DESCRIPTION
The BS 4-amp solid-state single inline (SIP) four-pin
relays are designed for mounting on a printed circuit
board. The relays offer built-in voltage protection
and can withstand very high current overloads. The
Series BS4 relays have a low zero-cross window. The
compact size and triac output make the BS relay the
perfect retrofit for electromechanical relays.
