Introduction to the Siemens 6ES7136-6RA00-0BF0
When a control system demands reliable switching of loads up to 5 A, the 6ES7136-6RA00-0BF0 from Siemens delivers. This fail-safe digital output module is part of the SIMATIC ET 200SP family, engineered for safety-related applications. It provides a single output channel capable of handling both 24 VDC and 24 to 230 VAC loads.
For maintenance engineers, this module simplifies troubleshooting. Its compact design fits standard mounting rails, and its firmware version V1.0.0 ensures consistent performance. The module consumes only 100 mW from the backplane bus, keeping energy costs low.

Key Features and Technical Specifications
The 6ES7136-6RA00-0BF0 offers robust switching capabilities. Below are the essential parameters from the datasheet:
- Product type designation: F-RQ 1x24VDC/24...230VAC/5A
- Hardware product version: 01
- Firmware version: V1.0.0
- Supply voltage type: 24 VDC (coil voltage)
- Permitted range: 20.4 V to 28.8 V DC
- Power consumption from backplane bus: 100 mW
- Power loss, typical: 1 W
- Number of outputs: 1
- Switching capacity with resistive load: max 5 A
- Switching capacity with lamp load: max 25 W
One distinctive feature is the ability to control a digital input directly. This allows the module to act as a bridge between logic and power circuits. Additionally, the module supports I&M data (I&M0 to I&M3), which simplifies asset management in larger installations.
Applications and Use Cases
In industrial automation, the 6ES7136-6RA00-0BF0For example, an emergency stop system can use this module to cut power to a motor starter. Because it handles both AC and DC loads, it adapts to mixed-voltage environments.
Maintenance teams appreciate its fail-safe nature, which reduces the risk of unintended operation. Its single-channel design simplifies wiring and reduces the chance of cross-connection errors.

Installation and Setup
Mounting the 6ES7136-6RA00-0BF0 is straightforward. It snaps onto a standard mounting rail, as indicated by the rail mounting capability. Ensure the backplane bus connector is properly seated to maintain communication with the ET 200SP station.
When wiring, verify that the supply voltage is within the permitted range of 20.4 V to 28.8 V DC. Use appropriate fusing for the output circuit, especially when driving inductive loads. Refer to the Siemens manual for detailed wiring diagrams and terminal assignments.
Maintenance and Reliability
For long-term reliability, inspect the module periodically. Check for loose connections, signs of overheating, or contamination on the enclosure. Because the module has no moving parts, wear is minimal. However, verify that the firmware remains up to date, as Siemens may release improvements.
The fail-safe design means that in the event of an internal fault, the output goes to a safe state. This reduces downtime and protects downstream equipment. Always follow the manufacturer's safety manual when performing any maintenance.
Compatibility and Integration
The 6ES7136-6RA00-0BF0 integrates with STEP 7 TIA Portal V13 or higher, and STEP 7 V5.5 SP4 or higher. The module supports I&M data, which helps in identifying the module in a plant network.
It is designed for the SIMATIC ET 200SP distributed I/O system. Therefore, it works with any ET 200SP interface module that supports fail-safe I/O. No special cabling is required beyond standard ET 200SP bus connectors.
Troubleshooting Common Issues
If the output does not switch, first check the supply voltage. Ensure it is between 20.4 V and 28.8 V DC. Next, verify that the load does not exceed 5 A resistive or 25 W lamp load. Overloads can cause the module to trip into a safe state.
Communication errors may occur if the module is not properly seated in the backplane. Re-seat the module and check the station configuration in TIA Portal. If the module still fails, consult the Siemens diagnostics buffer for specific error codes.
