NOTICE
The safety-related characteristic data applies per channel of the contact ex-
pansion block. The safety-related characteristic data of the base unit and all
other devices that are used must be taken into account when calculating the
safety function. We recommend that you use the PAScal software tool to
calculate the safety function's SIL/PL values.
