DVANTAGE
Omron has been leading the world in relay technology for more than 50 years, maintaining the industry’s broadest relay
product line. Our large, dedicated relay R & D budget allows us to produce a steady stream of innovative relays that
perform in different operating environments and industries. Companies around the world depend on Omron to provide
ingenious solutions to their most challenging applications, including applications ideal for solid state relays.
Our line of solid state relays includes more than 20 different models with hundreds of variations and options. These relays
have flexible input and output ranges and multiple footprints providing a reliable solution to any application.
Benefits of
Solid State Relays
Have a life expectancy significantly
greater than electromechanical relays
Have no moving parts or contacts to
wear out
Are immune to contact bounce
and arcing
No audible clicking
Generate very little electromagnetic
interference, providing clean switching
for virtually any load
Have up to 10 times the shock resistance
of electromagnetic relays
Have high I/O isolation that is crucial for
isolating sensitive equipment from the
load
Can be switched ON with very little input
current
Have internal circuitry that lengthens load
life
When should I use a
Solid State Relay?
When long life is required
When the relay must operate in a harsh
environment (i.e. dust, humidity, or a
combustible environment)
When silent operation is necessary
When high speed switching is required
When limited source current is available
to drive the input
When compatibility with digital logic is
required, such as with microprocessor or
computer controlled applications
If reduced electromagnetic interference is
required
When the application requires a high
number of operations

Omron’s Solid State I/O modules are electronic devices
providing an interface between a logic circuit and external
devices. These devices are compatible with many
microprocessors, TTL and MOS type logic systems. Input
modules convert AC or DC inputs from external devices like
switches or sensors into acceptable DC current and voltage for
the logic circuit. Output modules use the output of the
processor to switch external AC and DC loads like motors or
solenoids on and off.
Omron’s G3TB uses the industry standard color-coding system,
ensuring easy differentiation among inputs and outputs and is
perfect for PCB mounting applications. Omron’s G3R I/O
module is ideal for industrial applications with space
constraints. It shares the G2R’s footprint, is clearly marked per
input/output function and can be mounted side-by-side on a
DIN rail or panel using the P2RF socket.
