In the two analog input circuits: AD1 is accurate to 16 bits (optional, applicable only to standard models)
and AD2 is accurate to 12 bits (preconfigured for standard models); the input impedance is 10kΩ, and
the input voltage ranges from -10V to +10V. If the voltage is ±11V less or greater, the circuit may be
damaged.

⚫ There are six digital output circuits in total, which use the open-collector output structure as shown
in the figure. They can be used to drive the relay coil or optical coupler load. The loading capacity
is shown in the figure.
⚫ If an inductive load such as the relay coil is connected, a free-wheeling diode must be connected,
as shown in the figure. If an optical coupler is connected, a current limit resistor must be connected.
Otherwise, the drive may be damaged.
