4.2.1 Input Monitoring
The status of the inputs and outputs can be monitored in the relevant measurement menu.
There are 8 Digital Inputs (20-264V AC / DC) in order to adapt to all kinds of applications in
400 series protection relays. In case of use of the I/O card, 10 Inputs are added to the CPM,
VPM and DPM. Inputs are optically isolated and programmable. The display on the device is
read-only; does not allow data entry.
The following figure shows the 'Input Monitoring' of the device. If the input value on the

4.2.2 Output Relay Monitoring
There are 8 output relay with 8A / 250V AC contact capacity on the standard equipped
device. Relay trip times are less than 10 ms. Four of these relays have an inverted contact; the
other 4 are with closed contacts. All of these relays are programmable. Relay programming
can be adjusted from the Menu > Automatic Control > Output Relay Settings. The status of
the inputs and outputs can be monitored in the relevant measurement menu. The display on
the device is read-only; does not allow data entry.
