The Hochiki R2ML-I is a DCP-addressable dual-relay module with a built-in short-circuit isolator. It provides two independently controlled Form C contacts per SLC address.
First, the R2ML-I integrates the same dual low-current relays as the R2ML. Then it adds an SLC isolator that opens during a downstream short. As a result, a single short does not disable the rest of the loop.
Hochiki R2ML-I Isolator Behavior
Specifically, a yellow LED on the faceplate lights when the isolator trips. In addition, the SCI on-resistance is 40 milliohm max during normal operation. However, the isolator returns automatically once the short clears.

Typical Applications
Furthermore, the R2ML-I suits the same low-current auxiliary duties as the R2ML. Also, the integrated isolator removes the need for a separate DCP-SCI device adjacent to the module. Therefore, both panel space and SLC address count benefit.
