Process Interface

The Process Interface, Phoenix Contact's product innovation, comprises a slimline 12.4 mm interface isolating terminal and plug-in, encodable electronic modules, which are also 12.4 mm wide. This enables the user to save space and reduces the time required for installation. The electronic connectors have been realised in accordance with the intrinsically safe protection class. The basic terminals are equipped with testing facilities for each cable and isolating blades on the panel side. This means that a measuring device can be looped into the signalling path for diagnostic purposes. Jumpers ensure a fast, reliable supply of power. One of the benefits for the user is the modularity of this system as, unlike multi-channel 19"plugin boards, he only needs to fit the actual number of process interface modules required at the time of commissioning and therefore does not incur any supplementary costs for channels that are not used. Another advantage of this concept is its prewiring capability, whereby the basic terminal is fitted into the wiring cabinet directly, without the plug-in electronics. The corresponding encodable electronic connector is fitted at a later stage, which means that the costs of this are not incurred until the system is actually commissioned. It is also possible to fit a reserve in the switchgear cabinet. The new Process Interface concept begins with intrinsically sate analogue output and input modules with smart capability, as well as programmable temperature transformers. Configurable analogue isolation amplifiers, feed-isolators and NAMUR switching amplifiers for signals, that are not subject to the requirements for hazardous duty, round up the range.
