With the BaseUnits (BUs), the ET 200SP offers a rugged and service-friendly design with permanent wiring:

  • No tools needed for one-handed wiring using push-in terminals
  • Actuation of the spring NC contacts with a standard screwdriver, with a blade width up to 3.5 mm
  • Outstanding access due to arrangement of measuring tap, spring NC contacts and cable entry in columns, while at the same time reducing the space required by 64%
  • Fault-proof color coding of the spring NC contacts for better orientation in the terminal panel
  • Replacement of I/O modules during operation without affecting the wiring
  • Operation with module gaps (gaps without I/O module)
  • Automatic coding of the I/O modules prevents destruction of the electronics if a module is accidentally inserted in the wrong slot during replacement
  • High EMC interference immunity:
    • self-assembling shielded backplane bus
    • multi-layer conductor plate with shield levels for interference-free signal transmission from the terminal to the I/O module
    • system-integrated, space-saving shield connection for quick installation
  • Self-assembling potential groups without external wiring or jumpers
  • Replaceable terminal box
  • Side-by-side latching of the BUs for high mechanical and EMC loads
  • Optional module-specific color identification of the terminals according to the color code CC
  • Optional equipment marking using slide-in equipment labeling plates

An ET 200SP station can be expanded via one ‘BU-Send’ BaseUnit with a “BA-Send” BusAdapter plugged onto it with up to 16 modules from the ET 200AL series of I/O devices with IP67 protection.
