Product Description
Key Features
- Exact SIPLUS S7-300 identity: SM 331 spare part based on 6ES7331-7PF11-0AB0, with conformal coating and 1x 40-pole connection.
- Thermocouple input capacity: 8 analog inputs support thermocouples type B, C, E, J, K, L, N, R, S, T, U, and TXK/TXK(L) to GOST.
- Resolution and conversion: Resolution is 16 bit with Two's complement and overrange; integration time is parameterizable.
- Supply and isolation: Rated load voltage L+ is 24 V DC with reverse polarity protection. Analog inputs are isolated from the backplane bus and electronics power supply.
- SIPLUS environmental data: The supplied temperature range is 0…+60 °C, and the module has conformal coating.
Applications
- Thermocouple temperature measurement: Measures thermocouple signals through 8 analog inputs for supported thermocouple types.
