Product Description

The Yokogawa AKB331-M015 is a high-performance 15-meter signal cable engineered for use with SDV144 (16-channel safety digital input modules) and field terminal boards. It is a critical component of ProSafe-RS Safety Instrumented Systems (SIS), ensuring reliable transmission of safety-critical 24V DC signals from devices such as emergency stop buttons, gas detectors, and process sensors.

Featuring 50-pin MIL-spec connectors on both ends, the AKB331-M015 delivers a secure, vibration-resistant connection essential for SIL-rated applications. Its EMI-shielded construction and durable PVC insulation maintain signal integrity even in electrically noisy industrial environments like offshore platforms, refineries, and chemical plants.

Technical Specifications

Application Scenarios

The AKB331-M015 is ideal for industrial marshaling where SDV144 input modules are installed in I/O cabinets and need to connect to field terminal boards up to 15 meters away. Its length provides flexible wiring layouts in oil and gas facilities, offshore platforms, power plants, and chemical refineries, ensuring safe and reliable communication for safety-critical processes.

Technical FAQ

Can this cable be used with other modules like SDV531 or SDV541?
Yes. The AKB331 series is compatible with multiple Yokogawa safety I/O modules that use the 50-pin MIL connector, including both input and output modules.

What does the M015 suffix mean?
The M015 denotes the cable length in meters. Yokogawa offers the AKB331 series in various lengths (e.g., M001 = 1 m, M005 = 5 m) to suit different cabinet layouts and field distances.
