Review: Deze modbus module werkt fantastisch. Werkt goed samen met een Siemens LOGO!8. De te downloaden software is slecht vertaald, de helft wordt in onleesbaar chinees getoond. Echter heeft de software geen toegevoegde waarde. De documentatie kan je downloaden op de website van EBYTE. Deze documentatie is voldoende duidelijk om instellingen in het holdingregister aan te passen en is de software overbodig. De ID kan worden ingesteld met dipswitches maar deze werken even anders dan in de documentatie staat. Als switch 1 op ON staat is het ID16. Voor de rest kom je er met de documentatie wel uit. Mooi product voor redelijke prijs.
Review: Should to know: the AIs are 0/4...20 mA current signal only. No 0...10 V possible as far I can see at the manufacturer's manual. Hardware quality seems flawless.

## Features

- MA01-AACX2240 supports the acquisition of 2-channel sensor switch input (DI) and 2-channel sensor analog input (AI), which is converted into serial port (RS485) and data is transmitted to configuration software or PLC. The serial port I/O networking module (also called "remote IO") that realizes the remote acquisition and control function by issuing commands through the serial port to control 4 relay switch outputs (DO).
- Support for modbus RTU protocols; Support for all types of configuration software / PLC / touch screen; RS485 Acquisition Control IO; DC 8to28V power supply;
- 2 switch input DI(dry node); 2 analog input AI(0 to 20mA/4 to 20mA); 4 switch output DO(relay); Switch input(DI)supports counting; Switch input(DI)supports rising, falling, level triggering;
- Switch output(DO)supports level mode, pulse mode, follow mode; Input acquisition port isolation protection;
- Communication Baud Rate1200 to115200(default 9600),supports custom settings; Support for 1to247 substations,5-bit dial switch can be set 1to31 address code, greater than 31 can be set by software

Il modulo EBYTE MA02-XXCX0080 si presenta come una soluzione interessante per chi necessita di un'interfaccia 8DO Modbus. La sua configurazione è relativamente semplice e l'integrazione in sistemi esistenti risulta generalmente fluida. Aree di Miglioramento: Documentazione: La documentazione fornita, sebbene sufficiente, potrebbe essere più dettagliata e comprensiva, soprattutto per utenti meno esperti.
