Modern installation concepts should be designed to save material, costs, time, space, and weight. Products that meet these requirements are therefore absolutely essential.
Weidmüller’s SAI (Sensor-Actuator -Interface) distributors with four, six, or eight connectors are available in various versions. As M12 with 4 or 5-pole design, in M8 and IDC quick-fit connection in 3 or 4-pole design. They are integrated into the relevant machine or plant by "direct installation", have a "flat" design, are sturdy and meet the IP 68 protection class (IP 67 HARAX®).

Input and/or output devices should be introduced into the process directly on the spot to make full use of the cost-saving effects of fieldbus networked I/O systems. Modules of protection class IP 67 should be used if the environment is polluted and/or particularly damp.
Weidmüller’s range of IP 67- SAI active distributors offers a number of new solutions for just such conditions. The modules comprise the passive SAI- (UT) distributors, already successful for a number of years, and a pluggable electronics module. These electronics modules are available for Profibus-DP, CANopen and Interbus. The big advantage of the modular design is the pre-wiring of the passive SAI modules by means of M12 or HARAX® IDC. The decision in favor of a particular fieldbus can be made independent of the wiring of the passive SAI modules. The fieldbus can be changed later without affecting the wiring.

The PROFIBUS-PA is an open field-bus standard (EN 50 170, IEC 1158-2, DIN 19 245). It was specifically developed for the requirements of the Process Industry technology, in particular remote supply and intrinsic safety.
The devices are supplied with power via 2-wire technology with the process data communication being executed digitally. Integration into the PROFIBUS-DP network is carried out by means of a Segment Coupler.
- Reduced wiring costs
- Minimized design costs of the process control system
- Remote interrogation and programming of field devices
- Intrinsically safe version for applications in potentially explosive atmospheres
- Continuing development and support through PROFIBUS User and Trade Organization (PNO)
