R81CAA, R81DAA Type
Digital Interface Plug-in Circuit Board Kit
For Series M100 Motor Actuators
Application
R81 digital interface plug-in circuit
board kits are used in Series
M100X base motor actuators, and
as replacement or conversion
board kits in existing Series M100
motor actuators. The R81CAA
and R81DAA kits consist of a
vertical plug-in board, a terminal board with travel and set point
adjustment, top cover with a circuit
board and ribbon attachment,
mounting screws and an
identification label.
The R81CAA (direct acting) and
R81DAA (reverse acting) receive
and interpret commands from the
C500 controller to accurately
position their output shafts. The
R81CAA provides CW action of
the motor actuator on an increase
in command from the C500. The
R81DAA will provide a CCW
action on an increase in the C500
command. These circuit board
kits have return communication,
sending position response
messages back to the controller.
All Series R81C/D electronic
board kits are designed for use
only as operating controls. Where
an operating control failure would
result in personal injury and/or loss of property, it is the
responsibility of the installer to add
devices (safety, limit controls) or
systems (alarm, supervisory
systems) that protect against, or
warn of, control failure.
