Function

This signal conditioner provides the galvanic isolation beetween field circuits and control circuits.
The device switches circuits on the field side. Typical applications for the use of the device are remote reset, fire alarm testing or
remote calibration of strain gauges.
The outputs are galvanically isolated to the inputs. The inputs are not polarized and share a common reference potential.
Each input of the device is protected by a fuse and an electronic current limiting.
