Wieland adds new input modules to samos Pro Compact familyIn many applications it is essential that analogue variables such as pressure, flow and temperature are monitored in order to ensure safe automation. Wieland Electric has therefore added three new analogue input modules to its samos Pro Compact safety controller family. With these new modules, namely the SP-SAC, SP-SAR4 and SP-SACR22, Wieland has made it possible to reliably detect and further process analogue signals as well as digital signals.

The new modules support sensors with a 0/4-20mA interface as well as temperature-dependent resistors like Pt/Ni sensors and deliver their analogue signals to the samos Pro Compact safety controller. The analogue values can be monitored with the new and reliable Limit, Range, Relation and Difference function blocks in user programs created with the samos Plan 6 licence-free programming software. These efficient function blocks enable comparative or arithmetic operations involving analogue data as well as scaling of the measured current values, and the presentation and visualisation of the analogue values in samos Plan 6.

Integrated USB and ETH interfaces enable access to the system at any time, while Industrial Ethernet protocols have been included from the outset. Further additional gateways for fieldbuses will make any necessary integration into a wide variety of industrial networks simple. This ensures greater transparency for users, as the analogue values can easily be transferred to other control systems. Up to three different fieldbus systems can be operated in parallel from one samos Pro Compact.

These modules are suitable for use in process engineering applications in the glass, metal or chemical industry, or in specific areas of mechanical engineering such as conveyor systems, presses and CNC machines. To ensure safe operation of the system, all inputs and outputs have unique visual displays that clearly show the operating status at any time. The samos Plan 6 software provides a customised report, ensuring that the plant's documentation complies with all applicable regulations. The modules meet all safety standards, including SIL CL 3 according to EN 62061 and PL e / category 4 according to EN ISO 13849-1.
