Note ①
: The rated current of one-way 24V DC output power supply is 1A;
The 24V DC output power supply cannot be connect to external
devices, but can only be used for I/O output.
Figure 4-7
Diagram of input circuit (left) and output circuit (right)
1. DO indicates open-circuit output mode (NPN), with maximum
frequency of 1 kHz, and maximum current of less than 200 mA;
2. When the 24V DC output power supply of the I/O connector is
used in conjunction with the DO, it serves as an active output to
provide energy to the outside and can be connected to resistive,
inductive and capacitive loads.
However, the one-way 24V DC output
power supply can be used in conjunction with up to 4-way DO at the
same time, with maximum current of less than 1A, otherwise the
internal protection circuit of the system would be burnt out due to
overcurrent.
3. To ensure reliable and stable operation of the load, it should
be connected to an external 24V power supply in conjunction with
DO.
