In a bustling German automotive parts factory, a production line that used to experience 3-4 unexpected shutdowns monthly now runs flawlessly. The secret? Engineers replaced traditional electromagnetic relays with FERRAZ H220071C PS271PRE solid state relays (SSRs). This unassuming 40mm x 20mm device has become the new workhorse in industrial control systems.
Precision Meets Durability
The H220071C’s 3-32VDC input range allows seamless integration with modern PLC systems, while its 10A load capacity handles most motor control applications. Unlike mechanical relays that last about 100,000 cycles, FERRAZ’s optical isolation technology enables 10 million operations – equivalent to 11 years of continuous 1-second switching.
“Our energy consumption dropped 15% after the switch,” reports plant manager Hans Weber. “The zero-crossing detection eliminates arcing, making it safer for our dust-heavy environment.”
Real-World Impact
In Barcelona’s solar farm project, 800 units of H220071C manage inverter banks with 0.8ms response time – 60x faster than mechanical alternatives. This speed prevents 2-3% energy loss during cloud transitions, translating to 12MWh annual savings per installation.
- IP67-rated housing withstands -40°C to 85°C
- 1.5kV isolation voltage ensures safety
- RoHS-compliant construction
From food packaging machines requiring precise temperature control to EV charging stations demanding silent operation, this SSR proves that reliability isn’t about making noise – it’s about consistent performance when it matters most.
