Product Description:

The 0GH-D0480 is a digital output module produced by B&R Automation for the 0GH PLC Modules series. Mounted in a control rack, this component provides sixteen sourcing transistor outputs that let the controller switch solenoids, relays, or indicator lamps directly from its logic program. By converting low-level CPU signals into field-side power, the unit serves as a link between the programmable controller and the machine devices it commands in distributed I/O stations used throughout industrial automation systems.

Each channel is designed for a nominal supply of 24 VDC and may switch loads up to 48 VDC. The per-channel output limit is 2 A, while each eight-output group is limited to 12 A so the power distribution traces are not overstressed. A maximum switching frequency of 500 Hz allows pulse-width modulation of resistive or inductive loads, and a typical turn-on delay of 4 µs keeps output transitions closely aligned with controller scan times. The module uses a sourcing output circuit, which means the transistor drives the high side of the load. Braking voltage is clamped to 50 V to protect the semiconductors, and channel residual voltage stays below 0.3 V during conduction to minimize heat.

The module can tolerate a brief short-circuit surge of 90 A, after which a fast electronic cutoff works with the 24 A overall module current limit to help prevent trace damage. When a channel is disabled, it leaks only 0.1 mA, so most field devices remain fully de-energized. The typical turn-off delay is 100 µs, which matches inductive discharge times and supports deterministic stop behavior at high duty cycles. With all logic and driver circuitry active, the board draws just 2.5 W, leaving ample power budget for dense I/O clusters. Sixteen outputs are arranged as two groups of eight, which simplifies field wiring and load organization.
