Chapter 3 Interfaces and Wirings of CD Driver
3.1 Interfaces of CD Driver
Table 3-1 Interfaces of a CD driver
External logic power (24 V +/- 15%) interface with a minimum
of 0.5 A current output
Common port of digital input signals
Digital input interface
Valid signal: 12.5 V ~ 24 V
Invalid signal: less than 5 V
Pulse or positive pulse
interface (+)
Input voltage range: 3 V to 5 V
If the input voltage is 24 V, the
interface is cascaded to the 2K
resistance.
