EN 954-1

• Solid state outputs
• Operation for two and three phase systems.
• Easy integration in Star and Delta wiring.
• Clear LED status of all in and outputs.
• Standstill can be monitored even when there is no space to install a sensor.
• No sensor required. G9SX-SM detects back electromotive force (BEMF) generated when the motor rotates identifying when the motor is rotating or in standstill.
• Ready to use standard configuration. No sensitivity adjustment required. User configuration is also available for fine tuning (manual adjustment).
• Applicable to inverter controlled systems.
• Can be used with an inverter, no malfunction due to the inverters dynamic brake or auto-tuning functions.
• No difficult settings required.
• Covers all standard applications.
