Product details

PROFIBUS DP Digital I/O Module for ET 200pro

The Siemens 6ES7143-1BF00-0XB0 is an ET 200pro digital input/output module connecting as a PROFIBUS DP slave. It provides 8 process channels, parameterizable as digital inputs or outputs, plus 8 function channels for diagnostics or NC input assignment. Inputs accept signal "1" from 13 to 30 VDC and signal "0" from -3 to +5 V (or -30 to +2 V for input functionality). The nominal supply is 24 VDC with a typical power loss of 3.5 W. Short-circuit protection is electronic, with a typical response threshold of 1.8 A. PROFIBUS DP transmission rates are selectable from 9,6 kbit/s up to 12 Mbit/s. SYNC and FREEZE capabilities are supported. A diagnostic alarm, group error SF (red) LED, and per-channel status indicators are built in.

This module is in active current production per the lifecycle record.
