External Relay

The External Relay is a four-relay device compatible with the 180-SMHR2, 180-SMA2, and 180-MC product lines.

The relay is controlled and programmed through the WebUI of the attached 180 Device and can be programmed to enable or disable a relay on seismic trigger activation. 

Each relay has terminal blocks that can be wired in normally open or normally closed configurations and are capable of switching loads up to 15 Amps for 12V (DC), 24V (DC), and 125V (AC) circuits. For 250 (AC) circuits the maximum load is 10A.
