Question

What is the recommended replacement product for G3N Solid-state Relays?

Answer



1.The recommended replacement product depends on the model of G3N. Check with the following table.

Note:

1.If a heat sink was used, select a replacement product that uses the same heat sink.

2.There is no replacement product because the discontinued models were designed for a 3-VDC input voltage, but the replacement models are designed for 4 VDC. Replacement from 3 VDC to 4 VDC is not possible.

3."DC4-30" in the discontinued model number indicates the input operating voltage (4 to 30 VDC), while "DC5-24" in the recommended replacement model number indicates the input rated voltage. The input operating voltage is 4 to 32 VDC. Therefore the recommended replacement model covers the specifications of the discontinued model. Similarly, for models with a rated input voltage of 100 to 120 VAC, the input operating voltage is 75 to 132 VAC, and for models with a rated input voltage of 200 to 240 VAC, it is 150 to 264 VAC.

Note:If G3N-240B has been used, it is necessary to create mounting holes for the panel or heat sink. However, by using R99-11 Mounting Brackets, the same pitch can be used.
