G9SA Safety Relay Unit — Two-Hand Controller G9SA-TH301 AC/DC24
OMRON — G9SA Series
The G9SA-TH301 is a dedicated two-hand control safety relay from OMRON's G9SA safety relay family (the same family already used for FST's existing G9SA/G9SB safety relay listings), built specifically to monitor two-hand control stations on presses and similar equipment. It requires synchronized activation of two separate operator pushbuttons to permit a hazardous machine cycle, and cancels the control sequence if only one button is pressed, per EN 574 two-hand control requirements.
Key Features
- Purpose-built two-hand control monitoring relay (2-channel input)
- 3PST-NO safety outputs (Category 4) plus SPST-NC auxiliary output
- 24 V AC/DC operating voltage
- Screw terminal wiring, DIN rail or surface mounting
- Part of the expandable G9SA safety relay platform (compatible with existing G9SA expansion units)
