The SDM-6TE module measures temperature values with thermocouples PT100, Ni100, KTY81-110 and thermocouples (J, K, T, N, S, R, B). The value is read using the RS485 bus (Modbus protocol), so you can easily integrate the module with popular PLCs, HMIs, or PCs with appropriate adapters.

The module communicates with all commercially available PLCs, devices that support the popular MODBUS MASTER protocol.

The unit has a set of 6 temperature inputs. It is possible to measure 2 or 3 wire PT100 sensors and 2 wire thermocouple voltage measurement. In addition, the module is equipped with 2 configurable NPN outputs.

This module is connected to the RS485 bus via two wire twisted pair. Communication is made using the MODBUS RTU or MODBUS ASCII protocol. The use of a 32-bit ARM core processor provides fast data processing and fast communication. The transmission speed is configurable from 2400 to 115200.

The module is designed for mounting on DIN rail according to DIN EN 5002.

The module is equipped with a set of LEDs used to indicate the status of connected sensors and outputs, useful for diagnostic purposes and for troubleshooting.

Configuration of the module is done via USB with a dedicated computer program. It is also possible to change parameters using the MODBUS protocol.
