Pentair RLYLX 20-Amp Relay Kit (DPST) – Replacement High-Voltage Power Relay for Pool & Spa Automation
The Pentair RLYLX is a replacement 20-amp power relay kit used in compatible Pentair/Compool pool and spa automation power centers. This relay switches high-voltage loads (such as pumps, lights, blowers, or other auxiliary equipment) on and off from the automation controller. Replace it when a circuit stops switching reliably, sticks on/off, or shows signs of heat damage at the terminals.
Key Specifications
- Part Number: RLYLX
- Relay Type: DPST (Double Pole, Single Throw)
- Max Current: 20A
- Typical Use: High-voltage switching relay inside automation load centers/power centers
- Typical Limits (application-dependent): Up to 3 HP pump loads; up to 1000W lighting total (500W per pole)
- Wiring Notes: Terminal blocks commonly accept up to two 12 AWG conductors per screw (verify your installation requirements)
Common Applications
- Replacement relay for Pentair/Compool automation systems that use standard 20A DPST load relays
- Switching auxiliary circuits such as pool/spa pumps, booster pumps, lights, water features, blowers, or other controlled loads
Common Symptoms of a Bad Relay
- Equipment won’t turn on/off from the automation panel or schedule
- Relay chatters or clicks repeatedly while trying to engage
- Circuit sticks ON or OFF even when commanded
- Burn marks, melted plastic, or heat-discolored wiring/terminals at the relay
Important Safety Note
- This is a high-voltage electrical component. Power should be shut off at the breaker, and installation should be performed by a qualified technician/electrician as needed.
- Always confirm your automation model and the relay type/amperage required before ordering.

Installation & Maintenance Tips
- If a relay failed due to heat, inspect for loose terminals, corrosion, or undersized wiring that can cause overheating.
- After replacement, run the load and check that the relay stays cool and the circuit switches cleanly without chatter.
- Keep the automation enclosure dry and sealed; moisture and corrosion can shorten relay and terminal life.
- If multiple relays are failing, verify the controlled load is not exceeding relay ratings and that supply voltage is stable.
