Yokogawa AKB331-M015 Signal Cable Assembly
Configured for high-integrity signal routing in Yokogawa ProSafe-RS Safety Instrumented System (SIS) platforms, the Yokogawa AKB331-M015 (AKB331 50-50 Pin Signal Cable) provides direct physical/electrical execution. It serves as a pre-fabricated 50-pin multi-core interconnect assembly designed to connect rack-mounted safety I/O modules, such as the SDV144 digital input module, directly to field termination boards over a 15-meter distance without signal degradation.
Technical Note on Model Classification: Vendor listings occasionally mischaracterize the AKB331-M015 as an "Analog Output Module Assembly." By Yokogawa engineering standards, the AKB331 is strictly a 50-50 Pin System Interconnect Cable (15 meters in length for the -M015 suffix). The connected SDV144 unit operates as a 16-channel digital input module within the ProSafe-RS control architecture.

Channel Isolation and HART Protocol Interfacing
When interfacing with field networks, the multi-conductor assembly preserves galvanic channel-to-channel isolation while supporting 4-20 mA HART loop protocol pass-through without signal attenuation. The internal twisted-pair construction minimizes electromagnetic interference (EMI) and crosstalk between active digital input loop channels. This cable maintains full low-impedance signal integrity across its entire 15-meter run to facilitate reliable diagnostic testing and continuous system verification.
Frequently Asked Questions
Q: Does the AKB331-M015 cable require external power or configuration before deployment?
A: No. The cable functions as a completely passive electrical conduit. Consequently, engineers do not need to apply external power or perform software configuration steps during hardware commissioning.
Q: Can engineers hot-swap the connected I/O module while the cable remains attached to the terminal board?
A: Yes. Technicians can safely disconnect the 50-pin quick-release connector from the front fascia of the module without disturbing the field wiring landed on the remote terminal board.
Field Installation Guidelines
- Cable Tray Routing and Separation: Install the 15-meter cable inside grounded metal raceways or dedicated low-voltage cable trays. Maintain a minimum clearance of 300 mm from 230 VAC/480 VAC power lines to prevent induced noise.
- Bending Radius Compliance: Maintain a minimum structural bend radius equal to at least six times the outer cable diameter during installation. Avoid sharp bends near the connector backshells to prevent internal conductor fatigue.
- Shield Grounding Procedure: Verify that the cable drain wire terminates directly to the cabinet earth ground bar. Connect the shield at a single earthing point to prevent earth loop currents from degrading process signal loops.
