Product description
DM-4180D is a 16-channel isolated digital / switching acquisition module, which can be widely used in signal acquisition and monitoring of industrial field equipment. It has 16-channel isolated digital inputs, and 1 ~ 8-channel digital inputs have technical functions. Each channel of DI0 ~ DI7 has a 16-bit counter, which can measure the switching pulses within 200HZ. The communication interface adopts RS-485 interface and supports the standard MODBUS-RTU protocol. It can directly connect with configuration software, PLC, and DCS industrial control touch screen.

3. Working power: DC9 ~ 30V less than 3 W
Module indicator definition
1. POWER: Power status indicator, steady light indicates normal power supply
2. COMM: RS-485 interface communication instruction, flashing means the module is sending and receiving data
3. DI0 ~ DI15: Digital input indication, when lit, there is input for switching value.
Module register address description
1. 10001 ~ 10016: switch input register address (1X area)
MODBUS register addresses 10001 ~ 10016 are decimal addresses, which means that the hexadecimal address using the 02 function code is 0x0000 ~ 0x000F.
