6. Frequently Asked Questions (FAQ)

What is the HardFiber Brick? It is a rugged process interface unit that converts analog field signals to digital data sent over optical fiber, reducing traditional copper cabling in substations.

Why use the BRICK-4-HI-S-CV50 configuration? The CV50 option supports specific current and voltage inputs, while HI denotes the high-range power supply suitable for typical substation environments.

Is this Brick suitable for outdoor use? The HardFiber Bricks are designed for mounting in marshalling cabinets and switchyard kiosks with appropriate environmental protection.

How does it communicate? Via dedicated optical fiber links to the central Multilin relay or controller in the control house.

Is the HardFiber system still supported? Yes. It remains a viable solution for new and existing digital substation projects.

What testing is done on these units? Power supply verification, input channel testing, fiber communication checks, and environmental stress where applicable. Test reports available on request.

What should I verify before installation? Confirm fiber routing, power supply specifications, and input scaling match the system design. Follow all HardFiber installation guidelines for fiber handling and grounding. Document existing connections if replacing a unit.
