Arduino Pro Opta Ext D1608S
The snap-on expansion module to enhance Arduino Opta’s applications with the addition of 16 programmable voltage inputs and 8 solid-state relays.
Overview
Arduino Pro Opta Ext D1608S enhances your Arduino Opta’s real-time control, monitoring and predictive maintenance applications with the addition of 16 programmable voltage inputs and 8 solid-state relays 24 VDC 2A.
Just snap on the module to extend your system’s capabilities flexibly and quickly, and manage the new I/Os from the Opta base unit seamlessly, taking advantage of the open and widely known Arduino ecosystem or PLC IDE IEC 61131-3 programming environment.
Key benefits:
- Flexible inputs: 16 new inputs for your applications per each expansion added, programmable as digital 0-24 VDC or analog 0-10 V.
- Powerful outputs: 8 solid-state relays offering 24 VDC for 2A each.
- Up to 5 snap-on modules can be managed to multiply and mix a set of I/Os with seamless detection: snap them right next to your Opta base module and use the I/Os as native Opta resources.
- Extend your hardware capabilities while keeping programming accessible, by using the Arduino IDE with its wide range of ready-to-use sketches, tutorials and libraries.
- Put your new I/Os easily to work with the PLC IDE for IEC 61131-3 PLC languages, taking advantage of its low-code approach and pre-mapped resources.
- Extend the Opta’s benefits of real-time remote monitoring via intuitive Arduino Cloud dashboards and secure communication to a wider set of connected devices.
- Reliable by design, thanks to industrial certifications and Finder’s expertise in electronic devices.
- Easy DIN rail installation.
Applications
Opta’s digital expansions are ideal to increase the number of real-time control points in the manufacturing sector and in any building automation project.
The Opta Ecosystem is compatible with all major cloud providers – but choosing the simplicity of Arduino Cloud can really make a difference, for anyone who wants to build, customize and remotely manage their own dashboards.

… between the Rev2 and the previous version of the MKR IoT Carrier. Here are the main ones. Some sensors have changed: The humidity sensor (HTS221) and barometric pressure sensor (LP22HB) has been replaced with the BME688 sensor.The IMU (LSM6DS3) was replaced with LSM6DSOX. Following customer feedback some other components have been repositioned: Addition of a handy reset button90° rotation of the relay connectorsRepositioning of the light sensor (APDS-9960)Change of pins assigned to control the relays to pins 1 and 2Change grove connector assignment from pin A5 to A6 Do I have to change my sketch if I have been using the first revision of the MKR IoT Carrier? No — the MKR IoT Carrier library works with both revisions of the carrier. Just make sure to use the latest version of the library to ensure everything goes smoothly. Have more fun with the IoT The new MKR IoT Carrier Rev2 is the perfect tool to get started having fun with your own IoT projects, or to take your IoT tinkering to the next level. You don’t need a ton of experience, a bucket of expensive components, or endless hours of free time to build your own satisfying, useful IoT gadgets at home. Discover the MKR IoT Carrier Rev2
