PR515 module in horizontal DIN rail enclosure, front three-quarter view, with screw terminals and USB-C port

Frequency or pulses to 0-10 V and 4-20 mA, with OLED display

Article number PR515x555

The PR515x555 measures the frequency of a pulse signal on an isolated input and passes it on as 0-10 V and as 4-20 mA. This turns an inductive sensor, a gear pick-up or a flow meter with pulse output into an analogue signal for a PLC or meter. Which frequency corresponds to the start and the end of the output, and the number of pulses per revolution, are set on the OLED display. A version for an input at mains voltage is available on request.

Supply 12 and 24 V DC, operating range 11 to 30 V DC
Input pulse signal or frequency, for example from an inductive sensor or flow meter; galvanically isolated
Output 0-10 V and 4-20 mA (active), simultaneously

Setup

Connect the supply, the pulse source and the outputs according to the wiring diagram supplied with the module.
On the display, set the number of pulses per revolution, or select display in hertz.
Set the frequency or speed at the start and the end of the output and store with SAVE.

Application

Passing on the speed of a shaft, engine or pump as 0-10 V or 4-20 mA
Connecting a flow meter with pulse output to a PLC with an analogue input
Converting a frequency for an analogue meter on a panel

PR515 series: controllers and converters with OLED display

The modules in the PR515 series have an OLED display and push buttons, so they can be set up without a computer and show the current values of inputs and outputs. They run on 12 and 24 V DC systems. Most versions can be extended on request, for example with an extra relay output, a PWM output, a bus connection (CAN bus or Modbus) or a different sensor input.
