Opta Expansions

Arduino's Opta Digital Expansion multiplies system capabilities with 16 programmable inputs for connecting digital sensors and eight more relays to operate machines.

Opta digital expansions are available in two variants:

• Arduino Pro Opta Ext D1608E: 16 programmable voltage inputs with 8 electromechanical relays, 250 V_AC 6 A
• Arduino Pro Opta Ext D1608S: 16 programmable voltage inputs with 8 solid-state relays, 24 V_DC 2 A

Quickly put them to work, managing the I/Os from the Opta base unit seamlessly and taking advantage of the open and widely known Arduino ecosystem or PLC IDE IEC 61131-3 programming environment.

Analog Expansion

Enhance Arduino Opta’s real-time control, monitoring, and predictive maintenance applications with the Arduino Pro Opta Ext A0602.

Snap on the Opta Analog Expansion and extend system capabilities with the addition of six programmable inputs for connecting analog sensors, reading voltages (0 V to 10 V), current (0/4 mA to 20 mA), or temperature through RTD PT100 sensors.

Get an advantage with the flexibility of two analog outputs, programmable in voltage (0 V to 10 V) or current (0/4 mA to 20 mA), plus four PWM digital outputs.
