8 Operation
8.1 Operation
Basic function: binary input / output, 1 and 2 channels.
The I.S. relay module is used to separate the intrinsically safe and non-intrinsically safe
signal and control circuits.
Depending on the version, the intrinsically safe electric circuits are used for the activation or
transmission of the control signals.
8.2 Indications
The LEDs on the device indicate the operating state of the device
(see also the "Device design" chapter).
Operation under difficult conditions, in particular on ships, requires additional
measures to be taken for correct installation, depending on the operating location.
