Energy saving systems: fan control, street light control, air conditioning control, equipment power control, etc;

Commercial applications: hotels, shopping malls, factories, internet cafes, offices, physical store monitoring, etc;

Unmanned: communication rooms, substations, water plants, airports, underground pipelines, mining equipment, security monitoring, etc;

Function Introduction

The upper computer PC is connected to the acquisition&control box through Ethernet, and sends command control or read commands to the intelligent acquisition&control box. After receiving the command, the controller executes relay on/off, stepper motor forward/reverse control, motor fixed length control, and reads switch input status.

This product is a perfect replacement for PCI IO cards. IO cards are expensive, and PCI slots are prone to poor contact, making installation and maintenance inconvenient and unreliable. This device adopts highly reliable serial communication and microcontroller to ensure reliable operation in industrial environments. In applications with compact computer space, this solution allows for the external placement of IO cards, saving space. It can be installed on rail mounted chassis/cabinets or wall mounted walls, and provides 10 output controls and 6 switch status readings, making the electrical structure more compact.

Advantages of this product:

1: The power supply has strong anti-interference ability and high stability, using choke coils and switching power supplies;

2: Output relay photoelectric isolation, strong anti-interference, minimal impact of load action on the product, using branded relays with stable performance and high reliability;

3: The output optocoupler uses high-speed nanosecond optocouplers, which can be used for controlling high-speed stepper motors or servo motors;

4: The optocoupler isolation uses an independent power supply, and the driver is isolated from the power supply of this product, using a branded power supply with stable performance;

5: The switch input uses photoelectric isolation and can be connected to key switches, relays, magnetic switches, infrared switches, etc;

6: Rich status indicator lights, including switch output status indicator lights, switch input status indicator lights, communication indicator lights, and power indicator lights;

7: Equipped with standard Ethernet communication port and internal TTL communication port, used for expanding GSM/GPRS/CDMA/Zigbee/WiFi/Bluetooth/RS485/RS422 module communication;

8: Built in alarm buzzer, can remotely control the alarm, remind and prompt on-site;

9: Support protocol customization or hardware customization;
