Ethernet io controller

The Ethernet IO controller is a collection and control device used for converting I/O data to Ethernet. The port has overcurrent and overvoltage protection, and the module has electromagnetic isolation protection. It adopts the standard Modbus TCP/ RTU communication protocol and can be transmitted through TCP/ The IP network remotely collects IO signals and seamlessly connects them to the customer’s system.

For example, the ZHC1921 independently developed and produced by Zongheng Intelligent Control is an industrial-grade IO controller that provides 1 RS485, 6 switching inputs, 2 high-number pulses, 4 switching outputs and 4 analog input interfaces, supporting 4-way Socket, Modbus RTU/TCP adaptive, local logic processing calculation, automatic collection and active reporting, DO remote follow AI/DI, configuration cloud real-time monitoring PLC, automatic IP address acquisition, DNS domain name resolution and other special functions, supports one pair One/one-to-many/many-to-many networking, built-in web page to configure device parameters, allowing users to connect and debug equipment on-site or remotely.

This IO controller adopts the standard Modbus RTU communication protocol and is suitable for on-site applications of various industrial monitoring. It can also be easily integrated with third-party SCADA software and PLC equipment.

It also provides an RS485 interface, supports convenient and flexible cascading methods, realizes the combined expansion collection of various digital and analog quantities, and realizes network access at the lowest cost.

The IO controller can be used to collect switching signals and control the output of switching signals after judgment by the configuration software. It can realize remote control of remotely distributed equipment and is widely used in smart homes, power monitoring, computer room monitoring, environmental protection testing, and industrial automation. , intelligent manufacturing and other scenarios.
