X20SC0806 8DI 6DO Safe Mixed I/O Module
The B&R X20SC0806 is a high-density mixed safety module with eight type A digital inputs, four pulse outputs and six type B2 safe outputs. It consolidates a complete local safety station into one 25 mm X20 slice, reducing the number of separate input and output modules.
Compared with X20SC0402, it doubles the input capacity from four to eight and triples the output count from two to six. The six 0.2 A outputs provide a total nominal current of 1.2 A and use diagnostic pulses shorter than 10 µs.
This model is particularly useful for multi-axis machines or cells that need to monitor many safety devices and control several compatible electronic enable inputs from one distributed node.
Key Features
- Eight type A safe digital inputs
- Four diagnostic pulse outputs
- Six type B2 safe outputs
- 0.2 A per output and 1.2 A total
- OSSD test pulse shorter than 10 µs
- High channel density in a 25 mm module
Typical Applications
- Multi-axis drive enable systems
- Packaging lines with several safety zones
- Robotic or assembly cells
- Conveyors with distributed input and output points
- Replacement of X20SC0806 modules
Safety and Compatibility Note
The X20SC0806 can be used in safety-related applications up to PL e or SIL 3 only when the complete safety function is correctly engineered, configured, commissioned and validated. The achievable safety level depends on the full sensor, logic, communication, wiring and actuator chain. Check the exact hardware revision, firmware, Automation Studio hardware definition and SafeDESIGNER project before replacing an installed module.
FAQ
Q: What is the channel configuration of X20SC0806?
A: It provides eight safe inputs, six safe outputs and four diagnostic pulse outputs.
Q: What is the total output current?
A: The six 0.2 A outputs provide a total nominal current of 1.2 A.
Q: How does it differ from X20SC0402?
A: X20SC0806 has 8DI/6DO, while X20SC0402 has 4DI/2DO.
Q: Are the outputs type A or type B?
A: They are type B2 outputs intended for compatible reference-potential loads.
Q: Which field-wiring accessories are required?
A: Use one X20BM33 or X20BM36 and two X20TB52 safety-keyed terminal blocks.
Q: Can all electronic inputs accept the OSSD pulses?
A: No. Confirm that each connected input tolerates the specified pulse, leakage current and switching arrangement.
