8RTD Dual-Ethernet I/O Module (2 or 3 wires PT100/PT1000)

No.M340E
The BLIIoT M340E is a robust Dual-Ethernet I/O Module designed for industrial environments, offering high-precision temperature measurement with support for 8RTD channels. Compatible with 2 or 3 wire PT100/PT1000 sensors, this RTD Input Module ensures accurate and reliable data acquisition for critical applications such as cold storage monitoring, HVAC systems and industrial automation.
Description
The M340E Dual-Ethernet I/O Module is an 4-channel isolated RTD temperature acquisition device designed for demanding industrial applications. It supports 2/3-wire PT100/PT1000 sensors, with a measurement range of -50~+300°C and an accuracy of ±0.1% FSR (@25°C, 12-bit resolution). The module features high reliability and precision, making it ideal for temperature monitoring in harsh environments.

Equipped with a 32-bit MCU and dual 10/100M Ethernet ports, the M340E supports Modbus TCP, RTU over TCP, MQTT and Modbus RTU Master/Slave protocols, ensuring seamless integration with SCADA, PLC or IoT platforms. The built-in RS485 interface allows for cascading additional Modbus RTU devices, while the register mapping function enhances data polling efficiency. The module operates on a wide voltage range of 9~36VDC with reverse polarity protection and includes a metal housing rated at IP30 for durability.

Configuration is streamlined through user-friendly PC software, enabling easy parameter setup and real-time monitoring. The M340E is designed for DIN rail or wall mounting and operates reliably in temperatures ranging from -20~70°C, making it a robust solution for industrial automation and temperature control systems.
