Applications
- Thermocouple signal acquisition: Acquires temperature signals from supported thermocouples through 8 analog input channels.
Key Features
- Analog inputs: 8 analog inputs for thermocouples, including types B, E, J, K, L, N, R, S, T, U, C and TXK/TXK(L) to GOST.
- Resolution and conversion: 16 bit resolution with Two's complement; integration time is parameterizable. Basic conversion time is up to 4 channels: 10 ms per module, over 5 channels: 190 ms per module, 8 channels: 80 ms.
- Thermocouple compensation: Parameterizable internal temperature compensation, external temperature compensation with Pt100 or compensations socket, and definable comparison point temperature.
- Diagnostics and alarms: Parameterizable diagnostics, diagnostic alarms per group, limit value alarms, hardware interrupts for channels 0 to 7, readable diagnostic information, and red Group error SF LED.
- Supply and isolation: Rated load voltage L+ is 24 V DC with reverse polarity protection. Analog inputs are separated from the backplane bus and electronics power supply; isolation is tested with 500 V DC.
