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.
