Solid State Relays
Rockwell
Automation has broadened its Allen-Bradley relay product line
to include six new solid-state relays (SSRs). The solid-state
relay logic input control levels are compatible with many industrial
controllers available in today’s market such as PLCs and
temperature controllers. The switching design of the solid-state
relay uses no moving parts or contacts that can wear out. This
is one of the reasons they will perform in a variety of harsh
environments.
Long Life Expectancy
Solid-state relays use electronic instead of
mechanical devices for load switching while providing a life cycle
expectancy of approximately 100,000 energized hours or 11.4 years.
This reduces product replacement and downtime.
Low Maintenance
There are no moving parts or contacts to wear
out or be affected by vibration and shock. Maintenance dollars,
parts replacement, and downtime are reduced drastically, if not
eliminated altogether.
Reduced Power Costs
The solid-state relay typically requires 25
times less power than electromechanical relays and also generates
less heat. This means the panel can typically be smaller, reducing
panel space requirements.
Flexibility
Plug-in style SSRs (700-SA, SC, SF and SK)
are compatible with Allen-Bradley 700-HN sockets and retainer
clips. In addition, the 700-SA SSR is compatible with the 700-HT1
multi-function, multi-range timer module while the 700-SC SSR
is compatible with the new 700-AT1 or 700-AT2 timer modules. The
flexibility and compatibility with these relay accessories support
a wide range of applications, while reducing spare parts inventories.
