Frequently Asked Questions
Can this cable be used with other SDV series modules?
The AKB331-M020 is specifically optimized for the SDV144. Using it with other SDV modules is not recommended, as proper pin-out and SIL safety loop integrity may not be guaranteed.
Is the 20-meter length suitable for outdoor routing?
This cable is intended for indoor installations. For outdoor routing between buildings or exposed areas, additional conduit protection is recommended to preserve lifespan and signal quality.
