HIMA HIJunctionBox on-site distributed junction box

​Product basic information

Positioning and attribution: The core component of the HIMA intelligent safety platform on the field side, used for distributed safety signal acquisition and transmission, directly connecting field devices with HIMax/HIMatrix safety controllers (SIS), replacing the traditional architecture of “field devices → marshalling cabinets → SIS”.

Core application scenario: Industrial site safety signal integration, especially suitable for Zone 2 explosion-proof environments and harsh working conditions (such as high dust and humid environments).

Communication and integration characteristics

Communication mode: support two mainstream communication media, adapt to different transmission distance requirements:

Fiber optic: Single mode fiber optic, suitable for long-distance signal transmission;

Copper cable: CAT 6 standard, supports 1000 BaseT Ethernet, suitable for short distance high-speed communication.

Integration advantages:

Direct connection to SIS: No need for intermediate marshalling cabinets, simplifying signal transmission links;

Pre configuration testing: Complete configuration and testing before leaving the factory to shorten on-site debugging time;

Flexible adaptation: Supports redundant or single system architecture for HIMax/HIMatrix controllers, and can combine modules as needed.

Core advantages

Cost optimization: Reduce the procurement and installation costs of marshalling cabinets, decrease the amount of cables used from the site to SIS, and minimize the space occupation in the control center;

Efficiency improvement: Standardized design shortens FAT (Factory Acceptance Testing) cycle, simplifies wiring engineering, and eliminates the need for rewiring for I/O changes;

Strong reliability: IP66 protection+316L stainless steel shell, suitable for harsh industrial environments, Zone 2 explosion-proof certification expands application scenarios;

High flexibility: compatible with multiple security modules, supports custom security policies, and adapts to the needs of industrial sites of different scales.
