Technical Overview
The ADV161-P00 is an ultra-high-density digital input module for the Yokogawa CENTUM VP / CS 3000 series. It provides 64 discrete input points in a single I/O slot, supporting 24 V DC signals (dry contact or voltage-driven). The module features pushbutton edge-counting logic and grouped isolation, making it ideal for high-density monitoring in large-scale process and utility applications.

Large-Scale Automation: High-density input consolidation for utility plants, refining, and petrochemical sites.
Technical FAQ
How does the 64-channel density affect wiring?
-
High-density layout eliminates front screw terminals. The module interfaces via KS cables to separate terminal boards (e.g., TEV series) for organized and manageable wiring.
Can the ADV161-P00 be used for Sequence of Events (SOE) recording?
-
The basic -P00 model supports status and pushbutton inputs. For millisecond-level SOE recording, SOE-specific ADV161 variants are recommended.
What is the advantage of sink/source compatibility?
-
The module can accept either NPN (sink) or PNP (source) inputs, allowing flexible integration with diverse field devices and international wiring standards.
