ADV161-P00 Yokogawa Digital Input Module

Overview

Configured for 24 VDC status signal acquisition in the CENTUM VP FIO system, the Yokogawa ADV161-P00 (ADV161 Digital Input Module) provides direct electrical input processing for 64-channel isolated digital signals.

Hardware Specifications

Channel Isolation and Digital Signal Processing

The Yokogawa ADV161-P00 performs digital signal acquisition through isolated input channels within the FIO architecture. Therefore, the module separates field input circuits from system circuits through electrical isolation.

The module supports multiple digital point modes including status input and pushbutton input assignments. Additionally, it supports status output, pulse width output, and time-proportioning ON/OFF output configurations according to CENTUM VP digital module point mode definitions.

The input design uses a 24 VDC field signal interface with defined ON and OFF voltage thresholds. Furthermore, the 16-channel common grouping provides controlled wiring organization for distributed digital field connections.

Process Control Interface Characteristics

As a Yokogawa CENTUM VP FIO component, the ADV161-P00 operates within a process control I/O environment. The module supports channel-to-channel isolation concepts used in Yokogawa distributed I/O systems, reducing interference between independent field signal groups.

The isolated input structure allows connection of external contact signals and digital devices while maintaining separation between field wiring and controller-side circuits. Therefore, correct grounding and shielding practices remain required during installation.

Frequently Asked Questions

Q: How many digital input channels does the ADV161-P00 provide?
A: The ADV161-P00 provides 64 isolated digital input channels with a rated input voltage of 24 VDC.

Q: What input voltage levels define the ON and OFF states?
A: The module recognizes an ON state from 20 to 26.4 VDC and an OFF state at 5.0 VDC or less.

Q: Does the ADV161-P00 support different digital point assignments?
A: Yes. The module supports point modes including status input, pushbutton input, status output, pulse width output, and time-proportioning ON/OFF output functions.

Field Installation Guidelines

• Install the ADV161-P00 only within the compatible Yokogawa FIO node configuration specified for CENTUM VP systems.
• Verify field wiring polarity before applying 24 VDC input signals to the module terminals.
• Separate digital signal cables from high-voltage power cables to reduce electrical interference.
• Connect cable shields according to the plant grounding standard and avoid creating unintended ground loops.
• Confirm common grouping requirements because the module uses common separation based on 16-channel sections.
• Check insulation resistance and field signal voltage levels before system commissioning.
