ZH842H Series
Solid-state high-voltage signalling relay
The ZH842 H Series solid-state high-voltage sensor signals high voltage applied to the train line. The device supplies electrical loads, which for the conservation of battery power are only operated when high voltage is being applied, with control voltage.
Mode of operation: The ZH842 H switches on a potential-free relay contact as long as the high voltage at the input terminals exceeds the signalling voltage.
Features
- Identification of UIC 550 compliant voltages (1 kV 16 ⅔ Hz / 1.5 kV 50 Hz / 1.5 kV DC / 3 kV DC) and 3 kV 50 Hz
- Meets insulation requirements for 3 kV DC (UIC 550) according to EN 50124-1:2001+A1
- Low stand-by consumption
- Potential-free switching output
