Derating Curves for 3.3 V

(No Baseplate)

1. Standard product is open frame with negative logic.

2. Baseplate versions are built to order.

3. Please add one of the following suffix codes to the model number when ordering: ‘AL’ = Open Frame/Negative logic,
‘AH’ = Open Frame/Positive logic, ‘BL’ = Baseplate/Negative logic, ‘BH’ = Baseplate/Positive logic.

4. For input reverse voltage protection, use a parallel diode across the input terminals preceded by a 10 A fuse.

5. For details on external filtering, contact technical sales.
