M150T - KING PIGEON - 1*RJ45+1RS485+8DIN+4AIN+4DO Remote IO Module (MQTT, Modbus)

SKU: 19780787
The M150 is designed for IIOT Application and Industrial Automation, it provides 8DIN+4AIN+4DO, compatible with MQTT, Modbus RTU, Modbus TCP protocols, equips 1 Ethernet ports and 1 RS485 port.




The M150 Ethernet Remote I/O module provides a RS485 interface, through the RS485 bus, it can cascade Modbus RTU I/O devices or Modbus RTU meters, e.g.: a variety of digital input or digital outputs, analog inputs or outputs, thermal resistance IO module combination, save costs. At the same time, the Ethernet Remote I/O module has register mapping function, the cascade Modbus RTU I/O data are automatically collected to the mapping memory area, the Modbus TCP Client query without waiting then can get a quick response to meet the industrial timely requirements.

The M150 Ethernet Remote I/O module provides 8 optical-isolated digital inputs, supports max. 700Khz high speed pulse counter, 4 isolated 12bits analog inputs, supports 0~5V,0~10V,4~20mA,0~20mA analog signal, 4 digital outputs, supports 10Hz~300Khz high speed pulse output or relay outputs. All of the I/O with high sampling frequency and special filtering strategy to ensure it’s reliable.
The M150 Ethernet Remote I/O module can work at 12~36VDC with anti-reverse protection design. Also, it provides 1channel 12~36VDC power output for external device to save wiring cost.
