t
The RPS-409A-2P analog ultrasonic sensor is a self contained sensor in a PVC housing
with 2" NPT mounting threads. It is powered
by 20 - 30VDC with reverse polarity protection.
t
The RPS-409A-2P has a short circuit protected analog current sourcing 20 - 4mA output
or an analog voltage 0 - 10VDC output. The
analog current/voltage is a fixed mA/volts per
inch based on the maximum range of the sensor.
t
Example 1: Using the RPS-409A-40-2PA
the output is a linear 0.432mA per inch. A target
placed 3 inches from the sensor will result in an
output signal of 20mA and a target placed 40
inches from the sensor will result in an output
signal of 4mA.
t
Example 2: Using the RPS-409A-40-2PV,
the output is a linear 0.250V per inch. A target
placed 3 inches from the sensor will result in an
output signal of 0.750V and a target placed 40
4mA @ 40"
10.0V @ 40"

0.00V @ 0"

20mA @ 3"
0.75V @ 3"

inches from the sensor will result in an output
of 10V.
t
The RPS-409A-2P has temperature compensation built in to provide accurate readings
throughout the entire operating temperature
range.
t
The sensor is completely sealed and the
connection is made by way of IP and NEMA
rated cables.
t
In addition to the power and analog output
lines there is also a Sync/Tx line. This can be
used for connecting multiple sensors together to
prevent cross talk (Sync), or to force the sensor
to transmit at a particular time/interval (Tx).
t
The RPS-409A-2P is designed to take
advantage of today's PLC and computer analog input cards. The analog card chosen will
determine the resolution of the system. The
numerical values that are programmed into the
PLC or computer will determine the zero and
span.
t
If a set point or set points are required in the
application, please refer to Migatron's SPC-701,
SPC-704, or M-1000 control products. Both the
SPC-704 and M-1000 can also provide excitation power to drive the sensor.
