R81CAA, R81DAA Type Digital Interface Plug-in Circuit Board Kit
For Series M100 Motor Actuators

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.
