Universal Series timers

TR timing relays

Eaton’s Universal TR Series timers are a versatile and
cost-competitive family of timing relays. The compact
IEC-style housing installs easily onto a standard DIN rail,
and the direct-wire design eliminates the need for
additional sockets and accessories. Each timer has multiple
user-selectable timing functions and timing ranges, and a
universal input voltage of either 12 or 24 volts to 240 volts
AC or DC, depending on the model.

Reducing your inventory costs

With up to seven selectable
timing functions and seven
selectable time ranges from
50 milliseconds to 100 hours,
you can meet the needs of
almost any application with
just one or two stock items.
Do you need 24 Vdc control in
some cases and 120 V
in others? You are covered with
the Universal TR Series timer, as
it has a universal, self-selecting
control voltage input range from
either 12 or 24 volts (depending
on model) to 240 volts AC or
DC. Are you tired of buying
minimum quantities of sockets
and accessories for your plug-in
timing relays? The direct wire
design of the Universal TR
Series gives you everything
youneed in a single item.

Reducing your labor costs

During initial installation, the
large terminals on the Universal
TR Series make wiring quick
and easy
even allows easy access to the
bottom terminals when the top
wires are installed. The easy-to­read set point markings improve
the accuracy of setup, thereby
reducing your startup time. Are
you spending too much time
troubleshooting and replacing
timers? The dual LED indicators
on the Universal TR Series use
multiple modes to signal input
power, relay state and timing
status. The Universal TR Series
also features a high-quality
design with twice the relay life
of many competitors.
