OMRON ELECTRONIC COMPONENTS G9EB-1-BDC24

G9EB-1 DC Power Relays (25-A Models) DC Power Relays Capable of Interrupting High-voltage, High-current DC Load • Utilizes a unique gas-filled, fully sealed, non-ceramic construction achieved by using resin with a metal case. This reduces the need for special processing and materials that were required with previous models, resulting in a low-cost relay that is both compact and lightweight. • Smallest and lightest in its class at 25 × 60 × 58 mm and approximately 135 g. This is approximately half the volume and a third of the weight of other DC Power Relays in the same class (400 VDC, 25 A).* • The unique design of the contact switching component and permanent magnet for blowing out the arc eliminates the need for polarity in the main circuit (contact terminal). This improves ease of wiring and installation, and contributes to providing failsafe measures against incorrect wiring. * Based on our investigation as of December 2004. RoHS Compliant Refer to "DC Power Relays Common Precautions". ■Model Number Legend 1. Number of Poles 3. Coil Terminals G9EB-@-@-@-@ — — — — B: M4 screw terminals 1: 1 pole 12 3 4 G 2.

The above values are initial values at an ambient temperature of 23°C unless otherwise specified. *1. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method. *2. The insulation resistance was measured with a 500-VDC megohmmeter. G *3. The impulse withstand voltage was measured with a JEC-212 (1981) standard impulse voltage waveform (1.2 × 50 μs). 9 *4. The mechanical endurance was measured at a switching frequency of 3,600 operations/hr. E *5. The electrical endurance was measured at a switching frequency of 60 operations/hr. B *6. These values are for when a varistor is used as the protective circuit against reverse surge in the relay coil. Using a diode will reduce theswitching characteristics. 1 2 - G9EB-1 DC Power Relays (25-A Models) ■Engineering Data G9EB-1-B Switching/Current Conduction Models ● Maximum Switching Capacity ● Electrical Endurance (Switching ● Electrical Endurance (Interruption Performance) Performance) 1,000 100 100 500 50 50 DC resistive load 300 30 Switching 250-VDC resistive load 30 100 10 Interrupting 250-VDC resistive load 50 5 10 30 3 5 10 1 5 3 0.5 3 0.3 1 1 0.1 10 30 50 100 300 500 1,000 10 30 50 100 300 500 1,000 10 30 50 100 300 500 1,000 Switching voltage (V) Switching current (A) Switching current (A) ● Carry Current vs Energizing Time ● Must-operate Voltage and ● Time Characteristic Distributions Must-release Voltage Distributions 100,000 30 60 Sample: G9EB-1-B 12 VDC Sample: G9EB-1-B 12 VDC Must-operate voltage Operate time 50,000 Number: 50 Number: 50 Must-release voltage Release time 25 50 30,000 10,000 20 40 5,000 15 3,000 30 1,000 10 20 G 9 500 E 300 5 10 B 100 10 30 50 100 300 500 1,000 0 10 20 30 40 50 60 04 8 12 16 20 1 Carry current (A) Percentage of rated voltage (%) Time (ms) ● Vibration Malfunction ● Vibration Resistances 1 5.0 Sample: G9EB-1-B 12 VDC Sample: G9EB-1-B 12 VDC Number: 5 Number: 5 0.9 4.0 Unconfirmed area 0.8 3.0 0.7 2.0 0.6 1.0 Must-release voltage 0.5 0.0 Must-operate voltage Confirmed area 0.4 −1.0 0.3 −2.0 0.2 −3.0 0.1 −4.0 0 −5.0 11 3 503050 100 Start After test Characteristics were measured after applying vibration Frequency (Hz) at a frequency of 10 to 55 Hz (single amplitude of 0.75 mm) to the test piece (not energized) for 2 hours each in 3 directions.
