Siemens SIMATIC ET 200SP BaseUnits & Potential Distributors (PotDis)

Siemens SIMATIC ET 200SP BaseUnits & Potential Distributors (PotDis)

BaseUnits form the wiring level of the ET 200SP system: I/O modules plug onto them, and PotDis modules add extra potential terminals.

Key features

  • Push-in terminals; I/O modules plug in without tools
  • Light BaseUnits start a new potential group (max. 10 A), dark ones continue it
  • BU types A0, A1 (with temperature detection), B0, B1, C0 and U0
  • Many versions also in packs of 10 units
  • PotDis BU/TB for additional P1, P2 or bridged terminals
