The E-Plex 172QR Quad Relay Module contains four relay contacts in a small, din rail mountable box which
connects directly to the E-Plex bus with no special interfacing. Each relay can drive up to 130VAC at 10A
with no external components.
The 172QR requires a third bus wire connection to supply power to the relays. The quad relay module’s
operating range is from 10V to 30V on the E-Plex bus.
