PLC - RS232/RS485 Serial Port
PLC - Programmable logic controller with RS232/RS485 Serial Ports for Industrial IoT installations and data management. PLC is a small rack-mounted modular device with wide range inputs and outputs (I/O), integrated with the Raspberry Pi Compute Module processor, networked to other PLC and SCADA systems.
PLC is designed designed for many arrangements of digital and analog I/O, wired and wireless interfaces extended temperature ranges for industrial applications. Programs to control machine operation are stored eMMC flash memory used for instructions and various functions.
