AKB331-M020 | Yokogawa Signal Cable (50-50 Pins)

Product Overview

The Yokogawa AKB331-M020 functions as a high-density signal transmission link designed for the CENTUM VP and CS 3000 distributed control systems. This 50-to-50 pin cable facilitates the critical connection between I/O modules and terminal boards, ensuring high-speed data flow and signal accuracy. With a length of 20 meters, it provides the necessary reach for complex cabinet-to-cabinet interconnections in large-scale industrial plants. We supply this cable as 100% Brand New and in original factory packaging to guarantee maximum conductivity and system stability.

Engineering Advantages

The AKB331-M020 provides several technical solutions for demanding automation environments:

• High-Density Signal Consolidation: The 50-pin architecture allows a single cable to handle multiple I/O points simultaneously. This reduces the number of individual wires technicians must manage, significantly cleaning up cabinet interiors.

• Superior Electromagnetic Shielding: To combat the noise typical of motor control centers and high-voltage areas, this cable features advanced shielding. It protects sensitive 4-20mA and low-voltage digital signals from external interference.

• Low-Resistance Transmission: Precision-crimped 50-pin connectors minimize contact resistance. This ensures that even at the maximum 20-meter length, signal voltage remains within strict tolerances for precise process control.

• Durable Industrial Jacket: The outer insulation resists oil, heat, and common industrial chemicals. This durability prevents cable degradation in harsh environments, ensuring a service life that matches the longevity of the control system.

FAQs

Can I use the AKB331-M020 for both Analog and Digital signals?

Yes. The AKB331-M020 is a universal signal cable compatible with various Yokogawa I/O modules, including those for analog inputs/outputs and digital logic signals.

Is 20 meters the maximum supported length for this cable series?

While the M020 specifies 20 meters, Yokogawa offers various lengths in the AKB331 series. However, 20 meters often represents the functional limit for many high-speed signal applications before attenuation becomes a factor. Always check your specific I/O module's drive capability.

What is the best way to secure the 50-pin connectors?

The connectors feature integrated retaining screws. Technicians must tighten these to ensure a gas-tight, vibration-proof connection. This prevents intermittent signal loss caused by cabinet vibration or thermal expansion.

Can this cable replace an AKB331-M010?

Yes, functionally they are identical; the only difference is the length. The M020 provides an additional 10 meters of reach. Ensure you manage the excess cable length properly using cable trays to avoid unnecessary loops.
