01 · Technical overview

Functional engineering application

The Heavy-Duty Solid State Relay (MPN: BLX-SSR-6100) is built for continuous-duty industrial piping, holding pressure, temperature, and cycling loads in factory installations across Kenya and East Africa.

Key technical advantages
Zero-crossing AC switching technology eliminating electrical arcing and switching noise spikes
High continuous load rating of 40A AC at voltages from 24V to 480V AC (50/60 Hz)
Wide DC logic control input: 3 to 32 V DC, directly drivable from PID controllers and PLC digital outputs
High optical dielectric isolation of 4000 V AC between input control and output load circuits
Heavy-gauge nickel-plated copper baseplate ensuring superior heat transfer to external heatsinks
Integrated bright green LED indicator showing live input control switching status
Built-in internal RC snubber network and MOV varistor protecting against transient overvoltage
Standard industrial hockey-puck footprint with clear touch-safe IP20 transparent terminal cover
Target equipment applications
Rapid PID duty-cycle pulse control of industrial heating elements (Band, Immersion, Cartridge)Plastic injection molding machine and extruder temperature control zonesPackaging machine heat-sealing jaws, flow wrappers, and shrink tunnelsIndustrial baking ovens, powder coating curing ovens, and incubators

04 · Frequently asked

Common questions on this part

Yes. All solid state relays generate heat (approximately 1.2 to 1.5 Watts per Amp switched). When switching loads over 5 Amps, the BLX-SSR-6100 must be mounted on a properly sized finned aluminum heatsink with thermal grease to prevent semiconductor overheating.

No. The BLX-SSR-6100 uses AC thyristor semiconductor outputs that naturally turn off at AC zero-crossing. It is designed strictly for AC loads (24-480VAC). Dedicated DC-DC solid state relays are required for DC loads.

Yes. The 3-32VDC input is engineered to accept the 12VDC pulse output from temperature controllers like the BLX-TC-5100 or Pixsys ATR series.

Semiconductors require ultra-rapid semiconductor protection fuses (gR or aR type) sized to the I²t rating of the relay to protect against short circuits.

Yes. Standard 25A, 40A, 60A, and 100A SSR models and matching DIN-rail heatsinks are available off-the-shelf at STARNEX.
