BS\032003\Q1
4A to 600 Vac SIP Package
DC Control
FEATURES/BENEFITS
•Industry standard package
•High in-rush capabilities
•Low input current draw
•High dv/dt capability
DESCRIPTION
The BS 4-amp solid-state single inline (SIP) four-pin
relays are designed for mounting on a printed circuit
board. The BS relays can withstand very high current
overloads. The compact size and triac output make
the BS relay an excellent choice for switching medium-
power resistive loads.
APPLICATIONS
•Interface applications
•Vending machines
•Light/lamp control
•HVAC controls
APPROVALS
All models are UL recognized. VDE approved.
UL File Number: E128555.
