MTL 8121‑DI‑DC‑16‑Channel Digital Input Module

Product Overview

8121‑DI‑DC belongs to MTL8000 remote I/O series, a 16‑channel non‑isolated 24 VDC digital input module powered by backplane bus. It collects discrete on‑off status signals from field sensors and switches, transmitting digital status data to host safety or DCS controllers. This module solves large‑volume discrete‑signal acquisition demands for hazardous‑area automation systems, simplifying field‑wiring layout for multi‑point digital monitoring.
