control output signal. Therefore, the processor board has a common line for two separate circuits:
COM1 and COM2.
The electrical characteristics of the DC isolated output are divided into two types, see Table 10-4.
The output circuit configuration of the test result output signal is shown in Figure 10-5, and the
output circuit configuration of the control output signal is shown in Figure 10-4.
