Explore our CE, UL, and RoHS certified solid state relays and power switching contactors engineered for seamless integration into Austrian control cabinets and PCB power boards.
In modern industrial electronics—spanning Upper Austria’s robotics manufacturing, Styria’s automotive powertrain testbeds, and Tyrol’s commercial heat pump systems—the transition from traditional electromechanical relays (EMRs) to solid state relays (SSRs) has become standard practice. PCB Mount Solid State Relays represent the apex of silent, contactless semiconductor switching, providing infinite cycle lifetimes, zero contact bounce, and immune performance in high-vibration alpine industrial settings.
Unlike electromechanical relays that rely on physical silver-alloy contacts prone to arcing, oxidation, and acoustic noise, PCB mount SSRs utilize an internal infrared light-emitting diode (LED) coupled with an optical sensor (phototriac or phototransistor array). When a low-voltage DC logic signal (typically 3–32 VDC from a PLC or microcontroller) energizes the input LED, the emitted light triggers the gate of the output semiconductor device without electrical contact.
For AC load switching across Austria's 230V/400V 50Hz grid, our Zero-Cross Turn-On SSRs eliminate electrical noise (EMI) by delaying conduction until the AC line voltage passes through the 0-volt threshold. This minimizes voltage transients ($dv/dt$) and surge currents ($di/dt$), making them ideal for resistive heating elements, solenoids, and sensitive medical instruments in accordance with European EMC Directive 2014/30/EU.

| Operational Lifetime | > 100 Million Cycles (No Wear) | > 100 Million Cycles (No Wear) | 100,000 to 500,000 Cycles Max |
| Vibration Immunity | 10–500 Hz, 20G (Fully Epoxy Potted) | 10–500 Hz, 20G (Fully Epoxy Potted) | Susceptible to False Contact Opening |
Because solid state switching semiconductors exhibit a constant forward voltage drop (typically 1.1V to 1.6V across a TRIAC or SCR during conduction), thermal management on the printed circuit board is critical. Power dissipation ($P_D$) can be calculated using the formula:
To prevent thermal runaway and maintain junction temperature ($T_j$) below the 125°C limit, our engineering team in China designs PCB mount SSR packages with integrated high-conductivity copper leadframes and aluminum nitride (AlN) substrate insulation. When integrating our SSRs into your Austrian PCB layout, observe the following rules:
Exporting industrial control equipment to Austria requires full compliance with European Low Voltage Directive 2014/35/EU and harmonized safety standard EN 60947-4-3 (AC semiconductor controllers and contactors). Our PCB mount SSRs are engineered with enhanced isolation barriers providing > 8.0 mm creepage and clearance distances across the DIP, SIP, and SMT package footprints, satisfying Overvoltage Category III and Pollution Degree 2 requirements under ÖVE / EN guidelines.
From industrial automation corridors in Linz to smart building manufacturers in Graz and energy plants in Vienna, our PCB SSRs provide optimized switching power.
Upper Austria is the mechanical engineering heartland of the country. In automated assembly lines, robotic arms, and CNC controllers, our micro-DIP PCB SSRs act as ultra-fast I/O interface modules between 24V PLC outputs and field actuators. Zero contact wear guarantees 24/7 continuous operation without downtime for maintenance.
With Austria's strict building energy performance regulations, heat pump manufacturers require completely silent, high-reliability SSR switches for compressor heaters, valve actuation, and circulating pumps. Our zero-cross PCB SSRs eliminate acoustic clicking sounds inside residential and commercial indoor units while delivering high surge current resistance during cold motor startups.
Styria’s green tech cluster demands high-voltage isolated switching components for Battery Management Systems (BMS), solar inverters, and DC fast-charging stations. Our high-voltage DC PCB relays and heavy-duty contactors handle high surge currents, pre-charge isolation, and emergency battery disconnect functions with low power dissipation.
Biomedical equipment and laboratory incubators require precise PID temperature control loops without line harmonic interference. Our random turn-on and phase-angle controlling PCB SSRs enable continuous analog heating control with millidegree stability while maintaining low leakage currents compliant with IEC 60601-1 safety limits.
Key economic, regulatory, and technological shifts shaping the demand for high-reliability Chinese SSR electronics in Austria.
Austrian OEMs are replacing electromechanical contactors with high-density PCB SSRs integrated directly into embedded smart sensor boards. Microprocessor-compatible 3.3V/5V DC inputs allow direct MCU control without intermediary buffer relays, lowering total system bill-of-materials (BOM) cost.
Austrian environmental laws strictly enforce EU REACH candidate lists and RoHS 3 (Directive 2015/863) lead-free, flame-retardant material requirements. Our factory utilizes UL94 V-0 epoxy potting resin and 100% lead-free SMT solder paste across all production lines.
Under Austria's "Raus aus Öl und Gas" incentive scheme, heat pump installations are surging. Compact PCB mount solid state relays provide silent zero-cross heating switching with operational lives exceeding 15 years, matching the mechanical lifespan of the heat pump compressor.
As a specialized China-based manufacturer of solid state relays, DC contactors, and EMI filtering components, we combine high-volume production scale with rigorous OEM custom engineering support for European partners.
Our factory operates high-speed Yamaha and Fuji surface mount technology (SMT) lines with 3D Automated Optical Inspection (AOI) and X-ray void analysis for void-free solder connections under high-power SCR chips.
We supply drop-in replacements for obsolete or long-lead European competitor part numbers (SIP, DIP, mini-puck), adjusting pin pitch, height profiles, and internal coil drive thresholds per your mechanical drawings.
Every shipment to Austria is accompanied by CE Declarations of Conformity, UL Recognized component files, RoHS/REACH compliance certificates, and full batch test documentation (Dielectric, Contact Drop, dv/dt).
