System gesis FLEX - The 4-fold semiconductor output 24 VDC/0.5 A output, with flat surface mounted housing which can be fitted on DIN rails for decentralized installation, is managed by the base module. Each output is electronically fused. Bus and power supply are from the upstream module, the 24 VDC has to be fed separately. The extensive 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. All necessary plugs are enclosed.
