ADV151-P50/B5S00

The Yokogawa ADV151-P50/B5S00 is a 32-channel digital input module designed to receive 24 V DC discrete signals in a Yokogawa control system. It belongs to the ADV151 digital input module family and is specified with isolated input channels, pushbutton input functionality, and a pressure clamp terminal block (ATB5S-00). The supplied configuration also specifies no status display and no explosion protection.

Digital Input Function

The module receives field ON/OFF signals and converts their electrical states into digital input information for the control system. Its 32 isolated input channels support 24 V DC sink/source signals. The isolation design provides electrical separation between field input signals and the system, as well as between channel groups.

The -P suffix identifies the pushbutton input function. In addition to detecting normal ON/OFF status, this configuration supports pushbutton edge counting. This allows the control system to register discrete button operations rather than relying only on the maintained signal state.

Input Signal Characteristics

The input voltage thresholds define how field signals are interpreted:

• Input ON voltage: 18 to 26.4 V DC.
• Input OFF voltage: 5.0 V DC or less.
• Input current: 4.1 mA +/-20% per channel at rated voltage.
• Maximum allowable input voltage: 30.0 V DC.
• Input response time: 8 ms or less for status input.
• Minimum ON detection time: 20 ms for pushbutton input.
• Maximum ON/OFF cycle: 25 Hz for pushbutton input.

The separation between the ON and OFF voltage thresholds provides a defined switching region. Field signals should remain within the specified input limits to ensure correct state detection.

Terminal Connection

The /B5S00 option specifies the ATB5S-00 pressure clamp terminal block for digital input connections. This configuration provides the field wiring interface for the module and distinguishes it from versions ordered with dedicated cable or other terminal arrangements.

The module has common connections for every 16 channels. All 24 V DC input signals connected to the module must use the same polarity.

Model and Configuration Breakdown

Code	Specification
ADV151	32-channel, 24 V DC isolated digital input module
-P	With pushbutton input
5	Without status display; without explosion protection
0	Basic type
/B5S00	Pressure clamp terminal block for digital input, ATB5S-00

The complete ordering number ADV151-P50/B5S00 identifies the module and its specified terminal configuration. The /B5S00 option should be checked when replacing an existing module because the terminal connection arrangement is part of the ordered configuration.

Frequently Asked Questions

Q: What is the difference between ADV151-P50/B5S00 and a standard ADV151 digital input module?

A: This ordering configuration includes the pushbutton input function, no status display, no explosion protection, and the ATB5S-00 pressure clamp terminal block. The complete suffix and option code should be checked when selecting a replacement.

Q: Can ADV151-P50/B5S00 detect momentary pushbutton operations?

A: Yes. The -P configuration supports pushbutton edge counting. The specified minimum ON detection time is 20 ms, with a maximum ON/OFF cycle of 25 Hz.

Q: What should be checked when connecting 24 V DC field signals?

A: Verify that the input voltage meets the specified ON/OFF thresholds and does not exceed 30.0 V DC. The module uses a common connection for every 16 channels, and all connected input signals must have the same polarity.
