Product Description:
The X20DO4322 is a digital output module from B & R Automation that fits into the X20 Fieldbus Input Output Modules series. Installed on a remote I/O slice, it links a PLC bus backplane to field devices that require 24 VDC switching, so actuators or signal lamps can be energized without auxiliary relays. Its role in an automated cell is to translate control bits on the system bus into discrete voltage levels while maintaining a slim footprint that simplifies cabinet layout. This arrangement is useful where machine sections need distributed switching close to valves, indicators, or interface relays instead of routing every load back to a central cabinet terminal strip.
This unit provides a channel count of 4, giving four individually addressable outputs. Each channel delivers a sourcing voltage of 24 VDC, so positive potential is supplied to the load when the control bit is true. The configured output type is therefore Source, matching sensors and actuators that reference the common return on the module. Per channel load capacity is limited to 0.5 A, which accommodates most indicator lamps, solenoids, and small contactor coils. The electronics are housed in an enclosure carrying a protection rating of IP20, restricting installation to clean, dry panels. For transient events on industrial power rails, its insulation follows overvoltage category II, indicating suitability for circuits directly connected to the low-voltage distribution system without severe surge exposure. Separate channel addressing also lets the controller switch independent loads without interposing extra output hardware.
Total bus power drawn for backplane communication is 0.16 W, while the internal I/O circuitry adds a further 0.49 W; these low figures minimize thermal load inside dense racks. Mechanical ruggedness is demonstrated by a shock resistance of 15 g and a vibration tolerance of 1 g, allowing dependable service on equipment frames subject to normal industrial motion. Outputs are protected against reverse wiring and short circuits, and the module’s compact form factor lets multiple X20 slices be stacked side by side for scalable digital expansion. The protection built into the output stage helps reduce disruption from wiring mistakes or temporary load faults during normal machine operation.
