16Di/16ro 16 road digital isolation input module 16 channel relay output data acquisition control board rs485 modbus module The product is shipped based on the color or size of the main image of the product page. Description: module is 16 road digital isolated input, 16 road relay isolated output module, through the isolated RS485 interface output. The module uses standard Modbus RTU communication, can be directly adapted to all kinds of host computer configuration software, PLC, S and so on. The module power supply, RS485 communication and electrical signals are isolated from each , which effectively suppresses all kinds of series mode and common mode interference, and also ensures the stable and reliable operation of the module. 1,the use of RS485, MODBUS, RTU standard communication, with the host computer configuration software, PLC, industrial touch screen, networking, with communication status indicator 2,signal control, power supply, RS485 communication, electrical signals are isolated from each . 3,communication circuit adopts protection, anti-interference design, power polarity protection. 4,RS485 communication signal output interface adopts over-voltage and overcurrent double protection. 5,it can be widely used for signal acquisition and control in industrial field equipment. 6,the communication format can be set up by software.
