Switch amplifiers of the series TS125 and TW255 are used in
switch cabinets for the conversion and isolation of digital switching
signals, as well as in explosion-prone areas.
The devices are available in one- or two-channel versions.
Passive sensors, such as switching contacts, Namur initiators, or
passive electronic outputs of third-party devices, can be connected
to the intrinsically safe inputs.
