ADV151-E63/D6A00

The Yokogawa ADV151-E63/D6A00 is a 32-channel isolated digital input module designed to receive 24 V DC ON/OFF signals from field devices. It supports status detection and Sequence of Events (SOE) capture, allowing the control system to monitor discrete signal changes and record event information. The E63 configuration includes a status display, ISA Standard G3 option and extended operating temperature option.

Functional Description

The ADV151-E receives discrete signals from field devices and converts their ON/OFF states into digital input information for the control system. Its 32 input channels support both sink and source signal configurations, with a rated input voltage of 24 V DC.

The module provides three input functions:

• Status Input: Detects the ON/OFF state of field signals for process monitoring and control logic.
• Pushbutton Input: Counts pushbutton signal edges, supporting applications that require discrete pulse or operation counting.
• SOE Input: Captures Sequence of Events data for recording changes in field signal states and supporting event analysis.

The SOE function is specific to the ADV151-E version. Its use requires the corresponding SOE system configuration.

Electrical Input Characteristics

The module recognizes an input voltage of 18 to 26.4 V DC as ON and 5.0 V DC or less as OFF. The input current is 4.1 mA +/-20% per channel at the rated voltage.

The input response time for status detection is 8 ms or less. For pushbutton input, the minimum ON detection time is 20 ms, with a maximum ON/OFF cycle of 25 Hz.

The input channels share a common connection every 16 channels. All 24 V DC input signals connected to the module must have the same polarity. This condition should be considered when designing field wiring.

Status Display and Environmental Configuration

The E63 suffix configuration includes a status display for visual channel monitoring and an ISA Standard G3 option with an extended operating temperature range of -20 to 70 deg C.

The G3 option is intended for environments with corrosive gas exposure. The 6 configuration indicates a status display without explosion protection. Therefore, this version should not be treated as an explosion-protected module.

System Configuration and Installation Considerations

The ADV151-E belongs to Yokogawa's FIO digital I/O module family. The FIO architecture supports installation in designated ESB Bus Node Units and Field Control Units.

The following configuration restrictions and electrical conditions are relevant:

• The ADV151-E cannot be installed in an ER Bus Node Unit.
• The module supports dual-redundant input configurations when used within a supported system architecture.
• All 24 V DC input signals connected to the module must have the same polarity.
• Withstanding voltage between input signal and system depends on the external connection method. The dedicated cable specification is 500 V AC, while the MIL connector cable specification depends on the cable's electrical characteristics.

Frequently Asked Questions

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

A: The ADV151-E provides SOE capture functionality, while the ADV151-P provides a pushbutton input function. Both versions support 32-channel, 24 V DC digital input operation.

Q: Can ADV151-E be installed in an ER Bus Node Unit?

A: No. Yokogawa specifies that ADV151-E cannot be installed in an ER Bus Node Unit. The applicable FIO node configuration must be checked before installation.

Q: What should be checked when connecting field signals to ADV151-E?

A: Verify the 24 V DC signal polarity, ON/OFF voltage thresholds and common grouping. The module shares a common connection every 16 channels, so all connected input signals must have the same polarity.
