Product Description:

The X20SO6300 is a safety digital output module produced by B&R Automation for the X20 Fieldbus Input Output Modules series. Installed on the system bus, the unit provides solid-state switching signals to actuators in industrial automation cells so a safety controller can disconnect power when faults are detected. By combining six separately controlled outputs in a compact slice, it helps add fail-safe functionality without increasing the size of the I/O rack. This arrangement is suited to machines that need monitored shutdown paths for contactors, valves, and similar field devices.

The module operates from a field supply of 24 VDC. It has 6 channels, and each channel is rated for a continuous source current of 0.2 A, while the backplane limits the total current to 1.2 A. The output stages use FET technology with two positive-switching paths in the type B1 variant, which supports rapid energy dissipation up to 45 VDC during braking and accepts capacitive loads up to 100 nF. A maximum I/O cycle time of 1 ms works with a switching ceiling of 100 Hz, so relays and position valves receive timely updates. The module also applies a 10 microsecond test pulse during each cycle to support channel diagnostics.

Galvanic isolation is rated at up to 500 Veff between the field side and the internal logic. The internal circuitry can withstand a fault surge of 10 A without permanent damage, and the mean time to dangerous failure is listed as 2500 years. The safety data also states a probability of dangerous failure on demand below 2 × 10⁻⁵ and a PFH of less than 1 × 10⁻¹⁰ per hour. To maintain these reliability values, the specified proof-test interval is 20 years. These safety figures support applications that require dependable shutdown behavior and consistent diagnostic coverage during fault conditions.
