of 1 differential high-ohmic external voltage and 1 temperature.

Technical specifications

1 differential high-ohmic analog input:

• Each channel can measure the difference between + and ? inputs up to ?10V
• The maximum allowed common mode voltage is ?12V. This means that the potential of the inputs may have up to 12V difference from the instrument gnd (Agnd)
• Each input + and ? has a very high input resistance: > 1E12 Ohm
• Port interfacing: the voltage signal transfers to analog input1 of the potentiostat peripheral port

1 temperature signal:

• Suitable for K-type thermocouples
• The input of the thermocouple module is not isolated from the potentiostat?s ground. If isolation of the thermocouple is required, a thermocouple with isolated tip should be used
• Temperature range: 10 to 900C
• Measurement accuracy:
  • 10 to 400C is ?2C
  • >400C is ?1.6%
• The PDA-T can be used in ambient temperatures: 0 to 50C
• Output signal: analog output voltage of 5mV/C
• Port interfacing: the voltage signal transfers to analog input2 of the potentiostat peripheral port
