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.
