Applications
The RECOM RS-2405S is designed for industrial automation systems, PLC backplanes, and distributed I/O nodes powered from 24V plant bus voltage, where a clean isolated 5V logic rail is needed for microcontrollers and sensors. Its 0.5% load regulation maintains a stable supply voltage across load transients, preventing resets in sensitive digital circuits. The 1000V isolation also makes it suitable for fieldbus interface modules and HART-connected instruments where isolation prevents ground potential differences from corrupting signal integrity.

Frequently Asked Questions
What input voltage range does the RS-2405S accept, and does it suit 24V industrial bus systems?
The RS-2405S accepts 18V to 36V input, centered on the standard 24V industrial nominal bus. This wide range accommodates the typical ±15% variation found in 24V plant power systems, including battery-backed UPS rails that may rise above 28V during charging and fall below 22V under heavy load, ensuring uninterrupted 5V output to connected logic.
How well does the RS-2405S maintain output voltage under varying load conditions?
The RS-2405S achieves 0.5% maximum load regulation, meaning the 5V output shifts by no more than 25mV from no-load to full 400mA load. This tight regulation protects ADC reference circuits and precision sensors that require stable supply voltage within ±1% for accurate measurements in industrial data acquisition systems.
In which industrial applications does the 1000V isolation of the RS-2405S provide measurable benefit?
The 1000V isolation barrier of the RS-2405S is critical in motor drive control boards, industrial robots, and fieldbus nodes where the 24V input ground may float at hundreds of volts relative to logic ground due to PWM switching noise or fault conditions. The 1000V barrier prevents this potential from propagating to the 5V side, protecting microcontrollers, CAN transceivers, and RS-485 communication ICs from damage or lock-up.
