Yokogawa AER4D-00 S1 Terminal Board

The Yokogawa AER4D-00 S1, also cataloged as the AER4D-00 Terminal Board, operates as a dedicated hardware component for Resistance Temperature Detector (RTD) signal termination within Yokogawa CENTUM VP distributed control systems. Configured as a 16-channel interface panel, the board routes RTD temperature telemetry directly to AAR145 input modules via AKB335 signal cables. The physical layout incorporates M4 screw terminals arranged in single or dual redundant module configurations, isolating field sensor wires and transferring digitized temperature data across the FIO node backplane architecture.

Cold Junction Compensation & FOUNDATION Fieldbus Connectivity

The AER4D-00 S1 maintains stable signal conversion thresholds for 16 discrete RTD channels by preserving constant lead resistance balances across its terminal array. High isolation boundaries (100 Mohm at 500 V DC) prevent field potential differences from degrading low-voltage millivolt signals, ensuring accurate temperature processing when integrating CJC (cold junction compensation) values or passing variables across FOUNDATION Fieldbus / Profibus PA field networks. Dual-redundant wiring layouts support dual AAR145 modules, sustaining continuous temperature tracking and uninterrupted DCS database register updates if a primary signal path fails.

Frequently Asked Questions

Q: How is galvanic isolation maintained between channel groups on the terminal board?

A: The board provides physical isolation designed to withstand 1500 V AC for 1 minute between commons (separated every 8 channels) and 2300 V AC for 1 minute between signal paths and the metal chassis frame.

Q: Can the AER4D-00 S1 board be mounted in standard 19-inch equipment racks?

A: Yes. The board features standard 19-inch rack dimensions (482.6 mm width) and mounts securely using two M5 screw holes on the mounting ears.

Q: What cable assembly is required to connect the terminal board to the AAR145 module?

A: Field connection requires the Yokogawa AKB335 multi-conductor signal cable, which plugs directly into the interface connectors on the terminal board.

Field Installation Guidelines

Terminal Screw Torque: Torque all M4 field wiring screws to 1.2 N m to maintain gas-tight electrical contact and prevent thermal drift caused by loose terminal connections.
Cabinet Frame Grounding: Secure the board frame to the functional earth (FE) rail using designated M5 mounting hardware to ensure proper high-voltage breakdown protection (2300 V AC to case).
Signal Cable Separation: Route low-voltage RTD wiring in dedicated raceways separated by at least 300 mm from 230/400 V AC power lines and variable speed drive outputs to prevent inductive noise interference.
Redundant Cable Routing: When deploying dual-redundant AAR145 module configurations, route primary and secondary AKB335 cables along separate vertical cable ducts to avoid simultaneous mechanical damage.
