SIGA-CT2

The Edwards SIGA-CT2 is an intelligent dual input module from the Signature Series, designed to interface one or two Class B normally-open dry contact initiating device circuits (IDCs) with Signature Loop controllers for alarm, supervisory, or monitor applications.
It features microprocessor-based signal analysis with configurable personality codes downloaded from the loop controller, providing automatic device mapping, ground fault detection by address, and non-volatile memory for reliable standalone operation.
