I ordered an Arduino Opta (RS485 version) and it has arrived – stay tuned for upcoming posts!
In the meantime, I’ve updated my initial review as it has been confirmed that the digital inputs support 24VDC. Programming support for IEC 61131-3 PLC languages has also been clarified (no MacOS support sadly).
|Partnership with Finder
|DIN rail mount
|Analogue inputs use 0-10VDC, not “standard” 4-20mA
|Can programming be done over Ethernet?
|IEC 61131-3 PLC language support
|I/O expansion options?
(What does the “AUX” port do?)
|Digital inputs support 24VDC (see here)
|Beefy relay outputs with dedicated commons
|Modbus-TCP and Modbus-RTU support
|Input power supply is 12-24VDC
|-20 °C to +50 °C temperature operating range
