•
Response Time
The time interval that PLC from photoelectric couplers energizing (or cutting) to transistor ON
(or OFF) is below 0.2ms.
•
Output current
The current it outputs is 0.3A per point.
•
Open circuit current
Below 0.1mA
E.g.: Below is the connection of controller and stepping driver diagram:
PLC side
(Make sure the driver's photoelectric coupling input terminal has 8~15mA reliable current)
