DDNS Negative (-) Dual Diode SwitchFEATURES Shooting line color: White Detonator line color: Red/Blue Ground line color(Optional): Black Downhole pin: Brass pin SPECIFICATIONS Part Number: SF Switch-DDNS Max. Pressure: 15,000 psi (103 MPa) Max. Temp.: 177°C(350°F) Max. Voltage : 600 VDC Max. Current : 2,000 mA INSTRUCTION Dual Diode Switch is installed in bulkhead body. It can pass negative (-) current to detonator in lower gun and positive (+)current to detonator in upper gun. The polarity of the upper and lower detonator connections cannot be changed by the operator. The white wire on a dual diode must always be connected to the shooting line. If the upper detonator and shooting line are reversed, both detonators will be fired at once. INSPECTION METHODS |
