Arduino Opta RS485 PROGRAMMABLE LOGIC RELAY (PLR) RS485+ETHERNET

The original Arduino® Opta RS485 (AFX00001) is a programmable 4-channel logic relay that can be controlled via Ethernet or RS485 bus. Programming is done using the Arduino C++ language or a custom PLC graphical programming tool compliant with the IEC 61131-3 standards. A PLC IDE license is included with the device. Opta meets the requirements of the X.509 standard and is equipped with a dedicated cryptographic chip, making it well-suited for industrial IoT applications requiring high security.
