manual fgs-222 incomplete ??






Because there is no diagram in the manual of fgs-222 concerning the issue (why??? for another device there was), hereby my question.

Can I use 2 voltages on this device?


- 's1' (via some switch SW) connected to 'l' of 230v ac

- 'l' en 'n' connected to 230v ac

- 'in' and 'q1' connected to 8v ac

So, when s1 detects a voltage of 230v (SW is turned on), I can turn the 8v current on running from 'in' to 'q1'.


Thanks in advance,

Sander Advokaat

Yes this is possible.

Generally it is good practice to keep voltages

well separated and those terminals on fgs 222

are very close.

A safer option is to slave a second  dumb relay

which gets switched by fgs222  240 v and in turn switches your low voltage circuit, more expensive but safer, then your low voltage wires and connections will be well seperate from the mains voltage.

however your proposal will still work as you described

if you search in the forum this has beed discussed many times.,
