What kind of output is on this PID Controller
It looks to me like OUT1 is a SPDT relay contact and OUT2 is a SPST relay output.

SPDT means single pole double throw i.e. a changeover relay contact

SPST means single pole signle throw i.e. a normally open relay contact.

Both relay contacts can be presumed to be able to work with a 250VAC AC connected load at up to 3 amps but, without the exact model number and technical manual this is still a bit of an assumption.
