ADV151-E63/D5A00

The Yokogawa ADV151-E63/D5A00 is a 32-channel isolated digital input module designed to receive 24 V DC ON/OFF signals in the Yokogawa Field Control System (FIO). It features Sequence of Events (SOE) capture, channel status indication, and an ISA Standard G3 option. The /D5A00 configuration includes a KS cable interface adapter for connecting the digital input signals.

Digital Input Operation and SOE Capture

The ADV151 receives field ON/OFF signals and converts them into digital status information for the control system. Its 32 input channels support both sink and source connections. Each channel can be used to monitor a field contact or voltage signal, subject to the specified input voltage and polarity requirements.

The SOE (Sequence of Events) function captures input event data for time-sequence analysis. This allows control-system engineers to examine the order of digital state changes when investigating equipment trips, interlocks, and process events. SOE operation has specific node installation restrictions and should be checked against the applicable FIO system documentation.

Model Configuration and Ordering Codes

The complete ordering code identifies the input function, display configuration, environmental option, and field connection arrangement:

Code	Specification
ADV151	32-channel, 24 V DC isolated digital input module
-E	With SOE capture
6	With status display; without explosion protection
3	ISA Standard G3 option and -20 to 70 deg C temperature option
/D5A00	KS cable interface adapter for 32-channel digital input, model ATD5A-00

The /D5A00 option provides the cable interface arrangement for field signal connection. It should be distinguished from the pressure-clamp terminal block options, which use different ordering codes.

Electrical Characteristics and Signal Isolation

The module accepts a nominal 24 V DC input signal. An input voltage of 18 to 26.4 V DC is recognized as ON, while 5.0 V DC or less is recognized as OFF. The specified input current is 4.1 mA +/-20% per channel.

Input isolation is specified at 2 kV AC for one minute between the input signal and system, and 500 V AC for one minute between commons. The commons are arranged in groups of 16 channels. All connected 24 V DC input signals must have the same polarity.

Installation and System Considerations

The ADV151-E includes an SOE capture function, but its installation location affects whether that function can be used. The manufacturer specifies that ADV151-E cannot be installed in an ER Bus Node Unit. SOE capture is available only when installed in an ESB Bus Node Unit or Optical ESB Bus Node Unit.

The ADV151 and ADV161 module families support dual-redundant configurations. However, redundancy suitability for a particular control-system arrangement should be checked against the applicable system configuration and installation documentation.

Frequently Asked Questions

Q: What is the difference between ADV151-E63 and ADV151-E63/D5A00?

A: Both codes identify the same 32-channel SOE-capable digital input module configuration. The /D5A00 suffix adds the KS cable interface adapter ATD5A-00 for field wiring.

Q: Can the ADV151-E63/D5A00 use SOE capture in any FIO node?

A: No. ADV151-E cannot be installed in an ER Bus Node Unit. Its SOE capture function is supported only in ESB Bus Node Units and Optical ESB Bus Node Units.

Q: Does the ADV151-E63 provide explosion protection?

A: No. The suffix code 6 specifies a version with status display and without explosion protection. The 3 code identifies the ISA Standard G3 and -20 to 70 deg C temperature options; it does not indicate an explosion-protection rating.
