The RPS-409A-IS2 is an intrinsically safe
analog ultrasonic sensor available in a variety of
ranges. The RPS-409A-IS2 sensors can be used
in hazardous gas or dust environments classified
as Zone 0, 1, 2, 20, 21, or 22 for ATEX/IECEx,
and Class I, II, or III for UL/cUL when used
with approved intrinsic safety barrier(s). See
the RPS-409A-IS2 User Manual and Control
Drawing No. Ex05021114 for further information on installation in hazardous locations.t
t
The sensor is self-contained in a 30mm
barrel style enclosure, and is powered by 16 - 30
V dc with reverse polarity protection.
t
The RPS-409A-IS2 has a short circuit
protected 0 - 10 V dc analog output. The analog voltage is a fixed volts per inch based on
0.00V @ 0"t

10.0V @ 80"

1.25V @ 10"

the maximum range of the unit. For example
when using the RPS-409A-80-IS2, the output
is a linear 0.125 V per inch. A target placed 10
inches from the sensor will result in an output
of 1.25 V or a target placed at 80 inches from
the sensor will result in an output of 10 V.
t
The RPS-409A-IS2 has built-in temperature compensation to provide accurate readings
throughout the entire operating temperature
range.
t
An LED indicator is provided. The
LED is green with no target detected and
changes to red when a target is detected.
t
t
The sensor is completely sealed and connection must be made with a cable having a
rating of IP67 or greater.
t
In addition to the analog output line the
sensor also has a Sync/Tx line. This line can
be used for connecting multiple sensors together
(Sync) to prevent cross talk, or to control when
the sensor transmits (Tx).
t
The RPS-409A-IS2 is designed to take
advantage of today's PLC and computer analog input cards. The numerical values that are
programmed into the PLC or computer will
determine the zero and span of the sensor.
