Galvanic isolation between the basic device and the input for safety shutdown and the
outputs of option modules.
The basic device, the input for safety shutdown, and the outputs of option modules are
individual intrinsically safe circuits.
Galvanic isolation between the basic device and the input for safety shutdown and the
outputs of option modules.
Layers 1 + 2 as per PROFIBUS PA, transmission technique as per IEC 1158-2;
