HIMA F7126 990001110 Isolation power module

Product Description

HIMA F7126 (Order No:990001110) is an isolated rack-mounted DC/DC power supply module for HIMA H41q / H51q programmable electronic safety system (PES) from Germany HIMA. It serves as the core power unit of SIS safety instrumented systems. This module converts 24VDC input into isolated 5VDC power for rack backplane, supplying power to CPU and I/O cards. It is equipped with galvanic isolation between input and output, current limiting, overvoltage and short-circuit protection. Redundant parallel operation is supported, certified to IEC61508 SIL3. It is widely used as spare part for safety interlock systems in chemical, oil & gas and power plants.
