Description
The X‑432‑I is an all‑in‑one Ethernet PLC delivering 38 onboard I/O—16 relays, 18 digital inputs, 4 analog inputs, and support for up to 16 DS18B20 temperature sensors. Powered by 9–28 V DC, it combines a no‑code logic builder, peer‑to‑peer networking, and a customizable web dashboard to control and monitor complex processes locally or remotely. Ruggedly built for wall or DIN‑rail mounting, the X‑432‑I excels in applications from greenhouse climate control to building automation and wastewater treatment.
