Yokogawa AEA4D-06 Terminal Board

Hardware Specifications

Process Signal Termination and Isolation Considerations

The AEA4D-06 provides the physical termination point for analog channels associated with compatible Yokogawa modules. The board supports single-module and dual-redundant configurations.

For process instrumentation, installers should route analog signal wiring separately from high-voltage power and high-current switching conductors. Where shielded cable is specified by the system design, terminate the shield according to the Yokogawa installation documentation and the site grounding scheme.

The supplied specifications do not identify a specific analog signal range, such as 4-20 mA, or a channel-to-channel isolation rating. Therefore, these values should be taken from the associated I/O module documentation rather than assigned to the terminal board.

Frequently Asked Questions

Q: How many analog channels does the AEA4D-06 support?
A: The supplied data identifies the AEA4D-06 as a 16-channel terminal board for analog modules.

Q: Can the AEA4D-06 support redundant module configurations?
A: Yes. The specified configuration supports both single and dual-redundant modules.

Q: Does the AEA4D-06 itself define the analog signal range?
A: The supplied information does not specify an analog range. The applicable signal characteristics should be confirmed from the connected Yokogawa module documentation.

Field Installation Guidelines

• Mount the terminal board in the designated system location and verify mechanical alignment before wiring.
• Confirm the installed suffix against the required explosion-protection and ISA Standard G3 configuration.
• Identify all 16 channels before connecting field wiring.
• Keep analog signal cables separated from AC power, motor, and high-current switching conductors.
• Apply the specified cable shield and grounding method defined by the system installation design.
• Check terminal identification and polarity against the associated Yokogawa module documentation.
• For dual-redundant configurations, verify that each wiring path matches the approved system architecture before energization.
• Do not apply an assumed signal range, isolation rating, or environmental limit when the associated module documentation does not specify it.
