BV7046-4 is a 4-meter CPU redundancy / bus terminal connection cable for the German HIMA H41q/H51q safety system. It is used for high-speed data synchronization and communication between the CPU redundancy units of the H41q/H51q system and the H7506 bus terminal, ensuring the stable operation of the SIL3 level safety redundant system.

Basic Information

Model: BV7046-4 (Length 4m)

Brand/Series: HIMA / H41q, H51q

Function: CPU redundant unit ↔ H7506 bus terminal (redundant synchronization, high-speed data interaction)

Usage: Safety redundant system connection, CPU hot standby synchronization, H7506 bus terminal communication

Specification parameters

Cable type: Special high-speed shielded twisted pair (suitable for differential signals)

Connector: Pre-installed HIMA dedicated rectangular connectors at both ends (male / female, anti-misinsertion)

Standard length: 4 m (BV7046-4), also available in 2 m specification (BV7046-2)

Communication protocol: High-speed differential (RS-485 compatible), redundant synchronous dedicated

Temperature range: -40°C ~ +105°C (industrial grade)

Certifications: CE, RoHS, meets SIL3 safety system anti-interference requirements

Key features

Redundant dedicated: Specifically designed for HIMA H41q/H51q redundant architecture, ensuring real-time synchronization and seamless switching of primary and backup CPUs, in line with SIL3 safety level.

4-meter long range compatibility: 4-meter length compatible for cross-cabinet, long-distance redundant system wiring, overcoming the short-distance limitation of 2 meters (BV7046-2).

High-speed stable transmission: Differential transmission + shielded structure, zero packet loss in data transmission in strong interference industrial environments, ensuring real-time interaction of safety signals.

Plug-and-play: Pre-installed dedicated connectors at both ends, no on-site crimping required, quick deployment within the cabinet, reducing construction risks.

Typical applications

Redundant CPU connection: The H41q/H51q primary/backup CPU units are connected to the H7506 bus terminal through BV7046-4 to achieve redundant synchronization and fault switching.

Cross-cabinet safety system wiring: 4-meter length compatible for adjacent cabinets, cross-cabinet redundant architecture, neat wiring, strong anti-interference.

SIL3 level safety system: Used for emergency stop systems (ESD), burner management systems (BMS), etc., in high-safety-level scenarios.
