ABB DI620 is a digital input module.The following is a detailed introduction to it:
1.Main features
Function:The main function of the DI620 module is to collect digital signals from remote sites to the computer.It uses the RS 485 bus as a data communication line,provides a digital quantity to 485 function,can simultaneously input multiple digital quantities into the module,and transmit them to the computer through the RS-485 bus.
Communication interface:Using the RS-485 interface,multiple modules can be combined to transmit more digital quantity signals,and dispersed configuration on the 485 line.Distinguished by address code,it can be directly connected to the configuration software of the MODBUS RTU protocol.
2.Application field
The DI620 module plays an important role in industrial automation,especially when multiple sensors or actuators need to be monitored.By using digital input modules,engineers and operators can have a more comprehensive understanding of the system status and achieve more precise control and adjustment.
