Photo-relays have really come on

7:03 am PST, February 17, 2020

Seeing these new photo-relays from Toshiba reminded me when I first noticed optically-isolated mosfet switches. They they were really for signal switching, or for a few dozen mA, maybe at 30V – telephone stuff. At the time, my task was to switch 500mA and so a couple of discrete mosfets and a transformer-rectifier gate drive were ...

Toshiba announces trio of high-current 1-form-A photorelays

3:54 am PST, February 17, 2020

Toshiba has announced three photorelays that are aimed at applications where they will replace mechanical 1-form-A relays in industrial and factory automation installations. Based upon the U-MOS IX semiconductor process with a trench structure, the TLP3106A, TLP3107A and TLP3109A have RON(max) values of 30mΩ, 40mΩ and 65mΩ respectively. They offer options including an off-state output ...

No-added-solvent conformal coating can be sprayed, and dries in seconds

3:47 am PST, February 17, 2020

Dow has introduced a solvent-less but sprayable silicone conformal coating that cures in seconds under UV light. Called Dowsil CC-8030, it is a one-part product that also includes moisture-cure for the nooks and crannies that UV cannot reach so well. “Other silicones support UV curing, but none are conformal coatings with a low enough viscosity for spray ...

Analogue dc motor control

3:07 am PST, February 17, 2020

I was planning to use the opto-coupler speed sensor as part of a motor speed control – making the motor into the VCO block in a phase-locked loop. When this technique works, using it is simple: put frequency wait for lock get motor speed proportional to input frequency But my spare HC4046 PLL chip appears to ...
