How to "Slow down" or Ramp your Analog Signal

Need to slow your Analog Signal Output in response to a signal change?

Here's How!...AFP (Analog to Floating Point) plus AUD (Floating Point to Analog Output).

AFP and AUD

AFP converts an analog signal to a floating point signal, and allows you the option of selecting 30, 60, 90, or 120* seconds (full range) as the ramping rate of the output.

AUD converts the floating point signal to analog and allows you to match the 30, 60, 90, or 120* second output of the AFP. The signal is now back to "analog", with the additional feature of slowing the output rate of the signal.

How to Isolate, Re-scale and Limit the Signal

The AIM2 can provide optical signal isolation. The output of the AIM2 can be adjusted to LIMIT THE SIGNAL. The output of the AIM2 can be RE-SCALED.

Used commonly for signal connection to variable speed drive controllers or chiller control packages, the AIM2 is versatile. Some of the features are:

  1.  Solves ground loop problems.
  2. Isolates signal to grounded electric actuators.
  3.  600 VAC optical isolation and 1500 VDC optical isolation.
  4. Output range is field adjustable and limited to the highest adjusted value.
  5. Input and output are selectable for voltage or current.
  6. LED's indicate that incoming and outgoing power supply is present.
  7. Field choice of direct or reverse acting. 
Product Type Features
AIM2 Optical isolation of an analog signal including re-scaling and limiting  All standard industry input and output signals are easily set using dip switches and jumper shunts, plus adjustable settings are available if needed. Output signal will not exceed range set. Easy-to-wire 45o terminals. Capable of adjustment for signal ranges such as 6-9 VDC, 1-17 VDC, and 0-1 mA. 

 

Snaptrack provided has factory drilled holes allowing DIN rail mounting clips to snap into the back of the snaptrack. 

For DIN rail mounting order the "DRC Kit".

What is Pulse Width Modulation?

Pulse Width Modulation Explained

  1. One Shot and Looped Pulses: Enter pulse ranges from .01 to 999.99 (Seconds, Minutes or Hours).
  2. Duty Cycle Pulse (Period time): Valid values can range from .01 to 650 in Seconds only.
  3. Duty Cycle Pulse: Values are entered in percent ranging from 0 to 100% in 1% increments. This percentage value is the percent of the Period time that the pulse will be turned on.

Pulse Width Modulation Explained

The following products accept Pulse Width Modulated signals and output various types of analog or pressure signals (see specifications on each product for details).

PTA - Outputs analog signal

DRN3.1 - Outputs range of resistance signals

PTA2 - Outputs analog signal

DRN4 - Outputs 0-135 ohm resistance signal

DMUX - Relay output

Save Controller Inputs by Averaging Zone Temperatures

DID YOU KNOW?

Multiply Temperature Sensors can be wired to provide one average output signal.

Instead of using separate inputs for two, three or four rooms, average those temperatures and run one signal back to a single input on your BMS controller.

There are two methods used to provide an average output from your sensors. The method you use will depend on the type of sensors, resistive or analog, in your application. Watch as ACI’s Tech Support Manager, Matt Buchholz, demonstrates the wiring of both methods in ACI's Tech Tips Video #3, Saving Controller Inputs by Averaging Room or Zone Temperatures.
