Function & Positioning

The P0400QU is a 16‑channel digital output module that converts DCS control logic into dry contact/relay outputs for field actuators. It supports NO/NC relay contacts with configurable on‑delay/off‑delay timers and pulse output modes. Positioned as a cost‑effective, high‑density DO solution, it reduces wiring and cabinet space while providing reliable isolation and diagnostics for critical control and interlock circuits.
