Potentiometer, joystick and resistance converters

Turns a potentiometer, a joystick with centre position or a resistance sensor into a 4-20 mA, 0-10 V or 0-5 V signal, with adjustable limits. The PR100 series is set up with push buttons, the PR181 series via a display.

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.

PR181 series: signal conditioners with display

The modules in the PR181 series are set up on the display on the module, using the UP, DOWN and OK buttons. On most versions the lower and upper limits of input and output are set independently, as is the rise and fall rate of the output; the settings of each module are listed on the product page under Setup. With an adjustable rise and fall rate, motors, pumps, valves and hydraulics can be driven smoothly. On versions with an analogue output, that output is galvanically isolated from input and supply to prevent ground loops. New settings are stored through the SAVE menu. The standard DIN rail enclosure measures 45 x 83 mm (board 42.6 x 72 mm); versions with more terminals are wider. Most modules run on 9 to 30 V DC at -25 to 55 °C, non-condensing.

For some conversions there is also a version without display and without galvanic isolation in the PR100 series: it is set up with push buttons and runs on 12 and 24 V DC (operating range 11 to 30 V DC). Where one exists, it is listed on the product page under Other version.
