The versatile RELAY-URM Series
relay module can switch up to eight
15 A loads using low-level input
signals from PLCs, process
controllers, and indicators. Its
flexible inputs will accept a wide
variety of control signals. Selectable
input allows activation of output
relays on a direct-acting or reverseacting signal. Similarly, input signals
can range from 5 to 24 Vdc.
Conditioning of input allows
open-collector or logic level inputs
(e.g., TTL, CMOS) from PLCs or
controllers to be used for switching
output relays. In addition to working
with control/logic level signals, the
RELAY-URM-800,
$195, shown close to actual size.
RELAY-URM can activate output
relays on contact closure.
Many process-control instruments
have low-power relays that provide
contact closure for low-amperage
switching but are not suitable for
handling heavy loads. Simply
connect the low-power relay contact
output to the RELAY-URM unit and
instantly get up to eight 15 A load
switching relays.
Input and output connections are
made through Euro-style pluggable
connectors, conveniently located on
the top and bottom of the unit.
Screw-in terminals allow for quick
P-117
connect/disconnect of wires.
The unit is housed in a versatile
enclosure that can be mounted on a
DIN rail or a wall. If desired, the
same enclosure can be panel
mounted, with relay and AC and DC
supply status visible on the front.
LEDs on the front panel turn on
when a relay is energized.
Both 4- and 8-relay module units
come with a built-in universal
power supply that operates on
100 to 240 Vac. This supply provides
power to the internal electronics and
relays and puts out up to 20 W
(5, 12, or 24 Vdc), available for
external applications.
