Siemens 3RK1903-0CE00 Brake Control Module

Description

Siemens 3RK1903-0CE00 Brake Control Module

Product Dimensions：

The Siemens 3RK1903-0CE00 is an XB3 Brake Control Module designed for the ET 200S distributed I/O motor starter system. It is used alongside motor starters (such as the DS1-X direct-on-line starter or RS1-X reversing starter) to actuate mechanical motor holding brakes operating on 24 V DC.

Technical Parameters

Product Advantages

• Seamless ET 200S Integration: Fits directly into the modular ET 200S backplane, reducing wiring complexity and cabinet footprint.
• Fast Mechanical Brake Control: Allows rapid actuation of 24 V DC mechanical holding brakes synchronized with the motor switching state.
• Local Control Capability: Equipped with 2 digital inputs (DI) for localized sensors or manual overrides, freeing up main PLC I/O ports.
• High Output Drive: Supports up to 4 A of continuous load current, sufficient for most industrial motor brake coils.

Important Considerations & Precautions

• Legacy Lifecycle Notice: The ET 200S system has been succeeded by the ET 200SP system. Ensure this module is specified for active spare-part maintenance or existing machine retrofits.
• Terminal Module Dependency: The module requires a compatible terminal module (e.g., TM-XB215) for physical mounting and external wiring connection.
• Freewheeling Diode Protection: Ensure the inductive load (brake coil) and wiring adhere to Siemens installation guidelines to prevent back-EMF spikes from affecting system electronics.
• Power Supply Sizing: The 24 V DC auxiliary power supply must be capable of providing adequate current spikes associated with fast brake coil energization.

Product Applications

• Conveyor Systems: Holding belts and rollers safely in place during stop commands or emergency halts.
• Hoists and Elevators: Controlling mechanical safety brakes on small vertical lifting equipment.
• Machine Tools & Packaging Lines: Precision position retention when motors are de-energized.
• General Material Handling: Actuating 24 V DC mechanical brakes tied to standard ET 200S motor starters.
