Terminal Design and Connection System

This block features 40 screw-type terminals for field signal wiring. Each terminal accepts wires from 0.2 mm² to 2.5 mm² cross-section. The screw connection ensures gas-tight and vibration-resistant terminations. The design supports solid and stranded conductors.

Compatibility and Module Integration

This terminal block fits all ET 200M digital and analog I/O modules. It mounts directly adjacent to the associated I/O module. A connector system links the terminals to the module channels. This integration simplifies cabinet wiring and maintenance procedures.

Wire Preparation and Termination

Users strip wire insulation to 8 mm to 10 mm for termination. Insert the stripped wire into the terminal opening. Tighten the screw to secure the connection. This simple process speeds installation and reduces wiring errors.

Mechanical Construction and Physical Attributes

This block measures 125 mm wide and weighs just 0.18 kg. The compact design saves valuable cabinet space. Removable connectors allow module replacement without rewiring. This serviceability reduces maintenance time significantly.

Electrical Ratings and Performance

Each terminal handles up to 250 V AC and 10 A of current. This rating supports most field devices and sensors. The terminal block maintains low contact resistance. Reliable connections prevent signal losses and heating.

Certifications and Compliance

The 6ES7193-0CB40-0XA0 holds CE, UL, and cULus certifications. These approvals confirm compliance with international safety standards. Each unit undergoes quality inspection before shipment. This commitment ensures reliable performance.
