Yokogawa AEA4D-00 S1 Terminal Board

Configured for analog signal connection in CENTUM VP and CENTUM CS 3000 systems, the Yokogawa AEA4D-00 S1 (AEA4D-00 Terminal Board) provides direct physical/electrical execution. The unit links 16 channels of field analog signals, including 4-20 mA current loops, voltage, RTD, and thermocouple transmitters, directly to system analog I/O modules via M4 screw terminals arranged in an 8 points x 2 configuration. It accepts both single and dual-redundant I/O module topologies to execute deterministic signal transfers across CENTUM DCS platforms.

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation

The terminal board routes field wiring directly to system I/O modules while maintaining robust signal separation across all 16 process loops. Internal dielectric paths provide a withstand rating of 500 VAC between field terminal points and logic reference planes to suppress electrical noise and common-mode potential shifts. When mated with compatible CENTUM analog modules (such as AAI143 or AOI143), the physical terminal layout maintains channel-to-channel isolation and preserves digital signaling integrity for 4-20 mA HART loop protocol devices operating across noisy industrial environments.

Frequently Asked Questions

Q: What specific field signal types can be connected to the M4 terminal screws?

A: The M4 screw terminals accept 4-20 mA current signals, DC voltages, RTDs, and thermocouple field leads for direct routing to DCS analog input/output cards.

Q: How does the basic AEA4D-00 variant differ from enhanced models like the AEA4D-05?

A: The AEA4D-00 represents the basic terminal board design without integrated surge absorbers, whereas models such as the AEA4D-05 feature built-in surge protection components.

Q: Can this terminal board support dual-redundant analog I/O module pairs?

A: Yes, internal cabling paths allow the 16 field channels to interface simultaneously with dual-redundant analog I/O module pairs without requiring signal splitting hardware.

Field Installation Guidelines

Mount the terminal board securely onto standard rack structures using M5 mounting screws inserted through the integral side mounting flanges.
Strip field cable insulation back to the required length and crimp M4 ring or spade lugs onto all field conductors.
Fasten field conductors to the M4 screw terminals using a calibrated torque screwdriver set to 1.2 Nm to guarantee low-resistance electrical contact.
Connect all overall and individual cable shield drain wires directly to the dedicated field ground bar to establish an effective single-point ground path.
Plug the dedicated multi-core signal interface cable firmly into the board connector and lock the side latching levers to prevent connector detachment.
Perform a continuity check and measure insulation resistance across terminals using a 500 VDC megohmmeter prior to energizing connected analog loops.
