Abstract
A circuit for providing input surge protection in a digital input module, the circuit comprising a surge protection input stage, including a bridge rectifier coupled to receive the bidirectional input signal, and coupled to the unidirectional input of the digital input module. The bridge rectifier comprises TVS rectifiers TVSand TVS, and diode rectifiers Dand D, intercoupled in a bridge rectifier configuration in which: TVSand TVSare transient voltage suppression diodes; and rectifiers Dand Dare rectifier diodes. Diodes TVSand TVScan be implemented as either respective unidirectional TVS diodes; or a single bidirectional TVS diode. The digital input module can be a digital input receiver, or a opto-isolator/coupler, or other digital input module.
