PRODUCT OVERVIEW
The Speed Relay is a microprocessor controlled digital speed monitor for use with 2,
3, or 4 wire NPN/PNP sensors or Contact sensor inputs, with a user programable
electromechanical relay and PhotoMOS Solid State Relay (SSR) outputs. The Speed
Relay has a 160x80 pixel LCD display to provide information, and 3 front panel buttons
to program settings.
The Speed Relay reads input pulses and displays the calculated pulse frequency in a
range of selectable units.
The user can set the Electromechanical Relay and PhotoMOS Solid State Relay
outputs independently, with their own thresholds and output behaviors, and have the
Alarm LED indicate the state of one of the outputs. The Electromechanical Relay can
be set to trigger when the input speed is outside the chosen range. The PhotoMOS
Solid State Relay can provide a trigger output or can be configured to provide a pulsed
output that matches the input pulse frequency.
One LED (Input LED) shows input status of the sensor’s pulses, and another LED
(Alarm LED) shows the state of the assigned output.

USR1V46 Powered by AC
Speed Relay Powered by DC
The USR1V46 Speed Relay can be powered from an AC source or a DC source. If the
Speed Relay is powered via AC using terminals 7,8, and 9, then the Speed Relay
provides a +24 VDC supply from pin 1 to power a sensor which is rated for 100 mA.
A 2 wire NPN sensor can be powered from Terminal 4 which is rated for 24 VDC, 50
mA.
If the Speed Relay is powered via DC using terminals 1 and 2, then the sensor should
be powered from the same supply.
Ensure all connections are correct before applying power.
The speed relay can only operate with a single sensor at a time, do NOT attach more
than one sensor simultaneously.

Interlock Wiring
When the interlock setting is set to “USED” the Interlock must be connected for
outputs to trigger. When the Interlock is connected and the start-up delay has elapsed,
the symbol RUN is displayed at the top of the runtime screen.
When the interlock setting is set to “NOT USED” the state of the interlock does not
matter.
INSTALLATION
The Speed Relay should be wired as show in the connection diagrams in Electrical
Setup.
Speed Relay Mounted on 35mm DIN rail
The Speed Relay should be mounted on a 35mm DIN rail in suitable enclosure of
protection rating IP40 or above. The enclosure door should be kept locked when the
system is in operation.
Use a small flathead screwdriver to lower the hook on the rear of the Speed Relay to
install or remove the device.
