Product Overview

The Yokogawa AKB337-M020 is a high-integrity signal interface cable (often referred to as a KS Cable) specifically designed for CENTUM VP and ProSafe-RS Distributed Control Systems. This 20-meter cable facilitates the direct, high-density connection between Field I/O (FIO) modules and their corresponding terminal boards or marshalling panels. By utilizing the AKB337-M020, engineers eliminate the need for thousands of individual point-to-point wires, significantly reducing the risk of wiring errors and accelerating system commissioning in oil & gas, chemical, and power facilities.

(Note: While some references mistakenly categorize the AKB337 as a power module, it is technically a high-performance signal cable for DCS interface.)

Condition: 100% Brand New, New Old Stock (NOS), Original Japan.

Part Number Breakdown: AKB337 Series

Yokogawa uses a structured suffix system to define cable interface types and lengths.

AKB337: Signal Interface Cable (KS Cable) for FIO modules.
-M: Metric measurement standard.
020: Specifies a total length of 20 Meters.
-NL: Standard non-explosion protected, standard sheath variant.

Engineering Advantages

Elimination of Wiring Errors: The AKB337-M020 uses pre-terminated, keyed connectors. This ensures that every I/O point on the module maps perfectly to the corresponding terminal on the board, removing the possibility of cross-wiring that often plagues manual terminations.
Dramatic Installation Speed: Connecting 32 channels of I/O via a single AKB337-M020 cable takes seconds compared to hours of stripping, crimping, and labeling individual wires. This speed is vital for meeting tight deadlines during plant turnarounds or new construction.
Superior Noise Immunity: The cable features integrated shielding and twisted-pair architecture. This design effectively rejects electromagnetic interference (EMI) and radio-frequency interference (RFI), maintaining signal purity for sensitive 4-20 mA analog loops over the full 20-meter distance.
Space Optimization in Racks: The multi-core design significantly reduces the bulk of cable bundles within the control cabinet. This improves airflow and allows for more organized, manageable cable management in high-density FIO nests.

FAQs

Q: Can I cut the AKB337-M020 to a shorter length?

A: We do not recommend cutting the cable. The connectors are factory-molded and tested for signal integrity and impedance. Shortening the cable manually risks introducing noise and voids the technical performance specifications. If you require a shorter run, please select the M005 (5m) or M010 (10m) variants.

Q: Does this cable support both analog and digital signals?

A: Yes. The AKB337-M020 carries standard 24V DC digital signals and 4-20 mA analog signals. However, ensure that the I/O module and terminal board pins match the cable's internal pinout configuration.

Q: What is the benefit of the "NOS" (New Old Stock) status?

A: NOS indicates the product is 100% brand new and unused, typically held as a spare part. It provides a cost-effective way to acquire original Yokogawa hardware that maintains the same performance standards as current production runs.

Q: Is the 20-meter length too long for 4-20 mA signals?

A: No. Because the AKB337-M020 uses high-quality tinned copper and appropriate gauge conductors, signal attenuation is negligible at 20 meters, provided the loop resistance stays within the 750 Ω limit of the output module.
