Grundfos IO101 SQFlex Switch Box

Grundfos SQFlex Switch Box

The Grundfos IO101 is a dedicated interface and control accessory designed for use with the SQFlex pump system, providing a simple and reliable way to manage pump operation through external signals and switches. Compatible with the full SQFlex lineup, the IO101 allows users to connect float switches, pressure switches, and other external control devices to automate pump start/stop functions — making it an essential component for tank-fill applications, livestock watering systems, and any off-grid installation where hands-free, automatic water management is required.

Engineered to integrate seamlessly with the Grundfos CU 200 control unit, the IO101 Switch Box expands the functionality of an existing SQFlex system without adding complexity to the installation. Its rugged, weatherproof construction makes it well-suited for outdoor and remote environments, and its straightforward wiring interface ensures a clean, professional installation for both new systems and retrofits.
