R81QAA Type Plug-In Electronic Circuit Board Kit For M100 Series Motor Actuators

Application
The R81QAA plug-in electronic board kit can be used in the M100X base model motor actuator, and as a replacement or conversion kit in existing M100 Series motor actuators. The kit permits the use of A91 and T91 thermistor sensors with the M100 Series motor actuators in heating, ventilating, air conditioning, and industrial applications. The R81QAA has an adjustable set point range of 40 to 90°F (5 to 30°C), with an adjustable proportional band of 2 to 30F° (1.1 to 16.7C°) minimum. The kit consists of mounting screws, an identification label, a vertical plug-in board, and a terminal board with: travel adjustment potentiometer, set point adjustment, proportional band adjustment, labeled wiring terminals. A jumper is factory installed between terminals X and XD for direct output. For reverse output, remove the jumper from the XD terminal and connect the jumper to the XR terminal. When the R81QAA is installed in an M100 Series motor actuator, the voltage between terminal T and terminal X (jumpered from XD or XR) is approximately 6 VDC at zero rotation of the output shaft. Full rotation of the output shaft occurs when the voltage between T1 and X is approximately 10 VDC. With the R81 electronics installed, M100 Series motor actuators will position dampers, valves, and related equipment in heating, ventilating, air conditioning, and industrial applications. All Series R81 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) that protect against, or systems (alarm, supervisory systems) that warn of control failure.
