RDL -24 Vdc Switching Power Supply Distributor

Ideal Use Cases

The RDL TX-PD8X is designed for systems that need a single 24 Vdc source distributed to multiple connected loads. It provides up to eight power distribution points while keeping total load current within 2 A. That configuration fits installations where several compatible devices share a current-limited switching supply and centralized activation is required. Outputs may be activated locally with an external switch, through an open-collector closure to ground, or directly from RDL remote controls. The distributor itself requires 24 Vdc at 25 mA, in addition to the power drawn by connected loads.

Why Choose This Model

This model brings together distribution, activation control, status indication, and input protection in one unit. Its soft-start function operates from the switching supply, while the available control methods let an integrator choose the activation approach that matches the surrounding system. A POWER LED provides voltage-presence indication, giving a direct visual check at the unit. Reverse-voltage protection is also included. For projects based on RDL control hardware, direct compatibility with RDL remote controls is a specific advantage; external-switch and open-collector activation preserve options for other control arrangements.

Installation and Integration

The TX-PD8X is intended for use with a current-limited switching supply at 24 Vdc. The specified input/output rating is 24 Vdc at 2 A, and the combined load across all eight outputs must not exceed 2 A. The listed recommended supplies are the PS-24V3 for international use and PS-24V3A for the USA. During integration, account for the distributor’s 25 mA requirement as well as every connected load. The unit measures 3.17 inches wide by 1.76 inches high by 2.06 inches deep, or 8.05 by 4.47 by 5.23 cm, and is specified for ambient operation from 0 degrees C to 55 degrees C.

Performance Highlights

At its core, the TX-PD8X provides eight outputs for shared 24 Vdc distribution. The 2 A figure applies to the total load current, not to each output independently. This limit is central when planning the connected equipment. Soft-start operation is available from the switching supply, and output activation can be initiated by an external switch, an open-collector closure to ground, or an RDL remote control. The POWER LED confirms voltage presence, while reverse-voltage protection addresses reversed supply voltage at the unit. These capabilities define its performance more precisely than output count alone.

What Makes It Different

What distinguishes this model is the combination of eight distribution points and three documented activation paths. A basic distribution requirement can therefore be paired with a physical switch, an open-collector control signal, or direct RDL remote control without changing the stated 24 Vdc distribution role. The unit also adds a soft-start function, voltage-presence indication, and reverse-voltage protection within dimensions of 3.17 by 1.76 by 2.06 inches. Supporting resources listed for the TX-PD8X include a PDF specification sheet, an engineering functional-block CAD file, and front and rear panel diagrams in American DXF format.

Final Assessment

The TX-PD8X is a focused solution for distributing a current-limited 24 Vdc switching supply across as many as eight points. Its best fit is determined by three concrete requirements: all connected loads operate from 24 Vdc, their combined current stays within 2 A, and one of the documented activation methods suits the control design. The 25 mA unit requirement must be added to connected-load demand. For installations that meet those limits, the model offers clearly defined power distribution, soft-start behavior, selectable activation, visible power status, and reverse-voltage protection within its stated physical dimensions.
