Voltage Transmitter for Shunt Monitoring HVT 300-DV-1

rmiiteci I Your safe choice HVT 300-DV Failsafe Voltage Monitor for shunt monitoring Chlorine Alkaline Electrolysis PEM Electrolysis High Power Rectifiers Power Rails Production as well as utilization 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 SIL 2 via a shunt resistor. Depending on the application, the measuring range and several limit value alarms can be flexibly set via software.

Voltage Transmitter for Shunt Monitoring HVT 300-DV-2

Technical Data 1 miitec i I Your sate choice 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. Main Benefits - Failsafe voltage monitoring - Simple software configuration via USB or Modbus RTU - 0-70 mV DC measurement range - Redundant architecture - Robust...
