6.1
Performance Specifications
This section describes the performance specifications of the I/O module with diagnostic functions in SIL2 mode.
Input module with diagnostic functions
*1 Use an external power supply satisfying the following conditions.
An external power supply has the overvoltage protection function.
The output voltage does not exceed 35VDC when a single fault occurs.
Immediately after power-off of the power supply module, if the input power source is applied to the power
supply module again, the input module with diagnostic functions may not start up. When applying the input
power source to the power supply module again, wait five seconds or more after the shut-off of the power, and
apply the power again.
