Relay 003 - 24 V (ac) Coil
Installation & Operation Manual
Introduction
The tekmar Relay 003 - 24 V (ac) is for use
in applications where device operation
requires a voltage that differs from the
control’s built-in inputs or outputs. They
can also be used in applications where the
device operation requires a higher current
than the on board relay is rated for.
Relay 003 is energized with 24 V (ac)•

Installation
The Relay base can be mounted directly to a flat surface, or onto a standard
TS35 DIN rail. Follow local codes for installation of the relay and wiring. For
class 2 circuits, no enclosure is required. For all other circuits, the relay should
be mounted in an approved enclosure.
Wiring connections are made at the base terminals and are checked with the
relay unplugged.
Relay pulls straight out of base. Base can
be pre-wired and wiring can be tested
Removable
before plugging in relay. Relay can be
replaced without disturbing the wiring.
Wiring
When 24 V (ac) is applied to the relay coil (terminals 2 and 7), the N.O. (Normally
Open) contacts will close and at the same time the N.C. (Normally Closed) contacts
will open. Also, the red LED indicator light on the top of the relay will turn on.
