Planet IDL-4802-48 Инструкция по эксплуатации онлайн [12/20] 66127

The HK circuit contains a photo coupler powered by the IDL-4802 to detect the

"open" or "close" status of the loop between HK_IN and HK_COM (users don’t

need to feed 3.3v power into the circuit). As to the alarm output, there is a relay

between ALMOUT and ALMCOM to control the status of the loop to be "OPEN" or

"CLOSE" to the alarm equipment (close between ALMOUT and ALMCOM for alarm;

open if no alarm).
