8A2690240600 Finder Arduino Programmable Expansion Module

Why Choose the Finder 8A.26.9.024.0600 OPTA Expansion Module (Analogue Version)

The Finder 8A.26.9.024.0600 is an OPTA expansion module for analogue-heavy control tasks. It adds six analogue inputs (0-10 V, 4-20 mA or PT100 3-wire), two analogue outputs (0-10 V or 4-20 mA) and four PWM outputs, connecting to an OPTA main unit via the AUX port to extend capability without changing your CPU.
