System gesis FLEX - The fused 2-fold shutter output 24 VDC/3A, with flat surface mounted housing which can be fitted on DIN rail for decentralized installation, is managed by the base module. It receives the internal supply from the upstream module. The 24 VDC supply is externally and fused with a 6.3 AT fine-wire-fuse. The parameter set enables different automation functions. The manual operation level allows functional testing without prior system integration. The electrical connections are pluggable in accordance with IEC 61535, separate automation and installation.
