Various models can support RS485, and P2P communication. Support 8-way relay output, 8-channel digital input, 4-channel voltage and 4-channel current acquisition. Wide voltage 9V ~ 24V input. Ethernet only works on ZLAN6842 Summary ZLAN6802 is 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 Digital Input(DI), Digital Output(DO), Analog Quantity Input(AI). 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. ZLAN6802 support communication method of RS485. 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 set. Feature 1) 8 channels digital quantity input: Support passive switch value (dry contact) and active level (wet contact). 2) 8 channels digital quantity output: The output type is 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, can demonstrate IO control and AI data acquisition for devices. 6) Can provide complete RS485 control instructions, convenient for integrated development of engineer.
