Yokogawa AKB331-M005 Signal Cable Assembly

Configured for high-density interconnect routing in CENTUM VP platforms, the Yokogawa AKB331-M005 (AKB331 Signal Cable Assembly) provides direct physical/electrical execution between I/O modules and field terminal boards. It handles discrete and low-level analog signals across cabinet marshalling configurations without introducing transmission noise or contact resistance degradation.

4-20 mA HART Loop and Channel-to-Channel Isolation Characteristics

The AKB331-M005 cable structure incorporates dual-layer shielding to preserve signal integrity for 4-20 mA HART loop protocol passes and digital switching circuits. By mitigating electromagnetic and radio-frequency interference across adjacent conductor pairs, the cable prevents noise coupling into multi-channel analog cards. This transmission path supports full channel-to-channel isolation specs on connected I/O cards, preventing field-side ground loops from transferring backplane faults to controller backplanes.

Frequently Asked Questions

Q: Does the AKB331-M005 connector design allow hot-plugging while the associated I/O module is energized?

A: Physical insertion or removal while energized must follow system safety guidelines. Securing or loosening the dual retention screws during live operation does not interrupt adjacent bus traffic, but individual field loops will experience momentary open-circuit conditions.

Q: What is the specified pin-to-pin wiring orientation for the 50-pin connectors?

A: The AKB331-M005 uses a direct 1-to-1 pin mapping from the 50-pin module interface connector to the corresponding 50-pin terminal board receptacle.

Q: How is the cable drain wire grounded inside the assembly?

A: The overall shield layer connects internally to the metal connector shell, establishing continuous shield grounding to the module frame and terminal board ground plane upon mating.

Field Installation Guidelines

Route the AKB331-M005 cable assembly through designated low-voltage wire ducts inside marshalling cabinets. Maintain a minimum static bend radius equal to 5 times the outer cable diameter to avoid conductor fatigue and shield deformation. Maintain physical separation between this signal cable and high-voltage AC power lines or variable frequency drive outputs to prevent inductive noise pickup. Fully seat both 50-pin connectors into their respective module and terminal board sockets, then hand-tighten both side retention screws to ensure stable electrical contact and strain relief. Bond terminal board ground buses directly to cabinet earth using low-impedance grounding straps.
