1
Relay group-to-group isolation separates line voltage from SELV/PELV and separates different phases up to 250 VAC
line to ground.
2
For CPU models with relay outputs, you must install a digital signal board (SB) to use the pulse outputs.
3
Depending on your pulse receiver and cable, an additional load resistor (at least 10% of rated current) may improve
pulse signal quality and noise immunity.
4
External overload protection is to limit fire hazard. Overload can damage relay or transistor output.
