Product Overview
Siemens 6ES7131-6BF01-0AA0 is a SIMATIC ET 200SP Basic digital input module with eight 24 V DC sink inputs for PNP, P-reading field devices. It fits BaseUnit type A0 and provides a parameterizable input delay from 0.05 to 20 ms for adapting signal filtering to the application. The module follows IEC 61131 type 2 input characteristics and uses color code CC01. It supports I&M0 to I&M3 identification data and is integrated in STEP 7 TIA Portal from version V14. Procurement should verify the complete MLFB, BaseUnit wiring variant, sensor logic, voltage range and engineering environment.
