Sentinel Kinetic Opto-coupler for Volt-free BMS Connection
The LED terminals are intended to drive a remote LED to indicate that a fault has occurred. They provide an LED driving signal output between the + and terminals that enables remote indication of a unit fault.
This signal could also be used by a BMS system so that it is informed that a fault has occurred.
If a volt-free contact is required then use this opto-coupler to provide electrical separation.
