Key Features
- 24 V nominal input (21.6–26.4 V range) with optional additional -12 V output for dual-rail analog supply generation
- Unregulated DC-DC conversion in compact SIP-7/5 (R-XSMA-P5) through-hole package for easy PCB integration
- RoHS-compliant, REACH-compliant construction with single-function isolated topology for noise-sensitive signal chains
Applications
The RB-2412D is suited for industrial automation boards, analog signal conditioning circuits, and sensor interfaces that require isolated 24 V to 12 V DC-DC conversion from a standard 24 V bus. The optional -12 V auxiliary output makes it particularly valuable for operational amplifier supplies and split-rail analog front-end designs where both positive and negative bias voltages are needed. Its SIP-7/5 through-hole footprint enables easy hand-soldering during prototyping and fits into PCB slots reserved for traditional SIP-format DC-DC modules.

Frequently Asked Questions
Why choose the RB-2412D for an op-amp supply design that needs both +12 V and -12 V rails from a 24 V bus?
The RB-2412D can provide a -12 V auxiliary output in addition to its primary 12 V output from a 24 V nominal (21.6–26.4 V) input, making it a single-component solution for split-rail op-amp biasing. This eliminates the need for a separate negative regulator, saving at least 2 additional components and reducing PCB footprint in space-constrained analog signal chain designs.
What input voltage tolerance does the RB-2412D support, and is that sufficient for 24 V battery-backed industrial systems?
The RB-2412D input range is 21.6 V minimum to 26.4 V maximum, representing ±10% tolerance around the 24 V nominal. Most 24 V sealed lead-acid battery systems and 24 V regulated bus supplies stay within this ±10% band even under heavy load, making the RB-2412D compatible with battery-backed industrial control panels and PLC auxiliary supplies.
How does the SIP-7/5 package of the RB-2412D affect board assembly compared to a surface mount DC-DC module?
The RB-2412D uses a SIP-7/5 (R-XSMA-P5) through-hole pin-in-hole package with 5 or 7 pins that insert into drilled PCB holes and solder from the bottom side. Unlike surface mount modules, this allows hand-soldering without a reflow oven and provides stronger mechanical retention against vibration, which is advantageous in industrial environments with frequent shock loads.
