Analog, Pulse, or Floating Point to Resistance |
Analog inputs of 0-5, 1-5, 0-10, 2-10, 0-15, 3-15 VDC, 0-20 or 4-20 mA. Floating Point rates of change of 30, 45, 60, 90, 120, and 240 seconds. Pulse inputs of .02-5 sec., .1-25.5 sec., .59 to 2.93 seconds, .1 to 10 seconds, .023 to 6 seconds, and 0-10 second Duty Cycle Pulse (sampled in a 10 second window). On a power failure, fails to original controller, or the value of the resistance connected at the failsafe terminals. |

Two unique uses for the AAR that may solve a problem for you.
Problem: From one analog signal I want to turn ON a load when the analog signal increases to a certain value, and if it continues to increase, OFF again.
Solution:
- Set R1 to turn ON at (?) 6 mA.
- Set R2 to turn OFF at (?) 10 mA
As the signal input to the AAR increases to 6 mA the load will turn ON. As the signal input to the AAR continues to increase to 10 mA, the load will turn OFF.
Problem: From one analog signal I want to turn a motor ON at low speed when the signal increases to a certain value, and to high speed if the signal continues to increase above a certain value.
Solution:
- Set R1 to turn ON at (?) 6 mA.
- Set R2 to turn ON at (?) 10 mA
When relays R1 and R2 are off, High and Low speed are OFF.
When relay R1 is energized, Low speed is ON.
When relays R1 and R2 are ON, High speed is ON, Low speed is OFF.

The MAO (Manual Analog Override) and MDO (Manual Digital Override) allow for manual interruption and simulation of the building automation system’s control signal.
Manual Analog Override
The MAO also makes an innexpensive and effective 2 channel signal generator for start-up or bench testing
The MAO was designed to add 2 channel analog override control similar to an Hand/Off/Auto switch. When the MAO is in Auto mode the control signal is passed directly from the input to the output.
When in Manual mode the MAO can produce a 0-5, 0-10, 0-15 VDC or a 0-20 mA signal. The MAO override output signal is controlled with a single turn potentiometer.
When power is lost or removed the MAO output will default to the original input control signal.
The MAO also provides a single status feedback signal that can be configured with different values of resistors. Each channel can send back a unique resistance which allows for the identification of which channel is in override mode.
The override status can also be configured for N.C. or N.O. operation.
See all MAO products
Manual Digital Override
The MDO was designed to add 4 channel digital override control, similar to a Hand/Off/Auto switch.
When in Auto mode, the MDO will pass a signal of 0-24 VDC or 0-24 VAC from the input to the output.
When the override switch is placed in manual mode, the output is then controlled by an ON/OFF switch. The switch in the on position sends the voltage from the power supply to the output. AC or DC can be used. When power is lost or removed the MDO output will default to the original input control signal.
The MDO has a single channel feedback status that can be configured with different values of resistors for individual channel override identification.
The override status can also be configured for N.C. or N.O. operation.
