1. RSD200P PNeUmATIC CONNeCTIONS
Nexen developed the RSD200P for applications that would benefit from tension setpoint compensation. The
RSD200P features an integral pressure sensor that connects to the air supply pressure of the dancer arm loading
cylinder. As the tension setpoint changes via the air pressure of the loading cylinder, the RSD200P measures this
change and adjusts its performance accordingly. The RSD200P pressure sensor’s calibration procedure is explained
in the SENSOR CALIbRATION section.

The RSD200 requires a +24 VDC Power Supply,
Dancer Arm Position Sensor, Current- or Voltage-to-
Pressure Converter, and a dry circuit contact or switch
for any pneumatic brake or clutch applications. (Refer to
Figure 4).
2 VDC Power Supply: Provides the power for
operation (Refer to SPECIFICATIONS for details).
Dancer Arm Position Sensor: Provides an analog
signal that tracks dancer arm movement.
Current- or Voltage-to-Pressure Converter: (ex.
Nexen’s EN50 or EN40) Converts the appropriate
control output (i.e. 4-20 mA or 0-10 VDC) into air
pressure for use with a pneumatic brake or clutch.
Start/Stopped Signal: Lets the RSD200 know when
the web is moving or stopped.

:
The RSD200 requires a +24 VDC Power Supply, Dancer
Arm Position Sensor, optional second power supply,
and a dry circuit contact or switch for a motor drive
applications. (Refer to Figure 4).
2 VDC Power Supply: Provides the power for operation
(Refer SPECIFICATIONS for details).
Dancer Arm Position Sensor: Provides an analog signal
that tracks dancer arm movement.
Optional Power Supply: Used when isolated inputs or
outputs are required. Most commonly used to prevent
the mixing of power supply commons together when
connecting the analog output to a motor drive (Refer to
SPECIFICATIONS for details).
Start/Stopped Signal: Lets the RSD200 know when
the web is moving or stopped.

:
1. Remove power from RSD200.
2. Disconnect the Power and Signal Cable Connectors from the RSD200 base.
3. Move the printed circuit board side-to-side while pulling to remove board.
NOTe: Factory installed fitting
accommodates .2 inch tubing.
A fitting for mm tubing is also
included with the RSD200.
