ADV151-E50/B5S00

The Yokogawa ADV151-E50/B5S00 is a 32-channel digital input module designed to receive 24 V DC ON/OFF signals from field devices and transfer their status to a control system. It features Sequence of Events (SOE) capture for event recording and a pressure clamp terminal block for field signal connections. The module provides input signal isolation and supports both sink and source input configurations.

Functional Description

The ADV151-E50 receives discrete voltage signals and detects changes between ON and OFF states. It is suitable for monitoring field contacts and 24 V DC status signals, allowing the control system to acquire equipment operating states and process discrete events.

The SOE capture function records event data for sequence-of-events monitoring. This function is specific to the ADV151-E configuration and distinguishes it from the ADV151-P version, which supports pushbutton input instead.

Input Signal Characteristics

The module accepts 24 V DC input signals in either sink or source configuration. Its ON-state detection range is 18 to 26.4 V DC, while signals at 5.0 V DC or below are recognized as OFF.

The input current is 4.1 mA +/- 20% per channel at the rated voltage. The maximum allowable input voltage is 30.0 V DC. For status input operation, the specified response time is 8 ms or less.

Electrical Isolation and Wiring

The input circuit provides isolation between the field input signals and the control system. The specified withstand voltage is 2 kV AC for one minute between input signals and the system, and 500 V AC for one minute between commons.

The module uses a common connection for every 16 channels. All connected 24 V DC input signals must have the same polarity. These requirements should be considered when grouping field signals and designing the external wiring.

Terminal Block Configuration

The /B5S00 option specifies a pressure clamp terminal block for digital input, identified by Yokogawa as ATB5S-00. This configuration provides the terminal interface for connecting field wiring to the module.

The terminal block option should be checked when replacing an existing module, particularly where the installed field wiring and terminal arrangement must be retained.

Model and Ordering Code Identification

The complete ordering designation identifies the input module, its functional configuration and its terminal block option.

Code	Description
ADV151	32-channel, 24 V DC isolated digital input module
-E	With SOE capture
5	Without status display; without explosion protection
0	Basic type
/B5S00	Pressure clamp terminal block for digital input (ATB5S-00)

The -E and 5 codes have different functions in the ordering designation. The former identifies SOE capture, while the latter specifies the status display and explosion protection configuration.

Frequently Asked Questions

Q: What is the difference between ADV151-E and ADV151-P?

A: The ADV151-E supports SOE input for capturing sequence-of-events data, whereas the ADV151-P supports pushbutton input for counting pushbutton edges. These are different input functions and should not be treated as interchangeable configurations.

Q: What terminal block is specified for ADV151-E50/B5S00?

A: The /B5S00 option specifies the ATB5S-00 pressure clamp terminal block for digital input. This should be considered when checking the terminal arrangement for replacement or maintenance.

Q: Can all 32 input channels use different signal polarities?

A: No. Yokogawa specifies a common connection for every 16 channels, and all connected 24 V DC input signals must have the same polarity. The field wiring arrangement must comply with this requirement.
