Switch module - IOTROUTER

Product introduction

High reliability

Características del producto

Logic follows – local logic
Logic follows – local logic

Local logic operations do not need to rely on the cloud

DO follows DI forward

DO follows DI in reverse

Greater than or equal to the threshold triggers DO

Less than or equal to the threshold triggers DO

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.

Support multiple protocols

Compatible with Modbus RTU/TCP and JSON protocols

Support MQTT, TCP, UDP multiple protocols

Otra introducción

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.
