DataView™ LI55 Level Controller





The general purpose level controller displays engineering units with one 4-20 mA or 0-10 VDC continuous level sensor input and is offered in three configurations with optional 2 or 4 programmable relays, and an isolated 4-20 mA repeater. Each relay can be configured on a single set point (high level alarm or low level alarm) or latched on two set points for automatic fill or empty in simplex (one pump or valve) or duplex (two pumps) level control modes.
