Product details

The 6AG1900-0AB01-4AA0: SIPLUS C-Plug 256 stores configuration and engineering data for CP 343-1 Advanced. Conformal coating and resistance to coolants and lubricants let it operate in environments where standard C-Plugs would fail — 0 to 60 °C, IP20.

Integration and protection

Slots directly into the compatible processor; no additional wiring needed. Compact footprint of 24.3 × 17 × 8.1 mm fits into tight panel space. Conformal coating and Type 1 protection against fouling qualify it for atmospheres with industrial contaminants.
