Product Description
The AKB331-M020 (AKB331) is a specialized system interface cable for Yokogawa’s ProSafe-RS Safety Instrumented System (SIS). This 20-meter assembly provides a reliable interconnection between the SDV541 digital output module and its associated terminal board. Designed for safety-critical applications, the AKB331 ensures accurate transmission of control signals to final elements such as solenoids and emergency shutdown valves.
With high-density connectors and advanced shielding, the cable mitigates electromagnetic interference (EMI) and radio-frequency interference (RFI), preventing false trips or signal degradation and maintaining safety loop integrity across extended distances.

Frequently Asked Questions
Why is the AKB331 recommended specifically for the SDV541?
The cable is pinned to match the internal architecture of the SDV541. Using a non-compatible cable can cause incorrect signal routing, which is critical in safety loops where each output must correspond precisely to its safety function.
Does this cable support redundant module configurations?
Yes. In a redundant ProSafe-RS setup, two AKB331-M020 cables are typically used—one for each SDV541 module—to connect to a common redundant terminal board, ensuring continuous safety function even if one cable or module fails.
