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.
