TTL is 0-5V logic where 0V is low, and 5V is high. With 24V logic, 0V is low and 24V is high.
Application
- With the wider voltage swing, 24V logic is more noise immune
ADVANCED Motion Controls' Capabilities
- Drive models that feature either TTL or 24 VDC logic interfaces are offered
- 24 VDC interface is more common with drives rated to higher voltages
