The PR’s has relais outputs, Relay outputs use an electromagnetic coil to actuate a switching contact. When the control voltage is applied to the relay coil, it either closes or opens the switching contacts to control the load.
Whereas PNP tra...

Yes, the PR-devices series can be used to monitor and control the consumption of a PV system. The PR series supports the Modbus RTU protocol, making it compatible with any energy meter that supports this protocol. The digital outputs of the series ar...

The user program is written to the retain memory. The battery can be changed without any issues, and the program remains unaffected. It's worth noting that when the battery is replaced, the RTC will be reset. The battery typically lasts for about 8 y...

Any HMI device compatible with the Modbus RTU Protocol is of displaying process values and can be utilized as an HMI with the PR device series.

The program is stored in the retain memory, which remains unaffected in the event of a power failure. Therefore, in the event of a power failure, your PR device will retain the program and will not require reprogramming. Variables that must be stored...

Yes the PR-devices can function as PID-Controller, our ALP Software utilizes function block language and comes with preinstalled macros like PID Controller and PWM Generator, among others.

Yes, the PR-Devices can be used to control pumping systems. Therefore, we recommend exploring the sample projects available on our website. We also offer sample projects that showcase the capabilities of PR devices, such as a press machine.
In one ...

If the accuracy of the input or output of the module is no longer in accordance with the specification, it can be calibrated.
Each analog input and output has its own calibration coefficients for each sensor type.
– The calibration is perform...

Modbus registers work as a way to store and exchange data in Modbus communication, which is a popular protocol used in industrial automation and control systems. Modbus registers are typically 16-bit values, and they are indeed represented in hexadec...
