Overview

The WEIDMULLER 9662-110 (7760050029) is a passive interface terminal board that simplifies connections between high-density PLC or control system I/O connectors and individual field wires. It converts multi-pole cable inputs into easily accessible screw-clamp terminals, reducing wiring complexity, minimizing errors, and improving maintainability. Its passive design ensures high reliability, as there are no active electronics that could fail.

Technical Data

Typical Applications

• Automated Assembly Lines: Streamlines wiring from remote PLC racks to sensors, actuators, and interlocks.

• Complex Marshalling Cabinets: Organizes multi-core cables into clearly labeled screw terminals.

• OEM Machine Integration: Standardizes panel designs for repeatable and fast machine setup.

• Testing & Debugging: Provides secure access points for measurement tools without disturbing permanent wiring.

FAQ

Q1: Why use a passive terminal board instead of wiring directly to PLC I/O cards?
A1: It protects the PLC I/O card from mechanical stress and frequent wiring changes, offering larger, more durable terminals for easier and safer connections.

Q2: Does the 9662-110 include built-in fusing?
A2: No, it is purely passive. Any fusing must be provided externally using fuse terminal blocks.

Q3: What environments are screw-clamp terminals best suited for?
A3: They are ideal for industrial environments with vibration or temperature changes due to their high mechanical clamping force, ensuring secure and reliable wire termination.
