ADV151-P13/D5A00

The Yokogawa ADV151-P13/D5A00 is a 32-channel, 24 V DC isolated digital input module for receiving ON/OFF signals from field contacts and pushbuttons. It supports pushbutton input counting and uses the ATD5A-00 KS cable interface adapter for field signal connection. The module is designed to transfer discrete input states to the control system for monitoring and event processing.

Input Functions and Signal Processing

The ADV151 receives discrete field signals and converts their electrical states into digital input information for the control system. Its 32 isolated channels allow multiple field contacts to be monitored through one module.

The input thresholds distinguish valid ON and OFF states. Signals between the specified ON and OFF limits should be evaluated against the module's input characteristics rather than treated as guaranteed switching states.

Pushbutton Input and Counting

The -P suffix identifies the pushbutton input function. This function detects pushbutton signal transitions and counts input edges, making it suitable for applications where discrete operator actions need to be registered rather than monitored only as steady ON/OFF states.

The specified pushbutton input characteristics include a minimum ON detection time of 20 ms and a maximum ON/OFF cycle frequency of 25 Hz. These limits should be considered when selecting field pushbuttons and configuring input signals.

Isolation and Electrical Protection

Electrical isolation separates the field input circuits from the system side. The published ADV151 specifications include the following withstand voltage ratings:

• Between input signal and system: 2 kV AC for 1 minute.
• Between commons: 500 V AC for 1 minute, with a common for every 16 channels.

The maximum allowable input voltage is 30.0 V DC. Field signal voltage should remain within the specified operating limits to ensure correct ON/OFF detection.

Connection Configuration

The /D5A00 option specifies the KS cable interface adapter ATD5A-00 for the 32-channel digital input module. It provides the interface between the module and the dedicated field connection cable.

The adapter configuration should be checked against the installed cabinet wiring and cable arrangement when replacing an existing module. The adapter designation is part of the complete ordering configuration and should not be omitted when identifying the replacement unit.

Frequently Asked Questions

Q: How many field signals can the ADV151-P13/D5A00 monitor?

A: It supports 32 digital input channels. Each channel receives a discrete 24 V DC field signal for ON/OFF status monitoring or pushbutton input processing.

Q: What is the difference between status input and pushbutton input?

A: Status input detects the ON/OFF state of a field contact. Pushbutton input additionally supports edge counting, allowing individual button operations to be registered. The pushbutton function has a minimum ON detection time of 20 ms.

Q: Which connection adapter is specified for this model?

A: The /D5A00 ordering option specifies the ATD5A-00 KS Cable Interface Adapter for 32-channel digital input connections.
