Key Features
- 5 V nominal input to 24 V isolated output conversion in a compact SIP-4 package enables isolated signal rail generation without a separate transformer design
- Unregulated DC-DC topology with 10% load regulation suits low-power bias supply applications where tight output regulation is not critical
- RECOM RO series SMA/SIP-4 form factor simplifies PCB integration with a 4-pin through-hole footprint compatible with standard 0.1 inch grid layouts
Applications
The RO-0524S is used to generate isolated 24 V bias rails from a 5 V logic supply in industrial sensors, field bus interfaces, and analog signal conditioning circuits requiring galvanic isolation between control and field sides. It suits RS-485 and CAN bus transceiver isolation stages where a 24 V isolated supply powers the field-side circuitry from a 5 V board rail. Its compact SIP-4 through-hole package also makes it a practical choice for isolated gate drive supply generation in low-power motor control and relay driver circuits.

Frequently Asked Questions
What are the input and output voltage specifications of the RO-0524S and what isolation does it provide?
The RO-0524S accepts 4.5 V to 5.5 V input (nominal 5 V) and produces a 24 V isolated output. The DC-DC converter module provides galvanic isolation between input and output, enabling it to generate a 24 V field-side supply from a 5 V logic rail in RS-485, CAN, or industrial sensor interface circuits where ground potential differences exist between the control board and field wiring.
How does the 10% load regulation of the RO-0524S affect its suitability for different circuit types?
The RO-0524S has a maximum load regulation of 10%, meaning the 24 V output can vary by up to 2.4 V between no-load and full-load conditions. This unregulated characteristic makes it unsuitable for precision analog circuits requiring stable reference voltages, but acceptable for gate drive bias supplies, field bus transceiver power rails, and relay coil drivers where ±2 V variation at 24 V has negligible impact on circuit function.
For a PCB using RS-485 isolation, how does the RO-0524S SIP-4 package simplify the board layout?
The RO-0524S in SIP-4 (single inline package, 4 pins) format plugs into a standard 2.54 mm pitch through-hole footprint, requiring only 4 PCB holes in a single row. This eliminates the need for a custom transformer design, keeping the isolated 24 V supply solution within a footprint under 15 mm x 10 mm including bypass capacitors, which is far more compact than a discrete switched-mode isolation supply built from separate transformer and controller components.
When would an engineer select the RO-0524S over a regulated DC-DC converter for an industrial sensor interface?
An engineer selects the unregulated RO-0524S when the downstream circuit has its own LDO or zener post-regulator, or when the load is resistive and well-characterized so that 10% output variation over load is within tolerance. In isolated RS-485 or CAN transceiver bias applications where the transceiver operates over 10 V to 30 V and the load current is stable, the RO-0524S provides adequate performance at lower cost and smaller size than a regulated isolated module.
