We Design. We Build. We Deliver.
Engineered for high-density printed circuit boards, industrial HVAC, DIN rail automation, and high-voltage DC distribution across German manufacturing sectors.
In the highly automated manufacturing ecosystem of Germany—spanning from Baden-Württemberg's precision engineering hubs to Bavaria's automotive assembly plants—the demand for ultra-reliable, arc-free power switching has reached an unprecedented peak. As electromechanical relays (EMRs) hit physical limits regarding switching frequency, acoustic noise, contact bounce, and mechanical wear, CE certified PCB Mount Solid State Relays (PCB SSRs) have emerged as the foundational standard for modern power control architectures.
This technical whitepaper provides German hardware design engineers, systems integrators, electrical component buyers, and compliance directors with an exhaustive guide to selecting, integrating, and specifying PCB-mounted semiconductor relays. Built to meet stringent European safety directives—including the Low Voltage Directive (LVD 2014/35/EU) and EMC Directive (2014/30/EU)—our portfolio supplied through Altran Magnetics bridges the gap between high-power handling and sub-compact printed circuit board layouts.
Integrated zero-cross detection algorithms minimize electromagnetic interference (EMI) during AC resistive and inductive load switching, allowing immediate compliance with CE and CISPR 11 Class B standards.
Featuring reinforced optical isolation layers capable of resisting up to 4,000 Vrms dielectric breakdown voltage between low-voltage microcontrollers (PLC I/O) and high-voltage AC/DC power buses.
Utilizing back-to-back SCR output structure coupled with direct copper bonded (DCB) ceramic substrates to optimize heat transfer directly into PCB copper planes or compact heatsinks.
Unlike panel-mount relays that require external wire harnesses and bulky chassis enclosures, PCB mount solid state relays integrate directly into target circuit cards. The internal architecture consists of three primary isolation and power stages:

Understanding regional industrial specialization in Germany allows Altran Magnetics to provide tailored technical support for localized PCB SSR applications:
In machine-building regions such as Stuttgart and Dortmund, control cabinets require high-density I/O switching. PCB-mounted SSRs isolate sensitive microprocessors from heavy inductive solenoid valves and motor starters without generating electro-mechanical click noise or contact erosion.
With electric vehicle (EV) manufacturing centered in Munich, Ingolstadt, and Wolfsburg, high-voltage DC relays and PCB SSRs are used in automated test stations (EOL testing) for lithium-ion battery management systems (BMS) and onboard charger (OBC) simulation setups.
Plastic extrusion, injection molding, and packaging machinery rely on precise PID temperature control loops. Zero-crossing PCB SSRs switch resistive heating elements millions of times annually without degradation, holding temperature tolerances within ±0.1°C.
Compliant with DIN EN 60601-1 safety requirements, low-leakage-current PCB SSRs are integrated into dialysis machines, blood analyzers, and incubators where quiet switching, optical isolation, and medical-grade reliability are mandatory.
Navigating the German electronics market requires strict compliance with evolving EU legislation and national standardization guidelines driven by the DKE (Deutsche Kommission Elektrotechnik Elektronik Informationstechnik) and VDE Institute:
The German Energiewende initiative emphasizes extreme energy efficiency across electrical infrastructure. Mechanical contactors consume continuous power to keep electromagnetic coils energized (often 2 to 10 Watts per device). In contrast, advanced PCB Solid State Relays require minimal input drive power (< 0.1 Watt LED drive stage), resulting in massive cumulative energy savings across large industrial installations.
As factory space in Germany comes at a premium, panel builders are shifting away from traditional DIN-rail heavy enclosures toward high-density PCB-integrated power boards. Our PCB SSRs offer footprint reductions of up to 70% compared to traditional panel-mounted contactors while maintaining robust 4kV surge isolation.
All PCB SSR products supplied for the German market undergo strict chemical material audits. We issue full documentation certifying zero heavy metals (lead, mercury, cadmium, hexavalent chromium) and no Substances of Very High Concern (SVHC), simplifying customs clearance through German ports such as Hamburg and Bremerhaven.
Altran Magnetics, LLC brings decades of power electromechanical and semiconductor engineering expertise to global OEMs. By partnering with our engineering team, German manufacturers gain a distinct operational advantage:
If your legacy PCB design requires non-standard terminal spacing, custom pin lengths, or specific gate trigger thresholds, our engineering team modifies standard layouts to create a seamless drop-in replacement under full engineering revision control.
Every single PCB SSR undergoes 100% automated functional testing—including dielectric withstand, input threshold voltage check, and on-state voltage drop measurement. Every production lot is laser-coded for end-to-end supply chain traceability.
We supply complete engineering support files to accelerate your CE marking process: 3D STEP models, high-resolution thermal derating curves, VDE/CE certificates of conformity, and detailed circuit design guidelines.
Here are direct technical answers to common questions raised by buyers and engineers across the DACH region (Germany, Austria, Switzerland):
Our PCB Solid State Relays are designed and tested in strict accordance with EN 60947-4-3 (Low-voltage switchgear and controlgear - AC semiconductor motor controllers and contactors) and EN 60950-1 / EN 62368-1 for equipment safety. Declarations of Conformity (DoC) covering LVD 2014/35/EU and EMC Directive 2014/30/EU are provided with standard sampling packages.
When switching current loads above 3 Amperes RMS, thermal management on the PCB becomes critical. Designers should allocate sufficient copper foil area (preferably 2 oz or 3 oz copper weight) around the load terminals, utilize thermal vias to transfer heat to bottom ground planes, or attach compact clip-on aluminum heat sinks. Our datasheets provide precise Thermal Junction-to-Ambient resistance ($R_{th,j-a}$) values to streamline your layout calculations.
Zero-Cross SSRs turn ON only when the AC sinewave voltage crosses zero volts. This dramatically minimizes electrical noise, inrush current, and EMI, making them ideal for resistive heating elements and capacitive loads. Random Turn-On SSRs turn ON immediately upon receiving an input signal (within microseconds), making them ideal for phase-angle control, dimming applications, and precise inductive load timing.
Yes. Our application engineering team in Sterling, Illinois, works directly with German procurement teams to cross-reference legacy or phase-out part numbers from brands like Sharp, Omron, Crydom, Celduc, and Teledyne. We supply detailed pin-to-pin functional mapping and sample units for rapid bench testing.
We accommodate various Incoterms including EXW, FOB, and DDP (Delivered Duty Paid) to major German logistics hubs. All shipments include standard commercial invoices, packing lists with clear HS Code classifications (e.g., HS 8536.41 / HS 8536.49), Certificate of Origin (COO), and RoHS/REACH compliance paperwork for seamless customs clearing.
Because PCB SSRs are completely solid-state devices fully encapsulated in epoxy resin with zero moving internal parts, they exhibit extreme resistance to mechanical shock and vibration. They are ideally suited for mobile machinery, railway sub-assemblies, and industrial environments subject to constant mechanical stress where electromechanical relays suffer from contact chatter or early mechanical failure.
