Description
The HVT 300-SIL-DX is used e.g. for balance voltage monitoring in chlor-alkali electrolysis
systems or as a voltage converter in test systems for the automotive sector. The redundant
measuring input enables self-monitoring for the reliable detection of an error. The absolute
value of the measured DC voltage is output as a 0 / 4-20 mA signal.
For signaling the safety function, 2 relays and the mA output are available, which can be
interconnected with each other or with the alarm outputs 1 and 2.
WARNING: high voltage / risk of death
The device is electrical equipment with voltage inputs for up to 1000 VDC. It is
designed for use in secure operating environments. The specified safety conditions
must be observed for installation and operation and security policies (including
national security policies), accident prevention regulations and general technical
regulations are observed. Please also note the safety regulations and instructions
for Installation on page 4 and 5.
