8 Channel Thermocouple Temperature Input Module Modbus RTU/TCP
Product No.: ZH-T08TC
8 independent thermocouple input channels
Supports B, C, E, J, K, N, R, S, and T thermocouples
Temperature range:-270°C-2300°C
Up to ±0.1°C measurement accuracy
The ZH-T08TC Thermocouple Temperature Measurement Module is a high-precision industrial data acquisition module designed for reliable multi-channel temperature monitoring. Powered by a 32-bit high-resolution ADC and an industrial-grade ARM MCU, it supports nine thermocouple types (B, C, E, J, K, N, R, S, and T) with independent channel configuration. The module provides high measurement accuracy, excellent anti-interference performance, and supports Modbus RTU and Modbus TCP communication over RS485 or Ethernet, making it ideal for industrial automation, process control, furnaces, kilns, HVAC, energy systems, and laboratory applications.
