The M Series 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 M Series Modbus Remote I/O module provides different I/O ports for variety applications. Includes optical-isolated digital inputs, compatibles dry contact and wet contact, supports max 10MHz high speed pulse counter, the DIN1 can be used for encode, digital outputs supports 10Hz~300Khz high speed pulse output or relay outputs, the DO1 supports PWM high-speed pulse output, the output duty cycle from 10-90%; DO2 can be used to control the direction of the stepper motor, isolated 12bits analog inputs, supports 0~5V, 0~10V, 4~20mA, 0~20mA analog signal, 12bits analog outputs, supports 0~10VDC signal output, resistance thermal detector inputs compatibles 2/3 wires PT100 and PT1000. All of the I/O ports are high sampling frequency and special filtering strategy to ensure its reliability.

The M Series Modbus Remote I/O module can work at wide working voltage range, the range is 12 ~ 36VDC with anti-reverse protection design. Also, it provides 1channel 12~36VDC power output for external device to save wiring cost.

4. Technical Specifications

Special instructions for ordering

1) If the model provides digital input, the DIN default type: wet contact, optional: dry contact. The input type cannot be changed after manufacturer delivered. The DIN1 default is high-speed count mode; it can be changed to low-speed count mode by open the shell and change the internal jumper. If require dry contact input, please note when ordering, if DIN1 require high-speed pulse count mode then must be wet contact.

2) If the model provides digital output, the DO default type: SINK, optional: Relay. The output type cannot be changed after manufacturer delivered. The DO1 supports PWM high-speed pulse output, the output duty cycle from 10-90%; DO2 can be used to control the direction of the stepper motor. If require relay output, please note when ordering, if DO1, DO2 used for high-speed pulse output then must be Sink.

3) The model number: M240, M340 support thermal resistance temperature transmitter default type: PT100, optional: PT1000, if you need PT1000 type of thermal resistance, please note when ordering.

4) The valid number of I / O ports corresponding to the model number is described in the Model List, the not included I/O port in the model is invalid, although in the hardware reserved them.
