Example I/O signal connections
This is only a connection example for CN8. Refer to the following for other connection examples.
Page 40 Example I/O signal connections
Input signal
There is a delay of up to 5 ms from input to output.
For source input interface
For sink input interface
*1 Separate the external input wiring into two routes, SDIA and SDIB.
*2 Supply interfaces with 24 V DC ± 10 % from external sources. If all the I/O points have been used there must be a total current capacity
of 0.2 A remaining. Reducing the number of I/O points decreases the current capacity. Refer to section 9.6 for information on the
voltages required for interfaces. Although the diagram shows the input signal and the output signal each using a separate 24 V DC
power supply for illustrative purposes, the system can be configured to use a single 24 V DC power supply.
Output signal
For source output interface
For sink output interface
*1 Separate the external output wiring into two routes, SDOA and SDOB.
*2 Supply interfaces with 24 V DC ± 10 % from external sources. If all the I/O points have been used there must be a total current capacity
of 0.2 A remaining. Reducing the number of I/O points decreases the current capacity. Refer to section 9.6 for information on the
voltages required for interfaces. Although the diagram shows the input signal and the output signal each using a separate 24 V DC
