Universal

The PReasy 4000 series is the latest example of reliable modules from PR electronics. The PReasy modules are designed to achieve the optimally efficient process, and we have focused on the following 3 characteristics in order to meet user needs:

• Universal – User-friendly – Reliable

Universal

In all aspects of the design PR electronics has focused on the universality of the new 4000 series. Hence, the 4 product variants cover hundreds of applications, resulting in reduced stock as well as increased flexibility and competitiveness: 

• Universal supply voltage of 21.6..253 VAC / 19.2..300 VDC.

• Universal input module for the connection of mA, V, Pt100, TC, lin. R and potentiometer.

• Universal programming by way of the display front 4501, which recognizes the module type in question and adapts the menu structure accordingly.

User-friendly

The communication between user and module is characterized by its simplicity and thus the configuration can be carried out without a detailed manual. The following features optimize the usability of the PReasy 4000 series:

• The menu is easily understandable as the scrolling help text guides the user through all the configuration steps.

• All configuration options can be selected from the display front without the need of a PC, DIP-switches, jumpers or special tools.

Reliable

Product reliability has always been one of the key words at PR electronics. Securing customer processes also includes the elimination of potential risks in connection with e.g. mounting errors or general mishandling, which may occur in stressful situations. In addition to our usual 5-year product guarantee, the PReasy 4000 series integrates the following protection features:

• 2.3 kVAC galvanic isolation between input, supply, relays and analog output.

• Sophisticated sensor error detection with alarm function by way of the relays or the analog output.

• Process simulation by way of the relays or the analog output.

• 4114 and 4116 are suitable for SIL 2 applications.

• FM-approved for installation in Div. 2.

• The 4000 modules comply with UL 508, NAMUR 21 (burst), NE43 (sensor error) and LVD.

Easy configuration

The 4000 series can be delivered pre-configured from factory, but the display front provides access to advanced configuration directly in the process. Besides standard configuration of input, output and relays, the display front provides access to several other functionalities such as display configuration, process calibration, simulation mode function and much more.
