Modbus rtu Remote io Module RS485 Serial port Server Module for plc hmi Control

The M120 Modbus Remote I/O Module is an industrial class, isolated designed, high reliability, high stability and high precision data acquisition module, embedded 32-Bit High Performance Microprocessor MCU, provides a RS485 interface. It provides multi I/O, supports standard Modbus RTU, can be intergraded into SCADA, OPC server, HMI and other automation systems. It is design for working in the harsh industrial application environment, widely used in a variety of industrial automation, security monitoring system, automatically measurement and control system.

The M120 Modbus Remote I/O module provides 4 optical-isolated digital inputs,DI1 supports max. 10MHz high speed pulse counter, 4 isolated 12bits analog inputs, supports 0~5V,0~10V,4~20mA,0~20mA analog signal, 4 digital outputs, DO1 supports 10Hz~300KHz PWM high speed pulse output, or relay outputs, 2 channel 12bits analog outputs, supports 0~10VDC signal output. All of the I/O with high sampling frequency and special filtering strategy to ensure its reliable.

The M120 Modbus Remote I/O module can work at wide working voltage range, the range is 24 ~ 36VDC with anti-reverse protection design. Also, it provides 1channel 24~36VDC power output for external device to save wiring cost.
