Signal conditioner system expansion

The 6mm wide signal conditioner from Pepperl+Fuchs is now supplemented by two additional modules. A new universal splitter is used for the galvanic isolation, conversion, and distribution of standard signals in the 0/4 mA … 20 mA, 0/1 V … 5 V, and 0/2 V … 10 V range. 

The measurement input provides a supply voltage for the operation of 2-wire signal converters. Among the new features of this device are the universal analog outputs that can output current or voltage signals. 

These outputs allow operators to use a significantly larger number of field devices and controllers on this module compared to conventional current signal splitters, since several types of signals can be processed.

A millivolt signal converter has also been developed. The millivolt signal converter strengthens bipolar and unipolar millivolt voltages, which often occur in applications where sensor voltages are low, e.g., when measuring currents using shunt resistors. 

As a result, ten signal conditioners are available in the SC-System for all analog measuring signals, from the isolating amplifier to the passive isolator to the highly functional temperature converter.

The SC-System features high-quality 3-way isolation between input, output, and supply that can withstand an operating voltage of up to 300V and a test voltage of up to 3.0kV. 

The large temperature range of up to 70 °C in which the products can be operated is guaranteed by the low-power design, ensuring low self-heating. 

Effective use of switch cabinet space when using the SC-System is achieved with a compact design: The housings, which are just 6mm wide, reduce the space requirements of the signal conditioner modules to a minimum. 

With a housing height of only 97mm, the signal conditioner line is one of the most compact systems of its kind and ensures that the modules can be fitted between narrow-seated cable ducts.

Extensive tests in a separate, independent testing laboratory ensure that the products can also withstand high mechanical loads, such as those that may be created in close proximity to piston engines or crushing plants.
