Timer Relays
GEYA GRT8 relay series automatic switching device that uses electromagnetic (or mechanical) principles to achieve time-delay control. Its core function is to achieve time-delay on/off or sequential control of the circuit through preset time.
- Setting methods: Knobs, DIP switches, digital displays, buttons, WiFi, Bluetooth, etc.
- Ultra-wide operating voltage: AC/DC 12-240V
- Ultra-long latency range: 0.1-100 days
- Supports the use of additional accessories such as controllers, contactors, and sensors.
Current Monitoring Relays
GEYA GRI8 series ensures circuit safety by monitoring AC/DC current flow. It is crucial for preventing motor overload, pump dry-running, and heating element failures.
- Versatile Monitoring: Measures AC/DC current range 0.05A~16A directly.
- Smart Protection: Detects Overcurrent, Undercurrent, and Window modes (High/Low limits).
- Contactless Option: Available in through-hole design for safe, non-invasive sensing.
- Easy Installation: Universal DIN-rail mount with simple knob settings.
Voltage Monitoring Relays
GEYA GRV8 series monitors power supply stability to protect industrial equipment. It automatically disconnects circuits upon detecting voltage faults, ensuring system safety and longevity.
- Comprehensive Protection: Monitors Over/Under voltage, Phase Failure, Sequence, and Asymmetry.
- Wide Compatibility: Supports DC, Single phase AC, and 3 Phase (3 wire/4 wire) systems.
- Adjustable Precision: Features knob-adjustable voltage thresholds and delay time (0.1s~10s).
- Compact Design: Space-saving 18mm width with clear LED status indicators.
Other Functional Relays
GEYA relays, building upon their existing strengths, have added additional modules such as probes, contactors, and controllers to expand their unique functionality.
We consistently aligns with market demands for functionality, usage scenarios, and connection burdens, winning customer trust through cost-effectiveness and precise selection.
