ADV151-P10 S2 | Digital Input Module | Yokogawa

Configured for 24 VDC digital signal acquisition in Yokogawa CENTUM CS and CENTUM VP systems, the Yokogawa ADV151-P10 S2 (ADV151 Digital Input Module) provides 32 input channels for status detection, pushbutton edge counting, and Sequence of Events (SOE) input data capture.

Hardware Specifications

Yokogawa DCS Digital Input Processing

The ADV151-P10 S2 accepts 24 VDC sink/source signals and processes each channel as a discrete input. Therefore, the module can detect standard ON/OFF states while maintaining defined voltage thresholds for input recognition.

The module also supports pushbutton input processing. It detects input edges with a minimum ON detection time of 20 ms and supports an ON/OFF cycle of up to 25 Hz.

For event monitoring, the module supports SOE input data capture. This function allows the connected DCS to process discrete signal state changes as event information.

The input signal and system circuits withstand 2 kV AC for 1 minute. In addition, the module provides 500 V AC withstand capability between commons, with one common assigned to every 16 channels.

Frequently Asked Questions

Q: What voltage does the ADV151-P10 S2 use for digital input signals?
A: The module uses a rated 24 VDC input. The specified ON range is 18 to 26.4 VDC, while 5.0 VDC or less represents the OFF condition.

Q: How many digital input channels does the ADV151-P10 S2 provide?
A: The module provides 32 digital input channels for status input, pushbutton input, and SOE input data capture.

Q: What connection methods does the module support?
A: The supplied specifications identify pressure clamp terminals, MIL connector cables, and the dedicated AKB331 cable as external connection methods.

Field Installation Guidelines

• Verify the module model and system compatibility before installation.
• Confirm that field input wiring matches the specified 24 VDC sink/source configuration.
• Keep digital signal wiring separated from high-voltage power and high-noise switching circuits where practical.
• Check input polarity and common connections before applying field power.
• Use the specified terminal, MIL connector cable, or dedicated AKB331 cable according to the installed connection arrangement.
• Maintain appropriate shield and grounding practices according to the cabinet and DCS installation design.
• Verify that the applied input voltage remains within the specified allowable range before commissioning.
• Check all 32 channels for correct ON/OFF recognition during functional testing.
• For pushbutton applications, verify that the connected signal satisfies the specified minimum ON detection time.
• For SOE applications, confirm field wiring continuity and event input behavior during system commissioning.
