HIQUEL Diode Boxes

HIQUEL Diode Boxes are compact control modules designed to provide reliable diode isolation in DC control, signalling, and monitoring circuits. They allow multiple control signals to be combined or separated safely without electrical feedback, ensuring dependable logic control in automation systems.

🔧 Technical Highlights:

• Function: Provides diode isolation for DC inputs or outputs to prevent signal backfeed and interference.
• Input Voltage: Typically 24 V DC (models available for other DC voltages on request).
• Configuration: Multiple diode channels in a single compact module for efficient wiring.
• Connection: Screw terminals or pluggable connectors for quick installation.
• Mounting: DIN rail 35 mm for control panels and enclosures.
• Housing: Industrial-grade plastic enclosure with high insulation and mechanical strength.
• Compliance: CE and RoHS certified for industrial and building automation use.

✅ Benefits:

• Prevents unwanted current flow and backfeed in DC control circuits.
• Ensures reliable logic signal separation and protection.
• Compact DIN rail design saves panel space and simplifies installation.
• Maintenance-free solid-state operation with high durability.
• Compatible with relays, PLCs, and control interface modules.

🚀 Applications:

• PLC and relay interface isolation in automation panels.
• Signal direction control for DC logic and monitoring systems.
• Protection of control circuits in machinery and conveyors.
• Interlocking and signal separation in process control systems.
• Voltage-free isolation in alarm, fault, and status indication circuits.

HIQUEL diode boxes provide simple, robust, and reliable diode isolation for safe operation of DC control circuits in industrial and automation applications.

FAQs

• Q: What is the purpose of a diode box?
  A: A diode box prevents unwanted current feedback between parallel control circuits, allowing multiple control signals to be safely combined or separated.
