描述
This device combines a current transformer (CT), transducer and high current output relay together to switch alarm circuits, contactors and most resistive or inductive loads. The LSRX can perform the function of an auxiliary contact, yet has the advantages of universal application and isolation.

LSRX / LSRX-C SERIES

Self-powered load sensor, low-cost

proof relay

Description

The LSRX/LSRX-C Series are AC current sensors designed to

energize the output contact whenever 4.5 Amps or greater is

present. The LSRX/LSRX-C Series is used commonly as an AC

current proof relay to indicate if a motor is operating. It can also

be used to interlock fans, compressors and motors; to indicate

equipment status such as feed rates, tool wear, loss of prime

on pumps, mixer viscosity and all types of current sensing

conditions or to stage pump motors, chillers, or other machinery.

This device combines a current transformer (CT), transducer

and high current output relay together to switch alarm circuits,

contactors and most resistive or inductive loads. The LSRX/

LSRX-C Series can perform the function of an auxiliary contact,

yet has the advantages of universal application and isolation.

Features & Beneﬁts
