Details

The voltage relay is designed with a microcontroller. With programmable range, function and timing it can be programmed to cover a wide range of applications. The voltage to be monitored is fed into a resistive divider and, for extreme noise immunity, amplified in a balanced amplifier, rectified, averaged, and compared with a preset reference voltage. AC and DC voltages between 50mV and 500V can be measured directly by means of a voltage transformer or a resistive divider the range can be extended without limits.

For applications in DC systems a special feature of the balanced amplifier permits voltages against the negative supply line to be measured directly without DC separation between input and supply.

Application
Level comparator used with transducers and transmitters. Over or undervoltage monitoring of loads, batteries, generators, mains etc.
