ADV151-E63

The Yokogawa ADV151-E63 is a 32-channel isolated digital input module designed to receive 24 V DC ON/OFF signals in the FIO (Fieldnetwork I/O) architecture. It supports Sequence of Events (SOE) data capture, allowing discrete input transitions to be recorded for event analysis. The E63 configuration includes a status display and the ISA Standard G3 environmental option with an extended temperature range.

Functional Description

The ADV151-E63 acquires discrete field signals and transfers their ON/OFF states to the control system. Its 32 input channels accept 24 V DC signals in either sink or source configurations.

The module supports three input functions:

• Status input: Detects the ON/OFF state of field signals.
• SOE input: Captures Sequence of Events data for recording and analyzing discrete signal transitions.
• Pushbutton input: Supports edge counting, subject to the applicable model functionality.

SOE capture is particularly relevant when reconstructing the sequence of discrete events during process disturbances or equipment trips.

Input Signal Characteristics

The input ON threshold is 18 to 26.4 V DC, while an input voltage of 5.0 V DC or less is recognized as OFF. The rated input current is 4.1 mA +/-20% per channel.

The 32 channels are arranged in groups sharing a common every 16 channels. All 24 V DC input signals connected to the module must have the same polarity. This wiring condition should be considered when grouping field contacts and voltage-fed signals.

Isolation and Input Response

The module provides electrical withstand capability of 2 kV AC for one minute between the input signal and system. The withstand voltage between channel-group commons is 500 V AC for one minute.

For status input, the specified response time is 8 ms or less. The pushbutton input function has a minimum ON detection time of 20 ms and a maximum ON/OFF cycle of 25 Hz. These timing characteristics should be considered when selecting the module for event detection or pulse-counting signals.

Model Configuration and Environmental Option

The model code identifies the module as an ADV151 digital input unit with SOE capture. The -E suffix specifies SOE capture, 6 specifies a status display without explosion protection, and 3 specifies the ISA Standard G3 option with a temperature range of -20 to 70 deg C.

The status display provides a local indication for checking module status. The G3 option is relevant when selecting I/O hardware for environments where corrosive gas exposure is a design consideration.

System Installation and Connection

The ADV151-E version has an important installation restriction: it cannot be installed in an ER Bus Node Unit. Its SOE capture function is available only when installed in an ESB Bus Node Unit or an Optical ESB Bus Node Unit.

Supported external connection arrangements include pressure-clamp terminals, the dedicated AKB331 cable, and MIL connector cables. The actual connection arrangement must match the selected terminal or cable interface.

Frequently Asked Questions

Q: Does the ADV151-E63 support Sequence of Events recording?

A: Yes. The ADV151-E63 includes the SOE capture function. It captures input events for transfer to the Yokogawa SOE system, where time-stamped events can be stored and displayed chronologically.

Q: Can the ADV151-E63 be installed in an ER Bus Node Unit?

A: No. The ADV151-E version is not permitted in ER Bus Node Units. Its SOE capture function is supported when installed in an ESB Bus Node Unit or Optical ESB Bus Node Unit.

Q: What should be considered when wiring the 32 input channels?

A: The channels share a common every 16 channels. All connected 24 V DC input signals must have the same polarity. The selected terminal or cable interface must also match the installation configuration.
