Siemens 6ES5735-8BB00 Industrial Automation Component

The Siemens 6ES5735-8BB00 Industrial Automation Component connects field devices to SIMATIC S5 systems. This component provides screw-type termination for digital I/O signals. You will find it in control cabinets across many manufacturing industries. It mounts directly on standard DIN rail for easy installation. Therefore, this unit simplifies field wiring and reduces installation time.

The Siemens 6ES5735-8BB00 Industrial Automation Component measures 85 mm in height and 45 mm in width. Its depth reaches 30 mm for DIN rail mounting. The unit weighs approximately 0.12 kilograms. It contains no active electronic components at all. Twelve screw terminals accept field wiring from sensors and actuators. Additionally, you get a 12-pin ribbon cable for module connection.

Key Technical Specifications

Internal Architecture and Energy Storage

The Siemens 6ES5735-8BB00 Industrial Automation Component stores absolutely no electrical energy internally. It contains no capacitors, batteries, or semiconductor devices. Twelve screw terminals connect directly to a 12-pin ribbon cable. Each terminal has a direct copper trace path to its corresponding cable wire. A high-temperature plastic housing protects all connections from dust. Each terminal uses a rising cage clamp for secure wire retention. This clamp design provides vibration resistance for industrial environments. The included ribbon cable measures 300 mm in length. A polarizing connector prevents incorrect attachment to the I/O module.

Connection Interfaces and Wiring Details

You will find 12 screw terminals in a single row on the component. Each terminal accepts 24 to 14 AWG copper wire. Use a 3mm flathead screwdriver to loosen and tighten each screw. Strip 7 mm of insulation from each wire before insertion. Then, insert the bare copper into the terminal opening. Tighten the screw to 0.5 Nm of torque maximum. The Siemens 6ES5735-8BB00 Industrial Automation Component includes a 12-pin ribbon cable with female connector. Connect this cable to the front of a compatible S5 I/O module. Align the connector keyway carefully before pressing it in. The component requires no external power supply at all. It simply routes signals between field devices and the I/O module.

Installation and Mounting Steps

You mount this component onto standard 35 mm DIN rail. First, hook the top clip onto the rail edge securely. Then, press the bottom toward the rail until it snaps into place. Slide the component along the rail for easy panel layout. Connect all field wiring before attaching the ribbon cable. Label each terminal with its corresponding signal name clearly. The Siemens 6ES5735-8BB00 Industrial Automation Component requires no external power supply. Connect the ribbon cable to the front of your S5 I/O module. For high-vibration areas, add end stops on both rail ends. Test each connection with a continuity tester before power-up. Secure the ribbon cable away from sharp edges or moving parts.
