● The digital signal interface supports two types of signal relays: dry contact relays that support signal relays and wet contact (pulse) relays that support opto-MOS relays.
● The digital signal can be configured as 1 channel unidirectional/2 channels unidirectional/4 channels unidirectional/1 channel bidirectional/2 channels bidirectional mode.
● It can automatically detect the status of the input digital signal, whether it is normally open or normally closed. The output digital signal will be in the same status as the input signal, which makes it convenient for engineering commissioning.
● It can maintain stable output digital signals for all other channels even when it is powered on or when there is no fiber optic cable plugged in, ensuring that they will not switch on or off randomly.
● Each channel has indicator lights for open and closed digital signal states.
● The digital signal interface is designed to meet the IEC61000-4-5 (10/700μS) standard for lightning protection, with a differential mode surge immunity of 6KV with a 2Ω impedance and a common mode surge immunity of 6KV with a 2Ω impedance.
