DAM-3012D/DAM-3013D 14/16-channel isolated digital input module Dry / Wet Contact data acquisition module RS485 communication interface ModbusRTU protocol

Working principle
The upper computer sends MODBUS RTU protocol instructions to the DAM terminal through RS232/RS485/USB/RJ45/WIFI to achieve data acquisition.
