Technical questions on Crydom solid state relay

I'm looking for a solid state 12vdc (input & output) relay with a high output current rating; up to 100A if possible. Can you provide p/n & specs of your highest 12vdc output current rated SS relay?
The highest DC output current is 40ADC. The part number is CRYDOM: D1D40.
Input:3.5-32VDC Output:0-100VDC, 40ADC

I need relay with:

  • 12Vdc coil voltage
  • 400 Vdc contact Voltage
  • less than 0.500 A contact Current
  • 2 poles, normaly Open/Disconnected

Do you have any of your products that muching my requests?
As you need 400VDC load voltage, the most suitable solid state relay is CRYDOM Part No. D4D07 (control voltage 3.5-32VDC , output 400VDC, 7Adc)

I've been using a D2524-B for years. Lately it's been getting harder to find every time I try
Is that part going obsolete or should I be using something else?
I think you are using D2425-B not D2524-B.
D2425-B is a normal close relay, which is an uncommon item (i.e. no stock - longer leadtime).
If possible pls design to use standard relay D2425 (normal open) to replace D2425-B.

I need more information on part: cryd-DO061B. what's the input voltage?
DO061B - Control input voltage: (1.7-9Vdc) output: (3-60VDC), 1Adc.
If the output current is less than 1Adc. DO061B is OK to use.
Solid State relay is normally used in normal open application.

I am looking for a crydom TD1210. Is that the same as the D1210?
Yes,You can use D1210 or D2410 for substitution.
The operating voltage of D2410 is 24-280VAC and TD1210 is 24-140VAC, D1210 is 24-140VAC
The other specification are the same.
