Core Technical Specifications

This bus terminal provides secure and organized signal distribution for your SIMATIC S5 system. We engineered the 6ES5777-0BC01 to simplify field wiring and maintain signal integrity.

Organized Signal Distribution

The 6ES5777-0BC01 offers 20 screw terminals arranged in two convenient rows for neat cabling. These terminals accept wire gauges from 0.5 mm² to 2.5 mm², covering most field wiring requirements. The module connects directly to the backplane through a reliable 5-pin header. This simple design facilitates quick and accurate wiring of field devices to the control system.

Secure and Reliable Connections

This bus terminal features robust screw-type connections that resist vibration and thermal cycling. Each terminal provides a gas-tight connection, preventing signal degradation over time. The module includes an integrated shield connection for grounding cable screens, reducing electromagnetic interference. Consequently, you can maintain clean, noise-free signals for critical measurement and control circuits.

Compact Design for Cabinet Efficiency

The 6ES5777-0BC01 occupies minimal space with its compact 130 mm x 110 mm footprint. The low profile and 0.15 kg weight simplify mounting on standard DIN rails. Removable labeling strips allow clear identification of each terminal point for easier troubleshooting. This thoughtful design accelerates installation, commissioning, and subsequent maintenance activities.

Versatile Application Support

This bus terminal serves as a central connection point for discrete I/O, power supplies, and communication cables. Its 20-terminal capacity handles multiple field devices simultaneously, reducing the need for additional junction boxes. The module operates across a 0 °C to 60 °C temperature range, suiting most industrial environments. The gray housing ensures visual consistency with other SIMATIC S5 components in your rack.

Simplified Maintenance and Upgrades

You can access all wiring points easily after installation, simplifying inspection and replacement. The terminal screws accept standard screwdrivers, allowing quick adjustments without special tools. The 6ES5777-0BC01 also supports hot swapping in many configurations, minimizing downtime during maintenance. This user-friendly design makes the module a practical choice for both new installations and retrofit projects.
