8CH Thermocouples Input Module (B/E/J/K/N/R/S/T)

No.M350T
The M350T features 8 channels of thermocouple input modules, supporting various thermocouple types including B/E/J/K/N/R/S/T, making it suitable for temperature monitoring in diverse industrial environments. It supports Modbus TCP, Modbus RTU over TCP and MQTT protocols, ensuring efficient and reliable data transmission to meet the needs of industrial automation and smart grid monitoring applications.
Description
The BLIIoT M350T Thermocouples Input Module is an industrial-grade data acquisition device designed for accurate temperature measurement in harsh environments. It features a 32-bit high-performance MCU, a 10/100M adaptive Ethernet port and an RS485 interface, supporting Modbus TCP (master/slave), Modbus RTU over TCP and MQTT protocols for seamless integration with SCADA, PLCs and IoT systems.The module operates on 9–36VDC input and provides one 9–36VDC/1.5A output to power external devices.

This compact Thermocouples Input Module supports 8 isolated thermocouple inputs compatible with B, E, J, K, N, R, S and T types. It offers ±3°C measurement accuracy with cold junction compensation from -8°C to +7.9°C, ideal for precision temperature monitoring in industrial automation, energy and environmental control applications.

M350T supports cascading Modbus RTU slave devices via RS485 and provides 300 BIT + 300 16-bit register mappings for fast TCP polling. Housed in a metal enclosure with IP30 protection and DIN rail or wall mounting, it is well-suited for distributed temperature sensing in demanding industrial environments.
