The B & R Automation 3PS465.9 is part of the System 2005 Controllers series and features total output power of 60 W with 24 V and 5 V output power ratings of 50 W and 40 W, respectively. It supports a nominal input voltage of 24 VDC, with a minimum of 18 VDC and a maximum of 30 VDC. The controller is designed with a ready relay current of 3 A, equipped with 370 V transient diode relay protection, and includes a backup capacitor of 10000 μF for single-phase operation.
Internal Product Review
The 3PS465.9 is a B & R Automation power supply module for System 2005 controllers, designed for 24 VDC nominal input and 60 W total output power. Output distribution is well balanced with 50 W at 24 V and 40 W at 5 V, which supports dependable controller-side power delivery. A normally open ready relay rated for 3 A adds useful status signaling, making the 3PS465.9 a well-engineered control power solution.

Product Description:
The 3PS465.9 is a power supply module produced by B&R Automation for the System 2005 Controllers series. It converts a 24 VDC field source into stabilized low-voltage rails that power CPU, I/O, and communication cards inside an automation rack. By integrating input filtering, buffering capacitors, and a ready relay, the unit supports uninterrupted controller operation during voltage dips that are common on industrial plant buses.
The module accepts a nominal input of 24 VDC but remains functional between 18 VDC and 30 VDC, so it tolerates brownouts and transient peaks on 24 V distribution lines. Internal input capacitance of 500 µF smooths those disturbances before regulation stages. Two independent outputs are provided: the 24 V rail can deliver up to 50 W for relays, sensors, and actuators, while the logic rail supplies 40 W at 5 V for processors and memory. Combined, the outputs are limited to 60 W to prevent thermal overload. Regulation components are sized for a continuous current requirement of 3.5 A, and external RAM on the controller backplane can be held by an auxiliary 12 V line when the main supply is removed. Relay protection includes a 370 V transient diode that clamps switching spikes generated by inductive loads.
The input side draws 3.5 A at full load and stores energy in two ride-through capacitors: 10000 µF for single-phase sources and 6000 µF for three-phase feeds; these values maintain output for milliseconds if the feeder collapses. A ready relay, specified as normally open, closes when internal voltages reach regulation thresholds and can switch up to 3 A at 30 VDC to inform the controller that power is stable. The same contact is shielded by the transient diode noted earlier, ensuring long mechanical life even when inductive field devices are wired to the signaling circuit.
