Field Wiring
120 VAC LED lamp
High impedance lamps such
as LED lamps require a 15 k
Ω
1W 5% resistor in parallel to
the lamp to prevent current
leakage.
120 VAC coil
Install a 120 V MOV surge
protector in parallel with
solenoid coil to suppress
noise.
24 VDC coil
Install a 1N4007 reverse
polarizing diode in parallel
with DC solenoid coil to
suppress flyback voltage.
