The IO terminal block achieves efficient signal and power transmission through modular design, widely used in PLC control cabinets, robotics, and distributed I/O systems.

1. Advantages:

Signal Integration: Integrating multiple input/output (I/O) signals into a single cable to reduce wiring complexity (e.g., consolidating 16 signals into one interface).

Electrical Isolation: Insulators prevent signal interference and ensure transmission stability (e.g., gold-plated contacts reduce resistance).

Quick Maintenance: Supports hot-swapping and tool-free wiring (e.g., spring clamp technology), reducing equipment debugging time.

2. Classification and Key Features

Classified by structure:

Direct insertion type: suitable for high-density scenarios (such as DB37 interface), supporting 32A current load.

Rail mounted type: compatible with DIN standards, convenient for PLC control cabinet integration (such as European style 8-position terminal block).

Blade type: Ultra thin design (12mm thickness), saving 50% installation space. ‌‌

By signal type:

Digital terminal block: divided into PNP/NPN types, supporting 16-32 channels. ‌

Analog terminal block: integrated temperature/voltage detection, used for precision instruments. ‌
