As a compact single-width module (25 mm wide), it fits into the S7-400 rack and draws 0.6 A at 5 V from the backplane bus, consuming 3 W. The module’s DP master capability is subject to system constraints: up to 10 CPs can be operated in total, with up to 4 serving as PROFINET IO controllers (if compatible CP 443-1 Advanced are present) and up to 10 as DP masters. Operating temperature range is 0...60 °C, storage/transport -40...70 °C, protection class IP20.","metaTitle":"Siemens 6GK7443-5DX05-0XE1 CP 443-5 Extended, DPV1","metaDescription":"PROFIBUS DP communications processor for S7-400, DPV1, conformal coating, single-width module, 0.6A at 5V from backplane.
