MeloAuto-Trusted PLC & DCS Parts Supplier
This Siemens rack provides a sturdy mounting base for S5 series automation components. The Siemens 6ES5135-3KB41 accommodates up to 12 modules in a compact layout. Its rugged construction ensures reliable support for all inserted cards. This rack requires an external power supply for complete system operation. The Siemens 6ES5135-3KB41 offers flexible configuration options for diverse applications. Its design emphasizes space efficiency and straightforward module installation.
Physical Structure and Slot Configuration
This rack measures 482 mm in width and 262 mm in height. Its overall depth reaches 215 mm including the mounting brackets. This unit weighs approximately 3.8 kilograms without power supply modules. The housing features 12 slots arranged in a single horizontal row. Each slot accepts any standard S5 19-inch module format. The Siemens 6ES5135-3KB41 uses a passive backplane for signal distribution. This backplane supports both 8-bit and 16-bit module interfaces.
Backplane Specifications and Electrical Characteristics
The backplane provides a 5 V DC supply rail to all connected modules. This rail delivers a maximum current of 10 A for power distribution. A separate 24 V DC rail offers up to 2 A for relay outputs. The backplane incorporates 12 address lines for module selection. Eight data lines handle bidirectional information transfer between modules. The Siemens 6ES5135-3KB41 includes built-in termination resistors for signal integrity. Two interrupt lines enable priority-based event handling across the rack. The backplane operates with a propagation delay of approximately 2 microseconds.
Connectors and Installation Features
The rack features a 48-pin female connector for each module slot. This connector provides both signal and power contacts for module interfacing. Two additional connectors supply external 24 V DC power to the backplane. The Siemens 6ES5135-3KB41 includes an energy storage capacitor of 1000 µF. This capacitor compensates for brief power interruptions during operation. A ground terminal provides proper earthing for safety and noise reduction. The rack’s mounting brackets support both 19-inch cabinet and panel installations.

Installation and System Integration
Mount this rack in a standard 19-inch cabinet using the supplied brackets. Position the rack horizontally to ensure proper airflow across all modules. Insert modules from left to right, starting with the CPU in slot one. Connect the external 24 V DC source to the designated terminal strip. The Siemens 6ES5135-3KB41 operates between 0°C and 60°C ambient temperatures. Ensure adequate clearance behind the rack for cable management and routing. Use shielded cables for external connections to reduce noise interference. Ground the rack properly to protect against electrostatic discharge. Regular inspection of the backplane contacts maintains signal reliability.
