PCB AC Load SSR with DC control - del30010This is a PCB Mount SSR for Control of a Small AC load
like a Lamp or a Contacter. It has Optical Isolation and has a
Thyristor for output. The MOC3041 A zero crossover optical triac driver
is used here. The footprint is very small, many can be stacked in one
small PCB. These can be used to signal bigger loads or devices.
They can take upto 2 A, so small heaters or motors can be switched. It
is better to use a fuse in series with the output as a defective load
can blow the SSR.

The Sticker below was put on the side of the SSR, All components on this card have to be within 5mm or bent within that. This was due to the fact that the can was around 8mm thickness. The pin details of devices are also shown below.   The PCB samples are shown here, The thyristor needs a bigger PTH hole. These details you have to give when ordering boards. Drilling later will remove PTH and circuit is broken. The boards below needed rework. The PCB's should be used without any filing and drilling at your end. Also never do any mechanical work on cards-products after fabrication. I have seen people sawing-filing finished products. This leads to reliability problems. ; - ). See in the bottom PCB, the top cutting edge has a track which can short. See basics of PCB here How to Create a Printed Circuit Board. pdf   |
