Rcoil - The resistance of the solenoid coil at
Tambient in degrees C
- Loop current in the circuit, which may be
calculated as follows:
= 320 ohms x (Tambient + 234)
254
Vsupply
(Rcoil + Rloop + Rbarrier) =
Iloop
Iloop
Rloop - Resistance of the lead wires
Rbarrier - Internal resistance of the barrier
- Supply voltage Vsupply
Where:
Rcoil
This current must always be greater than or equal to 0.030 amps
for proper operation of the solenoid valve.
