FEATURES/BENEFITS
• Designed for all types of loads
• Dual output (two relays in one package)
• Faston terminals
• Connector for common or individual control
• Tight zero-cross window for low EMI
• High immunity to surges
DESCRIPTION
The Series SD dual-phase relays are designed for all
types of loads. The design incorporates two relays in
a single package. The relays utilize optical isolation
to protect the control from load transients. High-
current models are excellent for motor and phase
angle control. The 50A 600 Vac models are available
with common control connector or individual control
connector. Applications include motor control, heating
control, uninterruptible power supplies, light dimmers,
industrial and process control, and on/off controls of
AC equipment.
APPROVALS
All models are UL recognized.
UL File Number: E128555.
