AED5D-01

The Yokogawa AED5D-01 is a digital terminal board designed for Yokogawa Field Control Unit (FIO) systems. It provides field wiring termination for digital I/O signals and supports both single and dual-redundant configurations. The board accommodates 32 digital signal channels and interfaces with compatible digital I/O modules through dedicated connection cables.

Digital Signal Termination

The AED5D-01 provides the field wiring termination point for digital input and output signals. It connects field-side wiring to the corresponding FIO digital I/O module, organizing signal connections between field devices and the control system.

Its 32-channel arrangement supports high-density digital signal termination. The M4 screw terminals provide individual wiring connection points for field circuits.

I/O Module Compatibility

The AED5D-01 is specified for use with the following Yokogawa digital I/O modules:

• ADV151: 32-channel, 24 V DC isolated digital input module.
• ADV551: 32-channel, 24 V DC isolated digital output module.
• ADV161: 64-channel, 24 V DC isolated digital input module.
• ADV561: 64-channel, 24 V DC isolated digital output module.

For ADV151 and ADV551, the terminal board uses the AKB331 connection cable. ADV161 and ADV561 require two sets of AED5D terminal boards and AKB337 cables to accommodate their 64-channel configurations.

Ordering Configuration

The AED5D terminal board documentation identifies the following configuration options:

• Basic type.
• ISA Standard G3 option.

The -01 ordering designation corresponds to the ISA Standard G3 option in the documented ordering convention. Confirm the complete suffix and hardware revision when selecting a replacement board.

Important: When the AED5D is used in voltage output mode, it does not conform to the Non-Incendive standard. This restriction should be considered when evaluating the applicable installation and hazardous-area requirements.

Frequently Asked Questions

Q: How many digital channels does the AED5D-01 support?

A: The AED5D terminal board provides 32 channels. Applications using the 64-channel ADV161 or ADV561 modules require two AED5D boards.

Q: Can the AED5D-01 be used with both digital input and output modules?

A: Yes. The documented module combinations include the ADV151 digital input module and ADV551 digital output module, as well as the 64-channel ADV161 and ADV561 modules with two terminal boards.

Q: What should be checked before replacing an AED5D-01?

A: Verify the connected I/O module, channel configuration, connection cable and ISA Standard G3 option. Also check the voltage-output operating condition if Non-Incendive requirements apply.
