Yokogawa ASS9562DK-00 – High-Precision Analog Input Module | CENTUM DCS Series
Engineering Background
The Yokogawa ASS9562DK-00 is a field-proven analog input module engineered for integration within Yokogawa’s CENTUM distributed control system (DCS) architecture. Designed to meet the rigorous demands of continuous process industries, this module delivers reliable, high-resolution signal acquisition from field instrumentation including transmitters, sensors, and transducers operating across standard analog ranges.
Product Positioning
As a core I/O component within the CENTUM platform, the ASS9562DK-00 serves as the critical interface between field devices and the process control network. It is the preferred choice for engineers specifying replacement or expansion I/O in refinery, chemical, power generation, and utility control systems where signal integrity and system uptime are non-negotiable.

- High Signal Fidelity: Precision A/D conversion minimizes measurement error across the full operating range, critical for PID loop stability
- Galvanic Isolation: Channel isolation protects the control network from field-side ground loops and transient surges
- Hot-Swap Capable: Supports online module replacement in CENTUM redundant configurations, eliminating planned downtime
- Long-Term Availability: Konmask maintains stock of legacy and current-generation Yokogawa I/O modules to support plant lifecycle management
System Architecture & Signal Flow
The ASS9562DK-00 mounts directly into a CENTUM I/O module rack (FIO or RIO node). Field wiring terminates at the associated terminal board or marshalling cabinet. Analog signals are conditioned, isolated, and digitized within the module before transmission over the CENTUM internal bus to the Field Control Station (FCS). The FCS processes the engineering-unit values and makes them available to the HIS (Human Interface Station) and historian in real time.
Typical Signal Path: Field Transmitter → Terminal Board → ASS9562DK-00 AI Module → CENTUM Bus → FCS → HIS / Historian
