The Voltage to Frequency Converter Using as Reference the Pull-In Voltage of a Reed Relay

F. Castelli, M. Faifer

Abstract

The chief requirements of basic components of digital systems for industry are both the availability of preventive maintenance and high reliability. Integrated semiconductor components are highly lacking in both these requirements. To respond to the referred exigencies a voltage to frequency converter (VFC) by the use of a reed relay (RR) and a charge-discharge method with as reference the pull-in voltage of RR is illustrated. Test results prove a high linearity and that it is imperious to environmental temperature and proper for extreme environmental industrial conditions.
