JD2912 5-Pin DC Relay, One Normal Open, One Normal Close

Coil voltage: 12V (14V) / 24V (28V) / 36V / 48V

Working current: 10A Ith / CO 5A (continuous operation at 5A)

Wiring Diagram

Contacts Arrangement

Derived and developed from Bosch type automotive DC relay, the JD2912-1Z-xx/10 relays are designed for long term (intermittent switching or continuous load operation in various DC current circuits. Main applications include:

• Automotive
• Industrial control
• Telecommunication remote DC power station
• Photovoltaic energy grid
• Electric vehicle & marine vessel control
• Etc.

KEY FEATURES

• Model:
  • JD2912-1Z-12/10: coil voltage 12V DC; voltage applied on main contacts ≤ 54V DC
  • JD2912-1Z-24/10: coil voltage 24V DC; voltage applied on main contacts ≤ 54V DC
  • JD2912-1Z-36/10: coil voltage 36V DC; voltage applied on main contacts ≤ 54V DC
  • JD2912-1Z-48/10: coil voltage 48V DC; voltage applied on main contacts ≤ 54V DC
• Relay type: SPDT NO/NC (single pole, double throw, one normal open, one normal close) DC relay; could also be used as SPST (single pole, single throw) normal open or normal close relay, by leaving pin 87a or pin 87 not connected.
• Nominal Current Rating: 10A (continuous load 5A)
• Coil Consumption: 1.8W
• Contact Resistance: ≤ 50mΩ
• Isolation Resistance: ≥ 1.0MΩ
• Electric Life: 100,000 times
• Mechanic Life: 10,000,000 times
• Electrical Isolation:
  • Between open contacts: 500VAC
  • Between coil contacts: 500VAC
• Connection: Wires with 1/4" (6.3mm) Spade Contactors
• Working Temperature: -25°C – +100°C
• Product Weight: 32.5g

Wiring recommendations:

• Pin 85 & 86: two terminals for control coil (B+ and B- of DC source of rated coil working voltage, could be reversed except specified by circuit design)
• Pin 30: common main contact terminal (example: DC source inlet or outlet shared by both normal open and normal close loads)
• Pin 87: normal open main contact terminal
• Pin 87a: normal close main contact terminal

Dimensions (unit: mm):

We supply also 40A / 60A Bosch type DC relay JD2912 for intermittent operation applications.

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

• 40A JD2912-S
• 60A JD2912-S
