Position switch module

 
 
U-ONE Generation II (LWL) - position switch modulezoom

Short info: Universal encoder systems

  • Monitor position ranges by means of 3 configurable position switches equipped with positively driven relays
  • Easy configuration instead of complicated PLC programming
  • Switching capacity up to 250 VAC / 500 mA or 230 VDC / 180 mA
  • Options: Without SIL/PL certification (UO-ERC-R); combine up to 15 position switches (= 5 modules)

U-ONE Generation II (LWL) - position switch module

The position switch modules of the U-ONE(-SAFETY) second generation monitor the position ranges via three position switches, each with configurable parameters. The combination of five modules allows a maximum of 15 position switches to be used. The switching range, hysteresis and preset values can all be programmed. What’s more, the modules can also be parameterized as reliable error switches and for a switch test diagnosis. The parameterization is carried out using input masks, meaning that complex SPS programming is not necessary. The modules are optionally available as certified up to SIL 2 / PL d.
