Key Features
-
Fully configurable channels – Each of the 16 channels can be independently set as input or output for maximum flexibility
-
High electrical isolation – 500V isolation between channels suppresses common-mode interference in high-noise industrial environments
-
Hot-swappable design – Supports plug-and-play replacement, minimizing downtime for critical drive systems
Industry / Application
-
Steel and metal rolling mills – collecting limit switch feedback, emergency stop signals, and drive status for mill stand control
-
Mining and conveyors – interfacing with safety relays, belt alignment switches, and pull-cord stops
-
Cement and heavy industrial fans – providing control outputs for damper actuators and vibration monitoring inputs
-
Large pumps and compressors – enabling remote start/stop logic and process interlocking
