Relay module — 4 channels
Four relays, two RJ45 pairs, two GX12 outputs. Yellow case.
v2.0
Available
Same enclosure family as the 2-channel module, scaled width to fit the 4-channel relay PCB (73×50 mm with M3 holes at 67×44.5 mm spacing). Two pairs of RJ45 jacks on the front panel for two independent loopthroughs, and two GX12 power connectors for separate switched circuits. The optional LED window passes four LEDs in adjacent labyrinth-in-Z tunnels (~9.3 mm spacing) without leaking light between channels.
