● For DC units the external 24 V DC supply must be generated and supplied
according to the requirements for safe extra-low voltage (SELV) since this
voltage is provided near the operating elements and at the terminals for the
supply of sensors without further protection measures�
3 Documentation
This documentation relates to the hardware and firmware status at the time of
editing this manual� The features of the devices are continuously developed further
and improved�
4 Functions and features
The devices have been designed for use in applications described in this manual
and the device-specific data sheets�
Adhere to the data indicated in the data sheets and in the manual� If the handling
specifications and safety instructions for configuration, installation and operation
indicated in the documentation are adhered to, the devices normally do not lead to
a danger for persons and objects�
5 Sensor functions
The diagnostic electronics has
– 2 analogue inputs
– 4 dynamic inputs
– 1 analogue or digital output
– 1 digital output
– 1 TCP/IP parameter setting interface
– 2 Modbus TCP ports
An analogue current signal (0/4…20 mA) or a pulse signal (HTL) can be
connected to the analogue inputs�
The analogue inputs can be used
– as trigger for measurements (e�g� rotational speed for vibration diagnostics)
– as trigger of a counter
– for process monitoring
VSA, VSP or standard IEPE acceleration sensors can be connected to the
dynamic inputs�
