The Advantech MIC-2730 is a 16-channel isolated digital input module for industrial automation and data acquisition. It accepts dry contact and wet contact signals up to 30 VDC, with 2500 VDC isolation between channels to eliminate ground loop interference and transient voltage coupling. Configurable debounce filtering suppresses noise-induced false triggers. Built-in overvoltage and reverse polarity protection safeguard against field wiring faults. The module mounts on DIN rail in a ruggedized enclosure and connects via removable screw terminal blocks. It operates from 10 to 35 VDC supply voltage across industrial temperature ranges.
