FIEPOS model FPT300.246-042-101 meets the NEC Class 2 requirements. Up to four load branches can be set directly on the front of the device or on the versions with integrated IO-Link interface. They can also be set remotely. In the case of an overload, the current is limited to ensure that the
maximum power of 100W defined for NEC Class 2 is not exceeded. The other NEC Class 2 load branches remain unaffected by the fault on the first output. The eFused series: The tripping current for each individual output
can be set via the buttons on the front panel of the device. A different characteristic curve applies in each case, depending on the set tripping current. If the tripping current is set to 4A, the output allows 1.25 times the nominal current (5A) for a two second duration and then switches off. See the diagram, right, for further details. The eFused power supplies
have an integrated selectivity function which allows prioritised protection of sensitive loads. Output 1 of the four-channel eFused device FPT300.246-042-101 has the highest priority, output 4 the lowest. Therefore, a sensitive, safety or system critical load, such as a PLC, is best supplied via output 1. If the overall current is exceeded, the supply switches off the outputs with the lowest priority first. Activation of the outputs is also staggered and are switched on in 100ms increments and according to their priority.
3. CONDITION MONITORING Digitalization has led to a high priority being placed on a constant central condition monitoring system. Seamless networking and communication between the various system components allows comprehensive analysis of their status and early detection of anomalies in the system. In this manner, preventative and cost-effective maintenance can be carried out. This data can also be used to see the utilisation on the current application or to make a strategic decision such as to expand the system. In both cases, the information provided by the power supply plays a key
role. The power supply is at the heart of any system and allows conclusions to be drawn about its overall operational condition. FIEPOS eFused power supplies can be easily integrated into an existing condition monitoring system, providing status data in various ways. LED interface and pushbuttons on the front panel of the device: These
allow immediate diagnostics directly in the field. At a glance a technician can see how great the load is on the power supply. The device also signals if one or more of the protected channels has tripped and can be reset via the pushbuttons on the front of the device. The tripping currents can also be configured directly at the device. Condition monitoring via IO-Link: In large-scale applications, there are
often hundreds of power supplies distributed over a wide area. In these applications, efficient preventive maintenance via a central condition monitoring system is particularly important in order to prevent costly downtimes. With the help of this information, a technician can quickly be deployed to the correct location, possibly preventing a fault from occurring. For implementation of the digital system integration of power
supplies, PULS places great value on a user-friendly and flexible solution. However, the communication interface should not affect the core functions and high reliability of the power supply. Based on these criteria, PULS uses IO-Link technology (IEC 61131-9). IO-Link is a global, standardised, communication interface suitable for
industrial use with serial bidirectional, point-to-point communication between an IO-Link device and the IO-Link Master. Simple, unshielded cables are all that is required for the wiring between an IO-Link device and the IO-Link Master. The IO-Link Master allows integration into any

4. SUMMARY A power supply solution based on the flexible FIEPOS product family is a decisive step on the road to comprehensive decentralization and allows the highest degree of flexibility in system planning. PULS is currently expanding the FIEPOS product family in order to offer all
customers a suitable, decentralized, standard power solution from stock. PULS

commonly used fieldbus or IIoT protocol such as PROFINET, EthernetIP, EtherCAT or OPC-UA. In this manner, the power supply can communicate directly with a PLC or an IIoT gateway via the IO-Link Master.
IO Device Description (IODD) A key advantage of the IO-Link interface is the low number of additional components required in the power supply. The MTBF (Mean Time Between Failures) remains virtually unchanged. FIEPOS power supplies give users access to the following information
via the IO-Link: How much output current, quality of the mains voltage, temperature, and if the load on the supply is static or dynamic. This information allows users to detect abnormally high transient surges in the mains supply, which can not only damage the power supply, but also adversely affect all other connected components. With the eFused models, it will also detect, via the IO-Link, which current- limited output has tripped and it is possible to reset the channels remotely. All this information can be analysed in a
central condition monitoring system, allowing effective preventative maintenance and increasing the system reliability while cutting maintenance and operating costs.
Output-OK signalling contact As an alternative to the IO-Link, the eFused power supplies in the FIEPOS product family are also available with an Output-OK interface, which can be selected as a
simplified alternative to the IO-Link. Its functions are similar to the established DC-ok signal of an industrial power supply. If the DC voltage fails, the device reports a fault via a common signalling contact in addition to the LED display on the front panel of the device. However, the cause of the fault can only be diagnosed by a technician
on-site. The channels can also only be reset on the front panel of the device. An M12 connection is provided on the underside of the power supply for the Output-OK signal, as well as for the IO-Link.
