Product information
Overview
Key Features
- 8 isolated thermocouple inputs: The module has 8 analog inputs for thermocouples type B, E, J, K, L, N, R, S, T and TXK/TXK (L) according to GOST.
- 16 bit measurement resolution: Resolution with overrange is 16 bit including sign, with Two's complement.
- Configurable measurement functions: Integration time, temperature compensation, characteristic linearization and diagnostic functions are parameterizable.
- Channel and bus isolation: The analog inputs are isolated between channels, in groups of 2, and from the backplane bus and electronics power supply.
- 24 V DC supply and 40-pin connection: Rated load voltage L+ is 24 V DC, with reverse polarity protection. The required front connector is 40-pin.
- Compact module dimensions: Dimensions are 40 mm wide, 125 mm high and 120 mm deep; weight is approximately 272 g.
