Notes

1. Input current measured at nominal input voltage.

2. Typical values.

3. For optional version fitted with DIN Clip add suffix ‘-D’ e.g. DTJ2024S12-D.

4. For optional factory fitted heatsink add suffix ‘-HK’ e.g. DTJ2024S12-HK or

DTJ2024S12-HKD with DIN clip.

5. Input current is typically 2.0mA at nominal input voltage when output is remotely

turned off.

6. Per output.
