Production as well as utilisation of renewable energies is the subject of countless future projects across many industries. A central component of this approach is hydrogen. The electrolysis process required to produce hydrogen can usefully be coupled with the use of renewable energies in many ways to produce green hydrogen in a sustainable manner.
Safely monitoring and controlling the current and voltages is an important component of electrolysis plants. The HVT 300-DV is typically used to make high currents measurable in a safety-oriented manner according to SIL2 via a shunt resistor. Depending on the application, the measuring range and several limit value alarms can be flexibly set via software
Featuring a safety-by-design approach, the HVT 300-DV provides a wide range of diagnostic functions. In order to create a safety loop, the desired output must be evaluated in conjunction with one of the two diagnostic relays REL3/REL4. This way, two individually configurable safety outputs can be created, for which either the relays REL1/REL2 or the 4…20 mA analog output are available.
