Small Electronic Controller

The RPS-302 has 2 sealed, multiplexed
transducers with independent range control
adjustments, LED indicators, and form C relay
outputs. This sensor also has a unique master and slave feature which enables many of
the same units to be used within close proximity of one another without cross-talk interference. For example, if three sensors are
needed in a close area, one sensor would be
left as a master and the other two would be
slaves. This is done by means of the X IN,
X OUT, and GND connection on the board.
One sensor (master) would send a signal by
means of the X OUT and GND terminals.

Proximity Detection

Proximity Detection
Proximity detection is the detection of an object in a given
range. The detection range of the RPS-302 is controlled by
the "Range Control" potentiometers located on the front
cover of the controller. Any object within the desired range
is detected, while objects out of range are ignored. The
detect point is independent of size, material, and reflectivity.

These would be connected to the X IN and
GND terminals of the other two sensors
(slaves). With the sensors connected in this
way, all units would be transmitting and receiving at the same time. This then would
prevent cross-talk and enable all three sensors, or all six transducers, to be used at the
same time in close proximity of one another.
There are also separate turn ON and turn
OFF DELAY potentiometers provided for each
transducer. All four DELAY controls are located along side the black module inside the
enclosure box. The remote transducers allow
for mounting of the sensor heads in cramped
spaces while the controller is out of the way.
The (2) independent and isolated form C
relays furnish N.O. and N.C. outputs. This
sensor, operates at a frequency of 222kHz
for the 14" and 36" ranges and 150kHz for
the 72" range. This sensor has a narrow sensing
beam. Sensing ranges available for the RPS302 include 4" to 14", 5" to 36" and 8" to
72". Mounting flanges, LED indicators, ranging potentiometers, and 6-ft. transducer cables
are included. Optional cable lengths are available.
