Solid stare relay (triac) question.

[David Nugent]

I have a crydon solid state relay (a0241). Triac output.

My question is:

It has 4 leads.

2 are +, - (Control Lines) - DC turn on voltage
2 are AC/LOAD

Does it matter how I hook the AC/LOAD ones up? When I look at their data
sheet for the product, the picture on the data sheet shows AC/AC on the 2
leads, not AC/LOAD.

Thanks,
Dave

The AC/LOAD terminals must be connected in series with the load and
the AC line. The polarity is not real important. Some applications
put it on the hot side of the load, so that the disenergized load does
not see dangerous voltage. But a TRIAC relay is not satisfactory as a
safety disconnect switch, so you should not feel safe working on the
load, just because the relay is off. It works just as well on the
neutral side of the load.
