As the number of I/O and sensor components, controllers and HMIs that can be mounted in the field has surged in the last years, larger and larger parts of the overall controller architecture can be directly mounted on the machine. Until now however, the power supply equipment always needed to be safely placed in a central but often remotely located control cabinet. Disadvantage: The distribution of supply voltages as low as 24 V over large distances requires high currents in order to provide loads with the power they need. This leads to high losses and requires large conductor cross sections.
Decentrally distribute 24 volts, centrally monitor power supplies with IO-Link
ifm’s IP67 power supplies, which can be mounted directly in the field, enable decentralised power supply. This means that large distances can be realised with a higher voltage, which requires smaller currents for the same amount of power, leading to lower losses. Moreover, the IO-Link-capable on-site 24 V power supplies allow computer-aided monitoring, configuration and diagnostics. Thus, faults that need to be fixed can be solved quickly and from a central location. This leads to increased uptimes; the overall efficiency of the system goes up.
The robotics industry relies on independent on-site control systems that either work without a specific control cabinet or with one offering only limited space. Reliable power supplies suitable for industrial-grade applications ensure that the robot cells work at the highest level of efficiency; moreover, they eliminate or at least reduce the need for control cabinets; the weight and footprint of the control system as a whole are improved.
The flexibility in the configuration of electronic circuit breakers and loads enables the devices to be standardised and helps reduce overall operating costs.
The success of an intralogistics or logistics tracking system depends on how easy its configuration and set-up are. As the need for control cabinets is eliminated, tracking systems can be installed anywhere in the system with no conventional installation needed.
Regardless of whether we consider the installation of one single UHF reader for access control to closed forklift areas, gantry loading solutions for perimeter control and the tracking of reusable objects, or outdoor tracking in agriculture or mining: Quick and easy installation is crucial, and remote diagnostics and control are a necessity.
Often, vibration and temperature sensors are retrofitted to simple machines in order to help with the early detection of damage. These sensors as well as the components needed to transmit the data do not require a control cabinet. But where does the supply voltage come from? The simple answer to this question lies in the power supplies that can be mounted directly in the field.
Assembly cells are used for cost-efficient automation of routine tasks. Regarding those applications, the boundaries concerning size and performance are continuously expanded. Eliminating the need for control cabinets saves time here, both during initial equipping and during the service life of the machine, and helps increase productivity considerably over the entire service life of the cell.
The integrated electronic circuit breakers allow real-time load feedback and quick fault diagnostics, which enables the machine to be up and running again in no time – all of this without a control cabinet. Two separate output circuits in one single cable make virtually independent operation and the separation of sensors (Us) and actuators (Ua) possible with one single cable strand.
