Thing

UID:
  • tinkerforge:brickletindustrialdual020mav2:[UID]
Required firmware version:
  • 2.0.0
Firmware update supported:
  • yes
Channels:
Actions:
Parameters:
  • Sample Rate – Type: Choice, Default: 4 SPS
  • The sample rate to either 240, 60, 15 or 4 samples per second. The resolution for the rates is 12, 14, 16 and 18 bit respectively.
  • Options: 240 SPS, 60 SPS, 15 SPS, 4 SPS

  • Gain – Type: Choice, Default: 1x
  • The gain between 1x and 8x. If you want to measure a very small current, you can increase the gain to get some more resolution. Example: If you measure 0.5mA with a gain of 8x the return value will be 4mA.
  • Options: 1x, 2x, 4x, 8x

  • Status LED Config – Type: Choice, Default: Show Status
  • The status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets. You can also turn the LED permanently on/off or show a heartbeat. If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.
  • Options: Off, On, Show Heartbeat, Show Status

Channels

Current Sensor 0

The measured current between 0 and 0.022505322A (22.5mA)

Type:
  • Number:ElectricCurrent
UID:
  • tinkerforge:brickletindustrialdual020mav2:[UID]:BrickletIndustrialDual020mAV2CurrentSensor0
Read only:
  • Yes
Unit:
  • Ampere
Range:
  • 0 Ampere to 0.022505322 Ampere (Step 1e-09 Ampere)
Parameters:
  • Update Interval – Type: integer, Default: 1000, Unit: ms, Min: 0, Max: 4294967295
  • Specifies the update interval in milliseconds. A value of 0 disables automatic updates.

  • LED Configuration – Type: Choice, Default: Show Channel Status
  • Each channel has a corresponding LED. You can turn the LED off, on or show a heartbeat. You can also set the LED to Show Channel Status. In this mode the LED can either be turned on with a pre-defined threshold or the intensity of the LED can change with the measured value.
  • Options: Off, On, Show Heartbeat, Show Channel Status

  • LED Status Mode – Type: Choice, Default: Intensity
  • For each channel you can choose between threshold and intensity mode. In threshold mode you can define a positive or a negative threshold. For a positive threshold set the \"min\" parameter to the threshold value in nA above which the LED should turn on and set the \"max\" parameter to 0. Example: If you set a positive threshold of 10mA, the LED will turn on as soon as the current exceeds 10mA and turn off again if it goes below 10mA. For a negative threshold set the \"max\" parameter to the threshold value in nA below which the LED should turn on and set the \"min\" parameter to 0. Example: If you set a negative threshold of 10mA, the LED will turn on as soon as the current goes below 10mA and the LED will turn off when the current exceeds 10mA. In intensity mode you can define a range in nA that is used to scale the brightness of the LED. Example with min=4mA and max=20mA: The LED is off at 4mA and below, on at 20mA and above and the brightness is linearly scaled between the values 4mA and 20mA. If the min value is greater than the max value, the LED brightness is scaled the other way around.
  • Options: Threshold, Intensity

  • LED Status Maximum – Type: integer, Default: 0, Unit: V, Min: -35, Max: 35
  • See LED Status Mode for further explaination.

  • LED Status Maximum – Type: integer, Default: 10, Unit: V, Min: -35, Max: 35

Actions

Actions can be used in rules by creating an action object. All actions return a Map<String, Object>. Returned values can be accessed by name, sometimes the type deduction needs some hints, as shown below:

val actions = getActions("tinkerforge", "tinkerforge:brickletindustrialdual020mav2:[UID]")
val hwVersion = actions.brickletIndustrialDual020mAV2GetIdentity().get("hardwareVersion") as short[]
logInfo("Example", "Hardware version: " + hwVersion.get(0) + "." + hwVersion.get(1) + "." + hwVersion.get(2))

Basic Actions

brickletIndustrialDual020mAV2GetCurrent(int channel)
Parameters:
  • channel – Type: int, Range: [0 to 1]
Return Map:
  • current – Type: int, Unit: 1 nA, Range: [0 to 22505322]

Returns the current of the specified channel.

It is possible to detect if an IEC 60381-1 compatible sensor is connected and if it works probably.

If the returned current is below 4mA, there is likely no sensor connected or the connected sensor is defective. If the returned current is over 20mA, there might be a short circuit or the sensor is defective.

If you want to get the value periodically, it is recommended to use the Current Sensor 0 channel. You can set the channel configuration with the configuration of Current Sensor 0.

Parameters:
  • channel – Type: int, Range: [0 to 1]
Return Map:
  • config – Type: int, Range: See constants, Default: 3

Returns the channel LED configuration as set by the configuration of Current Sensor 0
