2 Product Specifications

2.1 Function

Isolated barriers are isolators used for protection of intrinsically safe circuits in hazardous

areas. In addition to the required current, voltage and power limitation, the isolated barriers

have a galvanic isolation between the field circuit and the controller.

Figure 2.1 Function – isolating, amplifying and transforming signals

The K-System consists of wide range of isolated barriers suitable for mounting on 35 mm

DIN mounting rail. K-System is easy to specify, integrate and expand. Our extensive line

of intrinsic safe isolators for hazardous location applications contains over 150 different

devices.

2.2 Housing Styles

Depending on the functionality and application, K-System devices have 3 different housing

widths:

•KC devices with 12.5 mm width

•KF devices with 20 mm width

•KF devices or KH devices with 40 mm width

The 3 housing widths versions have the same system characteristics. All devices

can be mounted on the 35 mm DIN mounting rail or the Power Rail. See chapter 2.9
