2.2.3 CN2 Port type
1. Digital input interface
DC12V
~
24V
。
Digital input interface circuit by switch, relay,
open collector triode, photoelectric coupler of control. Relay required to choose low current relay, in order to
avoid the phenomenon of poor contact. External voltage range DC12V ~ 24 V.
2. Digital output interface
Output circuit adopts darlington photoelectric coupler, but with relay, photoelectric coupler
Note:
●
External power supply by users, but must pay attention to, if the power polarity meet back, may cause damage to
the servo driver.
●
When the output open collector form, the maximum current is 70 mA, the external power peak voltage
is
25 V. If
more than limit requirements or output directly with power connection, may cause damage to the servo driver.
