Common Technical Questions
- What does “sinking output” mean?
It means the module provides a path to ground. You supply positive voltage to your device. The module completes the circuit to negative. - Does this module have built-in fuses?
No. It does not have internal electronic protection. You must use external fuses to protect each output circuit. - How are the 32 outputs grouped?
They are in two groups of 16. Each group can have its own common connection for wiring flexibility. - Can I use this with a 12V system?
Yes. The wide 5-50V DC range means it works with 12V, 24V, and other DC voltages. - What connector do I need to wire it?
You need a 1746-NC3 connector or a 1492-IFM40xx DIN rail terminal block for easier wiring.
