Most of the sensors sold at Phidgets are simple 0-5V devices that can be read directly from a VINT port (See the "Compatible Products" tab for a list of VINT Hubs). But sometimes, you need a special sensor, be it a 4-20mA pressure sensor or a frequency output flow meter. The Versatile Input Phidget aims to provide an interface for as many types of sensors as possible while still keeping its compact form and low price point. Listed below are the various options for this adapter:



Power Supply 12V/24V

If you have a sensor that requires more than the typical 5V, this option allows you to generate a 12V or 24V power supply. This power is supplied directly through the VINT port with no need for an external power supply, cutting down on messy power wiring. You can also turn the power off through a command in your program as a power saving and control feature.

Voltage Input 5V

Functional

Similar to a VINT port opened in VoltageInput mode, this input will read in a 0-5V signal from a 5V sensor. This input is included primarily for industrial sensors that require a 12V or 24V supply, but still return a 0-5V signal. This input, however, does not support ratiometric sensors. For sensors that only require 5V power, you can just use a VINT Hub or InterfaceKit.

Current Input 4-20mA

Functional

This input can interface sensors with a 4-20mA output. These sensors are often used in applications with long wires where a voltage signal would normally drop off due to line resistance and be susceptible to interference. You can also use this input to measure small currents in a circuit, but only in the range of 0.5 to 20mA.

FrequencyCounter Input

Functional

Do you have a sensor that outputs a frequency signal, or do you need to count the number of logic-level pulses on a line? With this input, you can count pulses and measure the frequency being output by your sensor up to a maximum 1 MHz. You can also select a cutoff frequency in software to determine when a frequency is considered to be 'zero'.

Digital Input PNP/NPN

Functional

For a sensor with a simple output that switches to logic high (PNP), or switches to ground (NPN), this input provides a 10 kΩ internal resistance to pull the line down or up, respectively.

Getting Started

Welcome to the DAQ1400 user guide! In order to get started, make sure you have the following hardware on hand:


Next, you will need to connect the pieces:

DAQ1400 Functional.jpeg
  1. Connect the DAQ1400 to the VINT Hub using the Phidget cable.
  2. Connect the VINT Hub to your computer with a USB cable.
  3. Connect sensor or device to the appropriate input on the DAQ1400. For details, see the technical section.


Now that you have everything together, let's start using the DAQ1400!

Using the DAQ1400

Phidget Control Panel

In order to demonstrate the functionality of the DAQ1400, the Phidget Control Panel running on a Windows machine will be used.


The Phidget Control Panel is available for use on both macOS and Windows machines. If you would like to follow along, first take a look at the getting started guide for your operating system:


Linux users can follow the getting started with Linux guide and continue reading here for more information about the DAQ1400.

First Look

After plugging the DAQ1400 into your computer and opening the Phidget Control Panel, you will see something like this:

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

  • Serial number: allows you to differentiate between similar Phidgets.
  • Channel: allows you to differentiate between similar objects on a Phidget.
  • Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.


The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Technical Details

Interfacing with sensors

The DAQ1400 is capable of interfacing with a wide variety of sensors. This section will help you understand what the DAQ1400 is capable of, and how to use it.

Using the Voltage Input (0-5V)

DAQ1400 VoltageInput Diagram.jpg

This mode measures an input between 0V and 5V. To connect your 0-5V sensor to the DAQ1400, wire the sensor to the terminals as pictured in the diagram. You may need to refer to the datasheet for your sensor to determine which wire is which.

Using the Current Input

DAQ1400 CurrentInput Diagram.jpg

This mode is designed to interface a 4-20mA sensor, which is a common industrial standard. To connect your 4-20mA sensor to the DAQ1400, wire the sensor to the terminals as pictured in the diagram.

Even though this mode is intended for this specific purpose, you can also use it as a general-purpose current sensor, in which case it can measure current values between 0.5mA and 20mA (Measuring below 0.5mA is not recommended).

Using the Digital Input

DAQ1400 DigitalInput Diagram.jpg

Some industrial sensor have a simple true/false value which can be read by a digital input. Many proximity or movement sensors have this kind of output. It is common that these sensors will require a 12V or 24V power supply, so other Digital Input Phidgets are not a complete solution in this case. A digital sensor will either be PNP or NPN:

  • An NPN sensor will switch the sensor line to ground whenever the sensor activates.
  • A PNP sensor will switch the sensor line to power whenever the sensor activates.

Normally, you'd need a different kind of digital input to interface these two types of sensors. Luckily, the DAQ1400 can read either one; all you have to do is set the Input Mode property to the correct type. To connect your digital sensor to the DAQ1400, wire the sensor to the terminals as pictured in the diagram.

Using the Frequency Counter

DAQ1400 FrequencyInput Diagram.jpg

Sensors that measure using rotation such as flow meters or anemometers usually have a pulse output. For example, a flow sensor might send a 5V pulse down the line every time the turbine makes a full rotation. Using this information with timestamps, you can calculate the turbine speed. While you could theoretically use a Phidget with a Digital Input to read this kind of signal, most digital input boards are not designed to read pulse signals that change this frequently, so they'll miss pulses and calculate the wrong speed. The DAQ1400 is specially designed to read these high frequency pulse signals when in Frequency Input mode.

To connect your sensor to the DAQ1400, wire the sensor to the terminals as pictured in the diagram.

Pull-Down Resistor

If your sensor frequency is faster than 600Hz, you may seem to be 'maxing out' the DAQ1400. This is because the pull-down resistance is too weak to pull the signal down. To strengthen the pull-down, put a 10KΩ resistor across the Digital and Gnd terminals.


Current Consumption

Current consumption of the DAQ1400 will vary depending on which mode you're using:

Mode Unconfigured Current Consumption (mA) Configured Current Consumption (mA)
VoltageInput 0.023 8
CurrentInput 0.023 8
DigitalInput 0.022 9.5
FrequencyInput 0.023 9.7

These figures are based on the 12V power supply. Increasing the power supply to 24V adds approximately 0.7mA of current consumption.
