OEM ODM M730-Remote I/O Module
Description
The M730-Remote I/O Module is a sophisticated signal conditioner designed for precise temperature, mV, and Ohm measurements. This 3-channel input module features RS485 communication, ensuring robust connectivity and data transmission. With built-in isolation between each channel, power, and network circuits, it effectively eliminates potential ground loops, enhancing measurement accuracy. The device operates under the widely accepted RS-485 Modbus RTU protocol, making it compatible with various applications. It supports both AC and DC power sources through nonpolarized, diode-coupled terminals. Whether functioning as an independent temperature transmitter or in conjunction with the MWG1 to establish a remote I/O DAS, the M730 excels in versatility, supporting both MODBUS RTU and MODBUS TCP protocols.
