ZLAN6842 8 Channels Ethernet Remote IO support RS485 Ethernet Wifi and P2P communication

 is 8 channels remote IO controller launche by Shanghai ZLAN after ZLAN6042.
The controlle 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 after 4 channels support 4~20mA current input, the accuracy is 10 bits.
ZLAN6842 support 2 communication methods of Ethernet, RS485.

ZLAN6842: it’s an IO controller using Ethernet to control,
the usually using communication protocol is Modbus TCP protocol,
If want to control through Modbus RTU protocol,
set module converting protocol to “No”, by using TCP to send Modbus RTU protocol can do the control.
