Isolated Digital Input

Isolated digital input utilizes an open collector transistor structure,
with input voltage range of 0 V to 24 V and input resistance of 2.4K
Ω. Connection between external signals and the MXC-4002D/
4011D controller is as shown.
Note:
The common input junction can be common ground or
common power, based on the applied environment, such
that digital input can be either a current source or current
sink.
