Opto Isolator Connection

For volts-free signal (switch) there is no requirement for Opto Isolator and the switch can be connected

directly to the inputs marked on the PCB as Opto 4 & Opto 5. For a 12-24V DC signal or 24-230V AC

signal unit, the signal MUST be connected via the Opto Isolator(s) supplied with the unit.
