Yokogawa AKB336-M002 Signal Cable

Configured for signal transmission between I/O modules and terminal boards in CENTUM VP and CENTUM CS 3000 systems, the Yokogawa AKB336-M002 (AKB336 Signal Cable) provides direct electrical interconnection through a 50-pin to 50-pin cable assembly. The -M002 suffix designates a factory-defined cable length of 2 m for module-to-terminal board wiring applications.

Channel-to-Channel Signal Integrity Characteristics

Within Yokogawa DCS architectures, the AKB336-M002 functions as a passive signal transport medium between field control station I/O hardware and terminal interfaces. The cable incorporates overall shielding to reduce external electromagnetic coupling and to maintain signal separation across densely packed conductors. Shield continuity and grounding practices should follow the applicable CENTUM system installation documentation to minimize induced noise on low-level process signals, including 4-20 mA loops and discrete I/O circuits.

Frequently Asked Questions

Q: Does the AKB336-M002 require external power?
A: No. The cable is a passive interconnection component and contains no active electronic circuitry.

Q: Can the cable be shortened or field-modified while maintaining original specifications?
A: The supplied data identifies the cable as a predefined factory-length assembly. Any field modification may alter shielding continuity, conductor characteristics, and connector integrity.

Q: What installation factor most directly affects signal performance?
A: Proper shield termination, adherence to minimum bending radius requirements, and separation from high-power wiring are primary installation considerations for maintaining signal quality.

Field Installation Guidelines

1. Verify connector orientation before insertion into I/O modules and terminal boards.
2. Maintain a minimum bending radius of 80 mm throughout the cable route.
3. Avoid parallel routing with high-current motor, drive, or power distribution cables where possible.
4. Protect the cable sheath from mechanical abrasion and excessive tensile loading.
5. Follow plant grounding practices for shield termination as specified by the associated Yokogawa system documentation.
6. Confirm connector locking mechanisms are fully engaged after installation.
7. Inspect cable shielding and connector housings for damage before commissioning.
