Type:Logic ICs
Condition:New

Basic functions:Support standard MODBUS devices such as text, touch screen, PLC, etc.

Eight analog outputs (4-20mA, 0-5V, 0-10V) and eight 10 bit outputs with an accuracy of 0.1%.
1-way standard 485 communication port, isolated communication (supporting modbus-RTU protocol free port communication protocol)

Code Function Support Function Code:

Function code	Definition	Operations (binary)

0x030x04	Read register data	Read data from one or more registers

0x06	Write single path register	Write a set of binary data into a single register
0x10	Write multiplexer register	Write multiple sets of binary data into multiple registers
