The GRT8-S1 is an asymmetric cycle time relay (also called an "alternating relay" or "flip-flop relay") produced by Geya Electric. It's designed to control two loads alternately, switching between them based on time intervals or external triggers.
Key Features of GRT8-S1:
Asymmetric Cycling:
Alternates between two outputs (e.g., Load A and Load B) with independent ON/OFF times.
Example: Load A runs for 5 sec → OFF → Load B runs for 10 sec → OFF → repeats.
Adjustable Timing:
Time ranges typically from 0.05s to 100h (depends on model).
Settings via potentiometers or dip switches (varies by version).
Control Modes:
Auto-Cycle: Continuous alternating operation.
Triggered Cycle: Switches outputs on each external signal (e.g., push button, sensor).
Applications:
Pump/motor alternation (prevent wear).
Lighting control (e.g., alternating streetlights).
Industrial automation (e.g., dual-compressor systems).
Wiring Example (Typical Setup):
Power Supply ──┬── COM (Relay)
├── Input (Trigger, if used)
Load A ───────┴── NO (Normally Open)
Load B ───────┴── NC (Normally Closed)
(Check the datasheet for your specific model’s pinout.)
Troubleshooting Tips:
No Switching? Verify timing settings and trigger signals.
Inconsistent Cycles? Check for voltage fluctuations or incorrect load wiring.https://store.unigulfsupply.com/product/asymmetric-cycler-time-relay-grt8-s1-geya/
