4CH Industrial Ethernet RTD Module(2 or 3 wires PT100/PT1000)

No.M240E
The BLIIoT M240E is a robust RTD Input Module designed for industrial environments, offering high-precision temperature measurement with support for 4RTD 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 M240E Industrial Ethernet RTD 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 M240E 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 M240E 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.
