[Specifications]：8DI+8DO
[Communication interface]：RJ45, RS485
[Working voltage]：DC 9~36V
[Installation method]：positioning hole, guide rail installation
[Product size]：110*40*100mm
[Introduction]：This high-performance distributed IO host supports standard Modbus TCP and Modbus RTU protocols and is suitable for data acquisition and control. The device is equipped with 10/100M adaptive dual Ethernet interfaces and supports switch functions. The internal bus speed can reach up to 1ms. It has the characteristics of switching and analog disconnection output reset to ensure that it can be restored to the preset state when communication is interrupted. The product shell is sprayed with three-proof paint, which has the functions of "anti-mold", "anti-humidity" and "anti-salt spray".
