wifi remote control 8 channels DI DO IoT solution MQTT modbus TCP

ZLAN6842/ZLAN6802/ZLAN6844 are 8 channels WIFI LAN RTU i/o module Remote modbus TCP IO launched by Shanghai ZLAN after ZLAN6042. The controlled channels from 4 channels of 6042 extending to 8 channels, including 8 channels DI/DO/AI input. The DI support dry contact and wet contact with opto-isolator; DO is relay output with 5A 250VAC or 5A 30VDC control ability; the before 4 channels of AI input support 0~5V voltage quantity input, the after 4 channels support 4~20mA current input, the accuracy is 10 bits. ZLAN6842/ZLAN6802/ZLAN6844 respectively support 3 communication methods of Ethernet, RS485, Wifi.

1)       8 channels digital quantity input:

Support passive switch value (dry contact) and active level (wet contact). The active level range as below:

2)       8 channels digital quantity output:

The output type are relay output (5A@AC250V/DC30V).

3)       8 channels analog quantity input:

In default the first 4 channels are 0~5V voltage input, the after 4 channels are 4~20mA. If need customized, can modify any channels to the below 4 types:

(1)Current signal input: 4~20mA

(2)Voltage signal input: 0~5V

(3)Voltage signal input: 0~10V

(4)Resistance impedance input: 0~10k or resistor-type temperature humidity sensor, etc.

4)       8 channels switch value input state and 8 channels switch value output state both have independent indicator, can immediately know switch input/output state through indicator.

5)       Provide demo software Remote IO controlled by RS485 or TCP/IP, can demonstrate IO control and AI data acquisition for devices.

6)       Can provide complete RS485 control instructions and Modbus TCP commands, convenient for integrated development of engineer.

7)       ZLAN6842/ZLAN6844 are freely equipped Windows virtual port & device management tool ZLVircom, support ZLVircom, can one-key search and modify parameters.
