Place an inline fuse holder or DC breaker directly on the positive wire, situated as close to the 24V power supply source as possible.
: Indicates the operating voltage (usually 24VDC for control circuits). It is critical to verify if your system is AC or DC before wiring. Installation & Wiring Basics f4901 11a 24v schematic install
| Mistake | Consequence | |----------------------------------|--------------------------------------| | Reversing IN+ and GND | Destroys reverse polarity MOSFET | | CTRL left floating | Output stays off (internal pull‑down)| | No flyback diode on relay coil | Voltage spike damages output MOSFET | | Using 18 AWG wire for 11A | Excessive voltage drop, fire hazard | Place an inline fuse holder or DC breaker
Typically available in SPDT (Single Pole Double Throw / 1 Form C) or DPDT (Double Pole Double Throw / 2 Form C). Installation & Wiring Basics | Mistake | Consequence
