Tension Electronics
PFEA 111, 112, 122 and 113
Overview
Covering a wide range of applications the Tension Electronics comes in four versions, with different levels of performance and functionality. All four versions have multi-language digital display and configuration keys. The configuration keys being used for setting different parameters and to check the status of the tension system.
The 2 x 16 character display can present sum, difference or individual load cell signals.
All four versions are available in both DIN-rail.
Features and benefits
Interactive menu
<p>The tension electronics has a unique interactive menu which guides the commissioning step by step, eliminating the potential for making mistakes and significantly reducing startup time.</p>Built-in self diagnostics
<p>The electronics continuously supervise a number of important parameters and provides error messages if something goes wrong.</p>Multi-language display
<p>The multi-language display is a great feature that helps to eliminate mistakes, during start-up and/or operation of the tension system.</p>Load memory
<p>The resettable load memory stores max. load values. A useful tool for maintenance.</p>Analog outputs
<p>The PFEA provide a scaled and zeroed tension output ready for use in control or monitoring. Individual scaling and filtering can be done for each of the analog outputs.</p>PROFIBUS-DP, PROFINET and EtherNet/IP
<p>PFEA112 and PFEA113 have Fieldbus communication via PROFIBUS DP as standard. PFEA122 comes with PROFINET RT and EtherNet/IP communication.</p>Product Data PFEA11x
