The new intelligent power supplies directly in the field

Sponsored Content

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 decentralized power supply. This means that large distances can be realized with a higher voltage, which requires smaller currents for the same amount of power, leading to lower losses. Moreover, the IO-Link-capable onsite 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.

Robust IP65/IP67 housing for installation without control cabinet
A robust IP65/IP67 housing ensures protection against electrical and mechanical hazards. Moreover, the integrated surge protection eliminates the need for external circuit protection.

Supply and output connectors in accordance with industry standards

The supply of sensors and actuators via a single cable enables a separately protected current distribution with less loss both for sensors (Us) as well as for actuators (Ua), or simply two supplies to be split by means of a T splitter.

Supply diagnostics and load display on the device
A 12-segment LED bar graph displays the current demand of the overall system as well as the current demand of each channel as a percentage of the protection configured for each single output circuit.

Configurable voltage and electronic circuit breakers for each supply channel
For every output circuit, the integrated output protection with pre-alarm and usage diagnostics can be configured in real time. The integrated circuit breakers protect your system against overload and short circuits and can each be separately configured between 1 and 12 amps.

Allowance for the voltage drop
To ensure that sufficiently high voltages are provided where they are needed, the cable resistance can be taken into account when configuring the system. The operating voltage of the system can be set in the configuration menu to values between 24 and 28 V. Calculation of the voltage drop for any system installed is recommended.
