PR100 module in DIN rail holder, front three-quarter view

4-20 mA to 0-10 V converter, push-button setup

Article number PR100s06

The PR100s06 converts a 4-20 mA current loop into a 0-10 V DC voltage signal. The output is calibrated with the push buttons: input at 20 mA, press the button for 10 V; input at 4 mA, press the button for 0 V. Fine adjustment by hand remains possible afterwards. The output is not galvanically isolated: the output minus is internally connected to the supply minus.

Supply 12 and 24 V DC, operating range 11 to 30 V DC
Input 4-20 mA current loop
Output 0-10 V DC

Other version: PR181-X003. The PR181-X003 converts two 4-20 mA or 0-20 mA signals into two 0-10 V outputs, galvanically isolated from inputs and supply. It is set up on a display, and the rise and fall rate of the outputs is adjustable as well. Supply 9 to 30 V DC, ambient temperature -25 to 55 °C, non-condensing. Do input and output need to be isolated, or would you rather set it up on a display? Then choose the PR181. Otherwise the PR100 is sufficient.

Setup

Set up the module when it is first connected and every time you use a different 4-20 mA input.
Connect the current loop to terminals 6 (plus) and 7 (minus), and the output to terminals 3 and 4.
Apply 12 or 24 V DC to terminals 1 and 2. The green LED lights continuously.
Hold button 3 for four seconds. The LED flashes green: the module is in programming mode.
Set the current source to 20 mA, the maximum, for an output of 10 V. Hold button 2 for four seconds. The LED flashes quickly for two seconds.
Set the current source to 4 mA, the minimum, for an output of 0 V. Hold button 1 for four seconds. The LED flashes quickly for two seconds.
Hold button 3 again for four seconds to save. The LED flashes quickly for two seconds and then lights green continuously. The module is ready for use.
To restore the factory settings: disconnect the supply, hold button 2 and reconnect the supply. If the green LED flashes briefly and quickly, the module has been reset.

PR100 series: converters with push-button setup

The converters in the PR100 series are set up with three push buttons and a green LED on the module. Button 3 puts the module in programming mode, button 2 stores the value for the maximum and button 1 the value for the minimum; button 3 saves. The output can then still be fine-tuned by hand. All versions run on 12 and 24 V DC, operating range 11 to 30 V DC, at an ambient temperature of 0 to 55 °C; the board measures 43 x 72 mm and a DIN rail holder is supplied as standard. The output minus is internally connected to the supply minus: the PR100 is not galvanically isolated. To restore the factory settings, disconnect the supply, hold button 2 and reconnect the supply.

Do input and output need to be isolated, or would you rather set it up on a display? Then choose a module from the PR181 series: it is set up on a display, runs on 9 to 30 V DC and has a galvanically isolated output and an adjustable rise and fall rate. Where a PR181 exists for the same conversion, it is listed on the product page under Other version.
