Edwards iO-SDC1 Addressable Single Loop Controller Card (NEW)
Edwards iO-SDC1 Single Loop Controller Card – Expandable SLC Module for iO64 & iO1000 Panels
The Edwards iO-SDC1 is a versatile single loop controller card designed to enhance the capacity and flexibility of Edwards iO fire alarm systems. It serves as a direct replacement for the standard 64-point loop on the iO64 panel, or as a 250-point expansion module for the iO1000, supporting up to 250 intelligent devices on a single SLC.
Engineered for performance and reliability, the iO-SDC1 supports Class A or Class B wiring, up to 64 isolators per loop, and operates with a maximum loop resistance of 66 ohms. Ideal for scalable fire alarm installations, it delivers efficient communication, diagnostic precision, and robust circuit support—all in a compact form factor.
