LoRa Modbus Analog
I/O Controller
LM100/LC100 Series
The LM100/LC100 series utilizes the latest Low Power Wide Area
(LPWA) technology to build Modbus/RTU communication for long-
distance, wide-coverage, and low power consumption wireless IoT
applications.
Multiple analog inputs and outputs are supported in LC100 series,
such as voltage inputs and outputs, current inputs and outputs,
PWM output and one RS-485 port for Modbus RTU slave. One
LM100 RS485 Modbus RTU can connect up to 250pcs LC100 LoRa
end nodes for two-way communications where field site analog
signals are sent from LC100 and controlled by LM100. The LoRa
wireless distance can reach up to 3-6KM distance depending on the
environment.
The LM100/LC100 series offers great flexibility in wireless IoT
applications, such as LED light control, environment sensors and
meters reading for Smart City Applications such as Lighting, Smart
Farming, Smart Environment Monitor, etc.

Wiring the Grounding
The earth ground is located on the
top side of the rdevice. For
avoiding system damage by noise
or electric shock, establish a direct
connection between the ground
screw and the groundingsurface
prior to connecting devices.

DIN Rail mount
To mount the router on the DIN Rail
track, insert the upper end of the
DIN‐Rail clip into the back of the
DIN‐Rail track from its upper side
and lightly push the bottom of the
DIN‐Rail clip into the track. The DIN
Rail should comply with DIN
EN50022 standard. Using wrong
DIN rail may cause unsafe
installation.
Wiring the Power Input (10~30V)
1) Insert the positive and negative wires into the
V+ and Com contact on the terminal block
connector. V-/COM is a share negative pole.
2) Tighten screws when the wire is connected.
3) Connect the power wires to suitable DC
Switching type power supply.
