  • RECOMMENDED OPERATING CONDITIONS Please following conditions to ensure proper device operation and resetting. Item Symbol Recommended value Unit Input LED current IF 5~10 mA Short-circuit protection function When the load current exceeds a fixed value, the short circuit protection function activates to completely cut off the load current and keep the Photo MOS Relay turned off. In the Photo MOS Relay ,The short circuit protection instantaneously completely cuts of the load current. This function protects any circuits that follow the Photo MOS Relay from excess current and prevents it from becoming damaged. Turn off the input current, and restart, Photo mos relay function to restore. To make the short circuit protection complete, make sure that the input current is at least I F = 5 mA.
