The CYDLGK4 is a double-level disconnect terminal block with knife disconnection and grounding connection, specially designed for industrial control panels, PLC systems, instrumentation circuits, process automation applications, and machine wiring systems. This advanced terminal block combines feed-through connection, test disconnect functionality, and grounding continuity in one compact DIN rail-mounted unit, making it highly useful in industrial electrical systems where safe circuit isolation and troubleshooting are essential.
In modern industrial automation and instrumentation systems, engineers often need to disconnect signal or control circuits temporarily for testing, maintenance, fault finding, or calibration. The CYDLGK4 solves this requirement by integrating a knife disconnect mechanism, which allows the circuit to be safely opened without removing wires from the terminal block. This makes maintenance faster, safer, and more efficient while reducing wiring disturbance.
The double-level design of the CYDLGK4 allows two separate wiring levels in a single compact terminal body. This helps save DIN rail space and improves wiring organization in high-density control panels. The upper level is typically used for disconnect and testing functions, while the lower level supports feed-through wiring continuity. In addition, the integrated grounding (earth) connection provides safe earthing continuity, making the terminal suitable for instrumentation and control applications requiring protective grounding.
One of the key advantages of the CYDLGK4 is its knife disconnection feature. This mechanism allows operators to isolate circuits during maintenance, signal testing, current measurement, or system troubleshooting without disconnecting the conductor physically. This improves technician safety and reduces downtime in industrial systems.
The ground connection integrated into the terminal block helps maintain protective earth continuity for safe electrical operation. In industrial automation systems, grounding is essential for equipment protection, signal stability, and operator safety. By combining disconnect and grounding functionality in one terminal block, the CYDLGK4 reduces component count and simplifies panel design.
Manufactured using high-grade Polyamide insulating material and precision conductive metal parts, the CYDLGK4 offers excellent electrical insulation, heat resistance, corrosion resistance, and long-term mechanical durability. The screw clamp termination system provides secure conductor retention and stable electrical contact even in vibration-prone industrial environments.
The terminal block supports 4 sq.mm conductor capacity, making it suitable for instrumentation circuits, control wiring, low-voltage signal systems, PLC I/O wiring, and industrial machine electrical applications. Its DIN rail mounting design allows quick installation in control cabinets and electrical enclosures.
