2.3.6 Connection of digital input signals to terminals of type EL1002
The digital input terminals are realized with the type EL1002 providing two channels per
terminal. Internally the failure monitoring of the overvoltage protection clamp KN 1 is connected
to the clamp DI-01 (see Picture 3). External digital input signals from a process system can be
connected to the clamps DI-02, DI-03 to DI-16. These signals can be used as trigger signals
to directly start a measurement. Furthermore the digital input signals can be used as process
channels for the classification. The classification can be used as tool to have class dependent
threshold monitoring of online characteristic values of vibration acceleration signals. The
connection of digital input signals is shown in Picture 6.

2.3.7 Connection of digital output signals to terminals of type EL2004
The digital output terminals are realized with the type EL2004 providing four output channels
per terminal. In high state each channel provides an output voltage of 24 V
DC
with a maximum
current of 500 mA relative to ground. The digital output signals are connected on the clamps
labeled with DO-01, DO-02 up to DO-16. The clamp with a black - on blue ground is the
corresponding ground connection. A digital output can signalize configured characteristic value
or process factor alarms. The connection of digital output signals is shown in Picture 6.
