AAV141-S03/K4A00

The Yokogawa AAV141-S03/K4A00 is a 16-channel analog input module designed to receive 1-5 V DC signals from field instruments and convert them into internal process data for a Yokogawa distributed control system. It uses non-isolated input channels and includes the KS Cable Interface Adapter option, ATK4A-00. The S03 configuration also specifies ISA Standard G3 and an extended temperature option.

Functional Description

The AAV141 receives standardized voltage signals from field transmitters and other analog signal sources. Each of its 16 input channels acquires a 1-5 V DC signal for processing by the control system.

The non-isolated input design means that individual channels do not provide galvanic isolation from one another. Signal-source grounding, common-mode voltage and external isolation requirements should therefore be considered during system design.

Input Characteristics

The 1-5 V DC input range is intended for standardized voltage signals. The module has an input resistance of at least 1 MOhm during normal operation, reducing the loading effect on connected signal sources.

The specified accuracy is +/-4 mV, with temperature drift of +/-4 mV per 10 deg C. The allowable common-mode voltage is +/-1 V or less. These limits should be considered when checking transmitter output accuracy and field wiring conditions.

Model Configuration

The complete ordering code identifies the module and its connection configuration:

• AAV141: 1-5 V DC, 16-channel, non-isolated analog input module.
• -S: Standard type.
• 0: No explosion protection.
• 3: ISA Standard G3 option and temperature option (-20 to 70 deg C).
• /K4A00: KS Cable Interface Adapter, model ATK4A-00.

The /K4A00 option identifies the cable interface configuration rather than a different input signal type. The corresponding connection hardware should be checked against the existing system wiring arrangement before replacement.

Frequently Asked Questions

Q: What is the difference between AAV141 and AAI141?

A: AAV141 accepts 1-5 V DC voltage signals, whereas AAI141 accepts 4-20 mA DC current signals. Both models provide 16 non-isolated input channels, but they are designed for different field signal types.

Q: Does the AAV141-S03/K4A00 support intrinsically safe field wiring?

A: The specified AAV141 configuration is a non-isolated input module without explosion protection. Intrinsically safe applications require an appropriate external isolation barrier and a separately verified system design.

Q: What is the function of the K4A00 option?

A: K4A00 specifies the KS Cable Interface Adapter configuration, associated with adapter model ATK4A-00. It identifies the signal connection arrangement and should be checked when matching replacement hardware to existing cabling.
