JD2912, 5-Pin DC Relay & 4-Pin DC Relay

Working voltage: 6V / 12V (14V) / 24V (28V) / 36V / 48V / 60V / 72V

Working current: 40A Ith / 60A Ith

Attention: the DC relay JD2912 is designed for intemittent DC power switching applications. It is not recommended to use JD2912 as main power switch for high power continuous load. Typically, JD2912 is used as control device of main DC power switching solenoid or contactor （control the "ON / OFF" operations by feeding or cutting off power to the coid of solenoid or contactor).

The current holding capacity of JD2912 decreases steeply when the voltage rises.

Derived and developed from Bosch type automotive DC relay, JD2912 relays are widely used in various DC current switching circuits. Main applications include:

• Automotive light & horn
• Engine starter
• Telecommunication remote DC power station
• Photovoltaic energy grid
• Electric vehicle & marine vessel control
• Etc.

Loading Test Curve (40A Max.):

There are 4 types of JD2912:

1. Standard type
2. Resistant type
3. Diode (D) type
4. Diode (DC) type

By default, the DC relays sold are stardard type. If you want the relays of "resistant type", "diode (D) type" or "diode (DC) type", please contact us for more details about price and shipping delay.

Waterproof DC relay JD2912-S ("S" means "sealed") is also available:

• 40A JD2912-S
• 60A JD2912-S
