The Model LSRX
is an AC current sensor designed to energize the
output contact whenever 4.5 Amps or greater
is present. The LSRX 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 can
perform the function of an auxiliary contact,
yet has the advantages of universal application
and isolation.
For more information see:
See Appendix A, page 70, Figure 15 for dimensional
drawing.
