Design and Construction

The D1063S comes in a rugged DIN‑rail mountable housing with polarized screw terminals for secure connections. Internally, the isolator uses precision circuitry to perform three‑port galvanic isolation — separating input, output, and power supply paths to prevent electrical interference and ensure measurement integrity. DIP switches allow flexible configuration of reference voltage sources (internal or external).

Core Features & Advantages

• Intrinsic Safety Compliance: Designed for use with load cells in hazardous environments (can be installed in safe zones adjacent to Zone 0 hazardous areas) without requiring external Zener barriers.

• High Parallel Capacity: Supports multiple load cells in parallel, making it suitable for systems with several force sensors.

• Fault Monitoring: Built‑in LED indicates wiring faults or open field circuits, simplifying troubleshooting.

• Noise Immunity: Galvanic isolation improves signal clarity, minimizing ground loop and EMI problems.

Typical Applications

This isolating repeater is widely used in:

• Industrial weighing systems and scales

• Load monitoring in hazardous areas (oil & gas, chemical plants)

• Conveyor tension measurement and process control

• Offshore and marine load measurement (with appropriate certifications)

• Any application requiring safe, isolated load cell signal interfacing

Installation & Best Practices

The unit is installed on a standard DIN rail inside control or distribution cabinets. Ensure proper grounding and shielding of sensor cables to maintain signal integrity. DIP switch settings should be configured according to system reference voltage and load cell type. Periodic inspection of wiring and LED fault indicators helps maintain operational reliability.
