5.3.34 Optional expansion board
Depending on the package, TFortis PSW outdoor switches can be equipped
with an additional expansion board that increases the functionality of the device.
At the moment, TFortis switches can be equipped with one of the following two
versions of the board:
PLC-01
and
PLC-02
.
PLC-01
expansion board has the following interfaces:
2 relay outputs (250V, 10A)
1 RS485 output to connect to power metering devices.
PLC-02
expansion board has the following interfaces:
3 dry contact inputs
1 relay output (250V, 100mA)
1 RS485 output to connect to power metering devices.
5.3.34.1 Digital inputs
Special Function → Inputs/Outputs
Depending on the expansion board model, it can be equipped with dry contact
digital inputs. The inputs can be used to connect various sensors to detect a short
circuit or an opening, for example, a tamper sensor, a motion sensor, etc.
For each input, you can configure an alarm condition, in which a message will
be sent to the server.
Figure 5.3.34.1 Configuring inputs
Enable
