Software with RS-232 converter for configuring DRPA proportional regulators
Code: DRPAANALYSE
Related products
Product detailed description
The DRPA ANALYSE software with RS-232 converter connects the AirCom DRPA proportional pressure regulator to a computer. It shows the setpoint and actual pressure, records the control behaviour and lets you adjust the regulator settings. It is useful when commissioning a machine, when tuning fast or very stable control and when troubleshooting.
What the software does
- display of the setpoint pressure, actual pressure and control parameters
- recording of the control behaviour – you can see straight away how quickly and how smoothly the pressure settles
- setting of the zero point, range, limits and ramp
- selection of P, PI or PID control and its parameters
- diagnostics and maintenance of the regulator
- saving the settings and using them for other regulators
The software is not needed for normal operation of the DRPA regulator – the regulator is factory-set.

AirCom Pneumatic GmbH from Ratingen, Germany, is a specialist in pressure and flow control of gases and liquids. Its range includes pressure regulators from miniature to high-pressure, precision and proportional regulators, compressed air treatment, pressure switches and pressure transmitters.
From AirCom we offer RPM low-pressure regulators, which hold a constant pressure from 5 to 1500 mbar, and DRPA proportional pressure regulators, which set a pressure of 0 to 16 bar according to an electric signal of 0–10 V or 4–20 mA. Plus a mounting bracket for the RPM 12 and software for setting up the DRPA.

How to choose and connect an AirCom regulator
1. Manual or electric setting
An RPM regulator holds a constant low pressure that you set once by hand. If the machine control system is to change the pressure, choose a DRPA proportional regulator.
2. Range and size
Choose the smallest range that your pressure fits into – the setting will be finer. Choose the size by the flow in the table above. Mind the units: 1 bar = 1,000 mbar.
3. Prepare the air
Install a compressed air filter upstream of the regulator. The DRPA works with lubricated and non-lubricated air filtered to 50 µm; keep the inlet pressure at least 10 % above the highest pressure to be set.
4. Connect and set
Connect the regulator according to the arrow on the body. On the RPM always set the pressure upwards and lock it with the lock nut. Connect the DRPA via the M12 connector to the 24 V DC supply and the control signal.
Frequently asked questions
- What is the difference between RPM and DRPA?
- The RPM holds a constant low pressure from 5 to 1500 mbar that you set by hand. The DRPA sets a pressure of 0 to 16 bar according to an electric signal from the control system and constantly monitors the outlet pressure with a sensor.
- Does the RPM regulator come with a pressure gauge?
- Yes, a ⌀ 63 mm pressure gauge with a scale matching the range is included. It screws into one of the two G 1/4" side ports.
- Do I need software for the DRPA?
- No, the regulator is factory-set. The software with RS-232 converter is useful if you want to change the zero point, range, ramp or control parameters, monitor the pressure curve or troubleshoot.
- What does the DRPA do if the signal or supply fails?
- It exhausts the outlet. It fills and exhausts the outlet with the same flow and consumes no air itself.
- What does the manufacturer call these regulators?
- The RPM 12 corresponds to type AirCom R161-04, the RPM 10 to type R160-08 and the DRPA to the PP series (proportional regulators with digital control). The full RPM type designation is on each regulator’s product page.
- Where can I find all regulators?
- RPM regulators are in the category RPM low-pressure regulators, DRPA in the category proportional pressure regulators – together with other proportional regulators.
