The contact is open when the relay coil is off and closes to make a connection when the coil is energized.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCan I switch 120V AC with this module?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNo.\u003c\/b\u003e The relay contacts are rated for a maximum of \u003cb\u003e30V AC or 28.8V DC\u003c\/b\u003e. Applying higher voltage will damage the module and is a safety hazard. For higher voltages, use this relay to control an intermediate contactor.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhy is there a minimum load requirement?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eA very small load (\u0026lt;100 µA) may not provide enough current to \"wet\" the contacts and break through surface oxidation, leading to unreliable switching. For dry circuit applications, use gold-plated relay contacts.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow do the status LEDs work?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eEach green LED turns on when its corresponding relay coil is energized by the module's logic, indicating a command to close the contact. It does not confirm the physical contact has closed or that load current is flowing.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat is the main advantage over solid-state outputs?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe key advantage is \u003cb\u003ecomplete galvanic isolation\u003c\/b\u003e and the ability to switch AC or DC loads of different voltages on the same module. Solid-state outputs are typically faster and have longer life but are usually restricted to DC and one polarity.\u003c\/p\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
