1.
Analog input terminal
As analogy voltage signals can be easily affected by external interference,
shielded cables shall be used. Cables shall be as short as possible and not exceeding 20
meters. As shown in Graph 2-12 & 2-13, in some severe circumstances, filter
capacitor or ferrite bread shall be used in analog signal side.

Digital input terminal
Shielded cables shall be used. Cables shall be as short as possible and not
exceeding 20 meters. When using active drive mode, user shall take necessary filter
measures to counter power interference. It is recommended to use node control mode.
Digital inputs include NPN input and PNP input.

NPN input:Most common. Use internal 24V power; +24V terminal
short-circuit with SP terminal; COM terminal is common;J9 is 23 jumper; also known
as drain wiring mode.
