Yokogawa AKB336 Signal Cable

TheYokogawa AKB336-M010also cataloged astheAKB336 Signal Cable, operates as a dedicated hardware component for point-to-point 20-pin signal interconnection within Yokogawa CENTUM VP, CENTUM CS 3000, and ProSafe-RS Field I/O architectures. The assembly provides fixed electrical continuity between FIO modules and termination hardware via shielded multi-core routing.

Suffix Breakdown & Model Matrix

• AKB336: Base series designation for 20-pin to 20-pin signal cable assembly
• -M010: Factory-defined cable length variant, 10 m nominal length

No further functional segmentation is defined by manufacturer beyond length-coded ordering.

Process Control Signal Integrity Characteristics

The AKB336 series is implemented within distributed control environments where deterministic signal routing is required between Field Control Stations and I/O termination assemblies. Within Yokogawa process automation architectures (Yokogawa Electric Corporation), channel-to-channel separation is maintained through shielded conductor geometry to reduce cross-interference in mixed analog/digital signal backplanes operating in 4-20 mA and discrete logic domains. The cable construction supports stable signal propagation under cabinet-level electromagnetic noise conditions typical of densely populated DCS racks.

Frequently Asked Questions

Q: Does the AKB336-M010 support hot-swap during system operation?
A: No. The cable is a passive interconnect assembly and requires de-energized handling before disconnection to avoid signal disruption on connected I/O modules.

Q: Is there electrical isolation built into the cable structure?
A: Electrical isolation is not active. Isolation is dependent on connected system hardware; the cable provides shielding only.

Q: Can the cable be used outside Yokogawa FIO architectures?
A: No. Pin mapping and connector geometry are specific to Yokogawa 20-pin FIO interfaces.

Field Installation Guidelines

• Ensure system power is fully isolated before installation or removal
• Maintain continuous shield termination at designated grounding points on cabinet structure
• Avoid routing parallel to high-voltage or inverter output cabling
• Do not exceed minimum bend radius defined by cabinet wiring standards
• Verify full 20-pin seating alignment before securing connector locks
