ZLAN6802 8 channels DI AI DO RS485 Modbus i/o module RTU / data collector remote controller

ZLAN6842/ZLAN6802/ZLAN6844 are 8 channels remote IO controller 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.

ZLAN6802: It is an IO controller using RS485 bus to control. Compared with ZLAN6842, it only supports Modbus RTU protocol, but low cost, suitable for using RS485 bus to control relay, collect switch quantity and analog quantity. The default baud rate is 9600bps, can be custom setted.

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.
