Digital Input Operation

The ADV151-P50/D5A00 receives discrete voltage signals from external devices and converts their electrical states into digital input information for the control system. Its 32 input channels allow multiple field signals to be monitored through one module.

The module supports both sink and source input configurations. The ON-state voltage range is 18 to 26.4 V DC, while an input voltage of 5.0 V DC or less is recognized as OFF. These thresholds provide defined electrical conditions for field signal recognition.

Input Protection and Electrical Isolation

The module specifies a withstand voltage of 2 kV AC for one minute between the input signal and the system. The withstand voltage between commons is 500 V AC for one minute, with a separate common for each group of 16 channels.

The maximum allowable input voltage is 30.0 V DC. Field signal voltages must remain within this limit to avoid exceeding the specified input rating.

Connection and Cable Interface

The ADV151-P50/D5A00 supports several external connection methods:

• Pressure clamp terminal connection.
• Dedicated cable connection using AKB331.
• MIL connector cable connection.
• KS Cable Interface Adapter ATD5A-00 for 32-channel digital input connections.

The /D5A00 option identifies the configuration supplied with the KS Cable Interface Adapter, model ATD5A-00. This adapter should be considered when checking the field wiring arrangement and replacement configuration.

Model Suffix and Configuration

The supplied ordering information identifies the following configuration details:

Code	Description
P	With pushbutton input
5	Without status display; with no explosion protection
0	Basic type
/D5A00	With KS Cable Interface Adapter for 32-channel digital input, model ATD5A-00

These configuration details are relevant when matching the module against an existing installation. In particular, the pushbutton input option, status display configuration, and cable interface adapter should be checked before ordering a replacement.

Frequently Asked Questions

Q: How many digital input channels does the ADV151-P50/D5A00 provide?

A: It provides 32 digital input channels, operating with a rated input voltage of 24 V DC. The input configuration supports both sink and source arrangements.

Q: What is the function of the /D5A00 option?

A: The /D5A00 option specifies the KS Cable Interface Adapter for 32-channel digital input connections, model ATD5A-00. It should be included in configuration checks when replacing an existing unit.

Q: What are the electrical isolation ratings of this module?

A: The specified withstand voltage is 2 kV AC for one minute between input signal and system, and 500 V AC for one minute between commons. The commons are arranged in groups of 16 channels.
