R7195A,B

Motor Positioner

APPLICATION

The R7195A,B Motor Positioner is a single channel solid state 

proportioning amplifier that will accept an output signal from a 

controller to position a reversing control motor with a 135-ohm 

or 1000-ohm feedback slidewire. Motors with slidewires that 

have resistances other than 135 ohms or 1000 ohms will be 

shunted to one of these two values. 

The R7195A Motor Positioner is factory-adjusted to accept a 4 

to 20 mA input. The R7195B Motor Positioner is 

factory-adjusted to accept input from a 135-ohm 

retransmitting slidewire.

FEATURES

• Accepts 4-20 mA or 135-ohm signal to provide position 

proportional control of M944 Modutrol® Motor without 

balance relay and M940A,B Actionator.

• Heavy duty case.
• Mounts directly on M940 Actuator.
• Solid state design extends product life and reliability.
• Zero, span and deadband adjustments allow motor to 

be field adjusted to various input ranges: i.e., split 

ranging.

• Hard Manual feature allows operator to override the 

controller (4-20 mA or 135-ohm input) action to open or 

close fully the final control element.

• Reversing direction of motor can be accomplished by 

simple wiring change of R7195.

• Output from one R7355 4-20 mA DialaTrol can operate 

up to eight R7195 Positioners and associated M944 or 

M940 Actuators.

• Output from one 135-ohm Series 90 Controller can 

operate up to five R7195B Motor Positioners.

• Span and zero adjustment do not interact with each 

other so each adjustment can be made independently 

without having to readjust the other parameter.

• Can operate with motor feedback slidewire between 

100 and 1000 ohms.
