Galvanic isolation
● For basic device without Ex
protection and for basic
device with Ex d
Galvanic isolation between the basic device and the input for safety shutdown and the
outputs of option modules.
● For basic device Ex "ia"
The basic device, the input for safety shutdown, and the outputs of option modules are
individual intrinsically safe circuits.
