The EL9501 power supply terminal generates an adjustable output voltage from the 24 V DC input voltage. This makes it suitable for supplying sensors or devices that require less than the 24 V that are usually available. It can also be used like an analog output terminal to simulate slowly varying signals but has far more output power than a 20 mA channel. The operating status is output via LED and process data. The diagnostics include the output current and the output voltage, so it is possible to integrate the terminal into an external control loop – for example, to reduce load effects.

The terminal is part of the group of adjustable supply devices. If no adjustable output is required, fixed voltage devices or power supplies are available.
