Manual Analog Override Switch, Alarm
- Manual override for analog control: The ACI MAO installs between a controller and actuator to provide adjustable manual analog override when needed.
- Supports two independent outputs: Routes two analog signals in normal operation and allows each output to be switched from automatic to manual independently.
- Ideal for actuator troubleshooting: Useful for temporary override during controller issues, actuator checkout, linkage testing, and system commissioning.
- Flexible signal compatibility: Selectable output ranges include 0-5 VDC, 0-10 VDC, 0-15 VDC, and 0-20 mA for common BAS control applications.
- Alarm feedback during override: Provides an alarm contact output to indicate when manual override is active, helping operators identify overridden equipment.
- Adjustable field control: Potentiometers allow technicians to vary each manual output signal directly during setup or service.
- Panel-friendly installation: Compact snap-track mounted board with 45° captive screw terminals supports clean installation in control panels.
- Reliable interface design: Operates on 24 VAC or 24 VDC power and includes RoHS2 and WEEE approvals for building automation projects.
