• Analog Inputs
A1 and A2 are terminals for analog signals input.
These terminals can be used for analog signals
acquired from sensors such as temperature sensors,
humidity sensors, etc for further processing. The
reference for A1 and A2 is GND. Figure 7 shows an
Analog input implementation.

• Relays
RELAY 1, RELAY 2 and RELAY 3 are three pairs of
high-voltage, high-current, single pole single throw
(SPST) relay outputs rated at 240VAC@10A or 24V
DC@10A. The SPST relay contacts are polarity-
insensitive, and they can be used to switch both AC
and DC loads. It can be used to perform on/off controls
on loads such as motors and lamps etc. as in Figure 8.
It can be configured to open the dry contacts based on
a schedule and/or when a combination of input
conditions occur, thus cutting off the power supply to
the load.. (Please contact gridComm, for future use
only).

• 4GB On-Board Extended Flash Memory
The 4GB on-board extended flash memory (optional)
is important for storage of historical data such as
power consumption, device life time, alerts and
alarms. This historical data parameters can then be
easily retrieved by the system should there be a
failure with the TCP link or the server.
• GSM/3G TCP Link
The device is built in with a GSM/GPRS module to
enable the TCP link connectivity with the server
operating the Street Light Management Software.
