Solid-state Relays

No-contact relays that semiconductor is utilized, which enables high-speed and high-frequency operation. OMRON provides Solid-state Relay for enormous range of applications.

For Heater Control

These Relays enable high-precision, high-frequency temperature control for reflow ovens, molding machines, and sintering ovens. Models are available with fault detection and cyclic control.

  • G3PH

    High-power, Load-control SSRs with High Current of 75 or 150 A and High Voltage of 240 or 480 VAC.

  • G3PF

    A New-concept SSR with Built-in Current Transformer. Heater Burnout and SSR Shortcircuit Failure Detection.

  • G3PE (Single-phase)

    Compact, Slim-profile SSRs with Heat Sinks. Models with No Zero Cross for a Wide Range of Applications.

  • G3PE (Three-phase)

    Compact, Slim-profile SSRs with Heat Sinks. Solid State Contactors for Three-phase Heaters Reduced Installation Work with DIN Track Mounting.

  • G3PA

    Extremely Thin Relays Integrated with Heat Sinks

  • G3PC

    Detects failures in SSR used for heater temperature control and simultaneously outputs alarm signal. This SSR supports the safe design of heater control systems, and contributes to maintenance improvements by the user.

For Three-phase Motors

OMRON Solid-state Contactors provide smooth starting and stopping functions to suppress sudden motor operation and thus reduce mechanical stress. They are ideal for conveyor belts and other applications requiring smooth movement.

  • G3J-T-C

    New Models with AC Power Supply Input and Monitor Output Equivalent to Non-contact SPST-NO Join the G3J-T Series.

  • G3J-T

    Soft-start/stop Function Starts and Stops Three-phase Motors Smoothly and Economically.

  • G3J-S

    Soft-start Function Starts Motors Smoothly and Economically.

  • G3J

    Solid State Contactors That Can Drive 3-phase Motors Frequently, and Achieve Harmonized Protection with Thermal Overload Relays.

Socket / Plug-in Type

These Solid-state Relays have the same shape as OMRON's general relays such as MY, LY, MK, G2R and G7T, and are suitable for high-frequency switching, signal exchange with controllers, and other I/O applications.

  • G3B / G3BD

    International Standards for G3B Series,Same Profile as MK Power Relays.

  • G3F / G3FD

    International Standards for G3F Series, Same Profile as MY Power Relays.

  • G3H / G3HD

    New Models with International Standards Added to G3H Series (-VD in model number). Same Profile as LY1 and LY2 Bi-power Relays.

  • G3TA

    I/O SSRs That Mount to OMRON's G7TC I/O Block.

  • G3FM

    100-μA-max. Leakage Current, No Bleeder Resistor Required.

  • G3R-I/O

    SSR with Plug-in Terminals The Same Shape as the G2R-1-S Power Relays.

Other Solid State Relays

A complete lineup of no-contact semiconductor relays for PCB mounting.

  • G3S / G3SD

    Ultra-small Relay Breaks up to 1 A
