8Channel Analog Differential Input Module

No.M330E
The M330E Analog Differential Input Module supports 8 analog input channels with 4-20mA, 0-20mA, 0-5V and 0-10V signals, providing precise data acquisition. This Dual-Ethernet I/O Module uses Modbus TCP/RTU and MQTT protocols for reliable industrial applications.
Description
The M330E Analog Differential Input Module is an industrial-grade data acquisition and control module designed for high reliability and precision in demanding industrial environments. It features a 32-bit high-performance microprocessor and dual 10/100M adaptive Ethernet interfaces, supporting Modbus TCP, Modbus RTU over TCP and MQTT protocols. This module is ideal for seamless integration with SCADA systems, PLCs and other industrial automation platforms, making it suitable for applications such as smart grids, industrial automation and environmental monitoring.

The M330E offers 8 analog input channels with 12-bit resolution, supporting signals including 0~5V, 0~10V, 4~20mA and 0~20mA. Its RS485 interface allows for easy expansion by cascading additional Modbus RTU devices, reducing system complexity and cost. The module also includes a built-in register mapping function, enabling fast data collection and real-time response for critical industrial applications.

With a wide operating voltage range of 9~36VDC and built-in protections against surges, ESD and reverse polarity, the M330E ensures robust performance in harsh conditions. It provides an additional DC power output for external devices, simplifying installation and reducing wiring costs. The module's compact metal housing and support for DIN rail or wall mounting make it a versatile solution for industrial automation and IoT applications.
