Constant Current Input minimizes source
current requirement (standard on D and A
inputs only)
-002 Control Status LED
-012 EZ MountTM
•
Constructed using Teledyne’s unique Fused
CopperTM process. This process yields
superior thermal impedance and power
cycling capabilities through reduced
thermal interconnections, allowing for
cooler, more reliable operation.

GENERAL DESCRIPTION
The EFR series AC Solid State Relays are designed
to control very heavy loads. Optical isolation ensures
complete protection of control elements from load
transients. Teledyne’s advanced design featuring the
Fused CopperTM process offers users superior thermal
management resulting in superior performance,
quality and reliability.
