This module instantly adds 16 versatile inputs (analog or digital) and 8 robust relay outputs to your setup. Whether you are using the classic Arduino IDE or the professional Arduino PLC IDE (supporting Ladder, FBD, and more), these new I/Os are managed transparently, allowing you to leverage the full power of the Arduino Pro environment.
Massive I/O Capacity: Manage up to 16 signals (0-24V) and switch up to 8 loads of 6A at 230V.
Maximum Scalability: Connect up to 4 modules in a daisy-chain configuration to a single Opta base unit (Lite, RS485, or WiFi) for an impressive total of I/O ports.
Industrial Grade: Born from the partnership between Arduino and Finder, this system combines industrial-grade reliability with the legendary flexibility of Arduino.
Pro Installation: A compact, rugged design specifically engineered for quick and clean DIN rail mounting.

The Opta D1608E fits perfectly into your existing workflow:
- Arduino IDE 2.0 : For smooth C++ programming.
- Arduino PLC IDE: Perfect for professionals using IEC 61131-3 languages (LD, FBD, ST, etc.).
- Arduino Cloud : For secure remote monitoring and global control of your hardware.
Automated Production Lines: Control of complex machinery and conveyors.
Real-time Monitoring: Tracking production metrics and detecting anomalies instantly.
Predictive Maintenance: Analyzing fine analog sensor data to anticipate and prevent system failures.
Note: This expansion module requires an Arduino Opta base unit (not included) to operate. A 12-24VDC power supply must be connected to the screw terminals.
