Product description
Switch amplifiers of the series TS125 and TS255 are used in switch cabinets for
the conversion and isolation of digital switching signals, optionally also in explosive
areas.
The devices are available in one- or two-channel versions.
All passive sensors, such as switching contacts, Namur initiators according to DIN
EN 60947-5-6, or passive electronic outputs of third-party devices, can be
connected to the optional intrinsically safe inputs.
The TS125 series in 12.5mm wide carrier rail housing offers relay outputs with
output make circuit.
The TS225 series in 22.5mm wide carrier rail housing offers relay outputs with
changeover function.
The devices may also be used in explosion zone 2 if they are installed in a suitable
housing.
Use in plants with functional safety SIL2 is also possible.
