Technical Overview
The ADV151-P03/D5A00 is a high-reliability 32-channel digital input module for the Yokogawa CENTUM VP/CS 3000 platform. It is designed to process 24 V DC signals from field switches and sensors, with optical isolation to protect the system backplane from electrical transients.
The -P03 suffix provides advanced pushbutton edge-counting logic, while the /D5A00 option includes a factory-installed ATD5A-00 KS cable interface adapter for streamlined cabinet wiring. This module supports dual-redundant configurations, making it ideal for critical process monitoring and interlock systems.

Field Deployment and Use Cases
-
Control Room Pushbuttons: Captures momentary operator inputs reliably under high system load.
-
Redundant Safety Logic: Dual-redundant operation ensures continuous process visibility in critical interlocks.
-
High-Speed Discrete Monitoring: Monitors limit switches, motor run signals, and level transmitters in petrochemical, pharmaceutical, and utility applications.
Technical FAQ
What is the benefit of the /D5A00 option?
It includes the ATD5A-00 KS cable adapter, consolidating 32 channels into a single cable. This reduces terminal block space and simplifies cabinet wiring.
Can this module be used for Sequence of Events (SOE) recording?
The -P03 version is optimized for pushbutton/status inputs. For millisecond-precision SOE, verify the ADV151 series with the specific SOE suffix codes and software version compatibility.
Does the module supply power to the inputs?
No. The field-side 24 V DC loop requires an external power source. The 500 mA rating refers only to the power drawn from the DCS internal bus.
