NO AC Load SSR with DC control - del30009
This is another PCB Mount SSR or Solid State
Relay. Can Go a bit better on the Amps than the
Slim PCB-SSR shown earlier, which is more of an
I/O Module for interface from digital circuits to
contacters. This circuit is the same, a bigger
box, with a alumina filled epoxy and a Small
Aluminum plate on top, this way more Load is
Here is an Embedded System that could make use of
such Relays -
CAn Remote Automation-Control with AVR
This ability to carry more load, does not depend
on circuit, yes the tracks have to be reinforced
by copper braid for higher currents. Or thick
copper strands. The main issue is to get the heat
off the BTA16-600 Triac.
16A 600V is good, provided load short circuit is
avoided, inductive loads are taken care of. and
the heat from triac which increases with more
current. has to be pumped out from the aluminum
plate to surrounding air.
You certainly need to know about the "The Seniors"
Relays and Contactors.
This is a SSR that was custom made as a Stackable
Output Module. It is maent for PC Mount low
current applications and generally drives an
external Contacter to Power the Motors or Heaters.
Now the Silpad or Mica can be Avoided for
BTA16-600 Type of devices, (see datasheet) The
Metal tab or sometimes a Non-metal tab of other
devices offer kilo-volts of insulation. You can
take extra precaution with mica-silpad or a thin
layer of thermally conductive epoxy. But this will
reduce its Amps or Load abilities.
In a SSR the circuit is not everything, the PCB,
the engineering, the production, testing will
ensure you can give rugged industrial grade
