Sự khác biệt giữa Line Drive và Open Collector?

Q: What is the difference between Line Drive and Open Collector types for CIMON PLC?

A: Line Drive and Open Collector types become different according to the input and output signal method of an Encoder.

[Line Drive]

– Use only 5V.
– Use 4-wire circuit and is resistant to external noise.
– Widely used for AC servo motors due to the use of high frequency band.
– Use +, – balanced signal and is able to do high speed control.
– Less restrictions on the wiring distance between amplifier and encoder.

[Open Collector]

– Use different voltage from 5 to 24V.
– Input method is single signal.
– Commonly used for relatively low-speed stepping motors
