The RE-440 Pilot Relay is designed to interface low level control
signals to starters and contactors. The Relay will accept 24 VAC or
24 VDC universal input. In this way, the same Relay can be used for
either input voltage. Relay is UL listed and CSA approved to switch
5 amps at 24/120 VAC. The Relay has SPDT contact arrangement to
switch a normally open or normally closed load. High inrush current
can generate spikes not only causing problems with the controller,
but also noise on other analog input lines. RE-440 has a high
resistance, low current coil to eliminate any inrush related
problems.
The most unique feature about the RE-440 is the packaging options
available. Other relays not only require expensive sockets and
mounting hardware, but also require a deep enclosure due to the
height of the relay. Also, if the relay is mounted horizontally, the
mechanical shock generated by motor starters/contactors can loosen
the relay from its socket causing intermittent problems and
rust/corrosion build up within the base. RE-440 Relay does not
require a socket or mounting hardware and is immune to mechanical
shock or corrosion related problems.
RE-440-1 can be easily installed in a panel with the bracket
provided. The overall size of the Relay is such that it occupies
minimum space and, if necessary, can be snapped into an industry
standard 31/4" snap-track. An LED indication is provided to signal
the status of the contacts.
RE-440-2 comes mounted on a cover which fits an industry standard 2"
x 4" junction box. In this way, for applications which require a
relay at the equipment, a standard "handybox" can be used for the
conduit connection and the RE-440-2 can function as a cover. This
feature significantly reduces the installation time and cost. The
unit has a window for the LED indicator and once installed, the
indicator may be viewed from the outside to verify the status of the
Relay.
For applications which require three relays at a remote location, an
example being a small packaged air handler, the RE-440-3 has three
independent relays mounted on a cover which fits a 4" x 4" junction
box. This allows all three control points to be interfaced to the
controller with minimum installation labour. RE-440-3 also has all
three indicators visible from the outside to verify the status.
With a universal 24 VAC or 24 VDC input, SPDT contact arrangement,
LED indication, extremely small size, terminal strips, and three
packaging options, the RE-440 is the most economical and versatile
pilot duty relay available to interface digital outputs to loads.
