Series Description

The Kele UCS-421E is a solid-state device used for multistage control in HVAC systems, sequencing boilers or chillers, or floating/tri-state control of VAV boxes from a single analog signal. The UCS-421E can be used to obtain a digital output from a voltage or current producing sensor. Units may be daisy chained to provide additional stages of control, and a mounting track for easy installation.
