Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 3SU1400-1LL10-1BA1 is a SIRIUS ACT fail-safe interface module with PROFINET support, manufactured by Siemens. It provides four digital inputs (DI), one digital output (DQ, 24 V DC), and one 12-bit analog input (AI), enabling safe transmission and monitoring of machine states over Industrial Ethernet. Typically mounted on front plates, it connects up to 20 terminal modules. This module is used within safety control architectures requiring PROFINET IO and PROFIsafe integration, particularly in machinery safety and fail-safe system expansion.
