Key Features
- Unregulated 24 V to 24 V DC-DC module with 21.6 V to 26.4 V input range for industrial 24 V bus systems
- Compact 4-pin SIP package enabling drop-in integration with minimal PCB footprint in space-constrained designs
- REACH-compliant construction with single output for straightforward 24 V rail replication or isolation
Applications
The RO-2424S is suited for industrial automation and process control systems that operate on a 24 V DC bus and require a galvanically isolated or buffered 24 V supply rail for sensors, actuators, or I/O modules. Its unregulated output with up to 10% load regulation makes it appropriate for applications where downstream point-of-load regulators provide final voltage accuracy. The 4-pin SIP form factor simplifies board integration in DIN-rail mounted control modules and industrial communication interfaces.

Frequently Asked Questions
What input voltage range does the RO-2424S accept and what is the nominal input voltage?
The RO-2424S accepts an input voltage from 21.6 V to 26.4 V with a nominal input of 24 V, covering the tolerance band of standard industrial 24 V DC bus systems. This ±10% input range allows the module to operate correctly even when the source bus voltage fluctuates due to load transients or supply variations common in PLC and industrial automation environments.
How does the 10% load regulation of the RO-2424S affect downstream circuit design?
The RO-2424S has a maximum load regulation of 10%, meaning the 24 V output can shift by up to 2.4 V between no-load and full-load conditions. For circuits requiring tight voltage accuracy, designers should follow the RO-2424S with a linear regulator or a switching regulator rated for a 24 V input to achieve regulation better than 1%, ensuring stable supply for analog sensors, 4-20 mA transmitters, or precision instrumentation.
What package does the RO-2424S use and how does it simplify integration into industrial control boards?
The RO-2424S is supplied in a 4-pin SIP (Single Inline Package) with JESD-30 code R-XSMA-P4, allowing direct through-hole PCB mounting without special tooling. The SIP format is compatible with standard 2.54 mm pitch through-hole pads, making it easy to integrate into industrial PCBs alongside relay drivers, opto-isolators, and terminal block connectors commonly used in control panels.
Is the RO-2424S appropriate for use in a 24 V industrial sensor power supply, or is a regulated module recommended instead?
The RO-2424S is appropriate when powering sensors or actuators that tolerate supply variations of up to 10% and do not need tight regulation, such as digital I/O modules or solenoid valve drivers operating from 20 V to 28 V. For precision analog sensors, 4-wire transmitters, or any load requiring output voltage accuracy better than ±2 V at 24 V, a regulated DC-DC module with output voltage tolerance under 2% is the better choice.
