Each channel carries its own LED status indicator on the front panel for live troubleshooting. Power input runs \u003cstrong\u003e9–24VDC at 1.5A\u003c\/strong\u003e, with an operating range of \u003cstrong\u003e50–122°F\u003c\/strong\u003e and \u003cstrong\u003e0–75% RH non-condensing\u003c\/strong\u003e. The unit attaches to standard DIN rail with the included mounting kit, and Made-in-USA build keeps it serviceable in agricultural environments.\u003c\/p\u003e\n\u003ch2\u003eCentralized 6-Channel Relay Module Wiring for HVAC, Fans, and Pumps\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eUnlike standalone outlet relays, the relayLINK requires a \u003cstrong\u003eGrowlink HUB\u003c\/strong\u003e. Connect via the included 10-foot RJ-45 cable to a free HUB port and the six channels register in Growlink OS within a minute. Place the controller close to the equipment cluster it switches so the dry-contact runs stay short. Daisy-chain the device wires from each Form A (N.O.) terminal back to the controlled gear. The \u003cstrong\u003e6-channel relay module\u003c\/strong\u003e handles mixed-voltage loads cleanly. Wire 24VAC HVAC stage calls on channels 1–2, line-voltage fans on 3–4 through external contactors, and CO2 valves or irrigation solenoids on 5–6. Mapping channels by sub-system rather than device type keeps the wiring diagram readable when adding a seventh or eighth relayLINK to scale beyond six devices. The trade-off is that every relayLINK needs a HUB port — plan port counts first if a build will use multiple modules.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e6x 3.5A Form A (N.O.)
