Applications
- Thermocouple temperature signal acquisition: Acquires thermocouple temperature signals through 8 analog inputs using the supported thermocouple types.
Key Features
- Isolated analog inputs: 8 isolated analog inputs for thermocouples; channel isolation is provided in groups of 2, and the channels are isolated from the backplane bus and electronics power supply.
- Supported thermocouples: Supports thermocouple types B, C, E, J, K, L, N, R, S, T, U and TXK/TXK(L) to GOST.
- Resolution and conversion: Resolution with overrange is 16 bit including sign, using Two's complement. Integration time is parameterizable; basic conversion time is 10 ms per module for up to 4 channels and 190 ms per module from 5 channels upwards.
- Temperature compensation: Parameterizable temperature compensation supports internal compensation, external compensation with Pt100, external compensation with a compensation socket, and a 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 a red Group error SF LED are provided.
- Supply and connection: Rated load voltage L+ is 24 V DC with reverse polarity protection. The required front connector is 40-pin; shielded cable length is max. 100 m.
