ZLAN6808 is an 8-channel remote IO controller launched by Shanghai ZLAN Information Technology Co., Ltd., which supports 8-channel DI/DO/AI, that is, digital input, relay output, and analog input (including voltage and current). At the same time, it supports the serial port server function, and connects the third-party RS485 collector and controller on the RS485 interface to achieve remote control.

Among them, DI supports dry node and wet node with optocoupler isolation, DO is the relay output, with 5A 250V AC or 5A 30V DC control capability, the first 4 channels of AI input support 0~5V voltage input, and the last 4 channels support 4~20mA current input. The ADC is accurate to 12 bits.

The communication mode of ZLAN6808 supports 4G, CAT1, RS485, Ethernet, LoRa, Zigbee, NB. The corresponding sub-models are as follows:

• It supports 8 channels of DI/DO/AI, which can be controlled remotely or locally.
• The AI supports 12-bit precision, and the data is rigorously tuned to ensure accuracy.
• At the same time, it supports the serial port server function and realizes the control of the plug-in third-party RS485 device through the network.
• Support DI control DO function, using a pair of ZLAN6808 can control each other through 4G/LoRa and other communication methods, easy to use.
• The sub-model supports 4G/CAT1/RS485/Ethernet/LoRa/NB and other communication media.
• It supports Modbus TCP, Modbus RTU, MQTT, JSON, HTTP and other communication methods.
• It supports connecting to various public clouds, and supports data transmission and delivery control in JSON format.
• Abundant indicators: display DI and DO status, network status, data flow communication status, etc.
• Provide RS485 or TCP/IP control demonstration software RemoteIO, which can demonstrate device IO control and AI data acquisition.
• The RemoteIO configuration tool is provided to flexibly configure parameters such as slave address and baud rate.
• It can provide complete RS485 control instructions and Modbus RTU instructions, which is convenient for engineers to integrate development.
• Factory settings can be restored with one click, including baud rate, station address, network configuration of communication module, etc.
