Product details

Module for PROFIBUS DP 8DI/8DO Slots

The Siemens 6ES7143-1BF00-0AB0 is a SIMATIC DP module providing 8 digital inputs and 8 digital outputs over PROFIBUS DP. Input voltage for signal '1' is 13 to 30 V; for signal '0' the threshold varies by pin—-3 to +5 V on the parameterized DI pin, -30 to +5 V on the input-function pin. Typical power loss is 3.5 W. Diagnostic alarm and short-circuit protection are included, with a red group-error LED (SF). Transmission rate supports 9,6 kbit/s to 12 Mbit/s over PROFIBUS DP. Unshielded cable length is rated to 30 m. The module is a PROFIBUS DP slave.
