Check-It™ Duplex Control Panel
The Alderon Check-It™ Duplex Control Panel is designed to control and monitor a pump station with two submersible pumps in demand dose applications. It features an automatic alternating relay that balances pump run times each cycle, supports up to five float switch inputs for advanced level monitoring, and includes Alderon’s one-touch self-diagnostic system. The heavy-duty NEMA 4X enclosure, IEC motor contactors, and built-in dry contacts make it a complete, field-ready solution for duplex lift stations and pump chambers.
