Logic following, logic between devices Point-to-point logic following Multiple devices can be combined arbitrarily, and multiple channels can be followed arbitrarily. |
|
Timing trigger A time point (Beijing time) can be set to trigger restart or switch actions · Scheduled restart After enabling the socket, set a scheduled action and restart regularly to ensure that the device is effectively connected. No longer do you have to travel across mountains and rivers just to restart your equipment, achieving true 24/7 non-stop service. · Set open close Open or close the DO switch at regular intervals for flood discharge, power on, lighting, etc. |

 |
Support 4-way socket The collected data can be sent to 4 servers at the same time. |
|
Unterstützung mehrerer Protokolle Compatible with Modbus RTU/TCP and JSON protocols Support MQTT, TCP, UDP multiple protocols |

Andere Einführung
The switching module developed by Zongheng Intelligent Control is often used to collect switching signals from on-site input devices (such as buttons, travel switches, temperature control switches, liquid level switches, etc.), convert the signals into low-voltage signals inside the PLC, and implement PLC Electrical isolation of internal and external signals.
In addition to the above-mentioned DI (switch input) interface, it also provides DO (switch output), which can be used for remote control, such as remote control of pump stations, remote control of street lights, etc.
