FAQ

Q: What is negative logic sink input?

A: The module reads signals referenced to ground. Current sinks from input to common when activated.

Q: How does 140DDI35310C differ from 140DDI35300C?

A: 140DDI35310C uses negative logic. 140DDI35300C uses positive logic. Choose based on your field device wiring.

Q: What is the maximum input voltage?

A: Continuous input is 30V DC. The module survives 50V for 1ms decaying pulses without damage.
