Frequently Asked Questions
What's the difference between G6B-47BND and G6B-4BND?
G6B-47BND has 4NO (4 normally open) contacts. G6B-4BND has 4PDT (4 Form C, 4NO+4NC) contacts. Choose 47BND for simple switching applications, 4BND when you need both NO and NC contacts for each pole.
What wire size can I connect to the terminals?
Screw terminals accept 22-14 AWG (0.5-2.5mm²) solid or stranded wire. Use ferrules for stranded wire to prevent fraying. Torque: 0.5-0.6 N·m.
Can I use this relay for motor control?
For small motors under 5A, yes. For larger motors, use relay contacts to control a contactor. Motor loads are highly inductive - consider snubber circuit or varistor for contact protection.
What's the advantage of PCB relay module vs discrete relay?
PCB module includes: terminal block (no separate socket needed), LED indicator, mounting base, and pre-wired connections. Faster installation, cleaner panel layout, easier troubleshooting.
How do I wire the coil and contacts?
Coil terminals: A1 (+) and A2 (-). Contact terminals: numbered per pole (e.g., 11-14 for pole 1). Refer to wiring diagram on relay side. Always use flyback diode across DC coil to suppress voltage spikes.
