Product details

The Siemens 6ES7141-1BF01-0AB0 is a digital input/output module with 8 inputs and 8 outputs, a PROFIBUS DP interface, and an active lifecycle status. It runs on 24 V DC and draws 180 mA from the 5 V backplane bus.

The module supports diagnostic alarms, a parameterizable diagnostics function, and status LEDs per digital input (green). It also includes FREEZE and SYNC capabilities for synchronized acquisition.

Mounting and expansion

Dimensions change depending on mounting: screw-mounted reduces depth from 110 mm to 90 mm, width from 175 mm to 180 mm, and height from 180 mm to 174 mm. Account for these two sets when laying out the panel and routing wiring. Expand up to 7 additional modules (including a maximum of 6 pneumatic interface modules) on the same rack. The PROFIBUS DP interface handles up to 12 Mbit/s; transmission rate is set automatically.
