1. Preface
Thank you for choosing Ursalink UC1122 LoRa Remote I/O. This user guide will present in detail
all the functions and features of the product. Ursalink UC1122 is designed for both industrial and
commercial applications. The product should be used under the guidance of this user guide,
referring to parameters and technical specifications. The UC1122 is a compact, high-performance
device that offers LoRaWAN connectivity for remote access and easy management of machines
and equipment over the cellular network.
We bear no liability for property loss or physically injury arising from abnormal or incorrect usage
of this product.
2. Introduction
Ursalink UC1122 is designed as a cost-effective industrial machine monitoring device that
monitors and controls up to 1 DC signal, 1 drivable relay output and 2 analog inputs.
With the aid of Ursalink UC1122, the alarm condition brings attention to engineering personnel
immediately. The output can be connected with an alarm indication device, such as a light or
horn.
The module can give immediate response to the status of both the input and output conditions.
A LoRa module is embedded in the Ursalink UC1122 .
This user guide is intended to provide detailed technical specifications and explanations to the
basic user as well as the technically-minded groups. It is a live document, and will be updated
from time to time. Please ensure that you have the latest version, by checking our website at:

3. Installation
3.1 Environment
Due to the product properties of Ursalink UC1122, we STRONGLY advise that it should not be
installed in proximity to a variable speed drive or with any other electrically noisy equipment. DO
NOT install the Ursalink UC1122 into a metal enclosure unless an antenna is mounted on the
outside of the enclosure.
3.2 Power Supply
The Ursalink UC1122 features a 2 pin 3.5mm terminal block where a power supply can be
connected. The power supply should have the following specifications:
Output Voltage: 12V nominal
Output Current: 0.5A
Installation:
A suitable power supply comes with the retail product.
For industrial applications, it is advised that the Ursalink UC1122 should be installed into its own
metal housing and be powered from a separate power supply (as opposed to sharing one with
other equipment).
Please Note: While the Ursalink UC1122 has fairly rugged internal power supply circuitry, no
special provision for lightning protection is well in place. If the Ursalink UC1122 is used in an area
where thunderstorm is about to occur, it is advisable to use a commercially available lightning
suppressor (the same applies to inputs or outputs that are connected to wires longer than 2 or 3
meters). The guarantee does not cover damage resulting from lightning strikes! The Ursalink
UC1122 can operate reliably from voltages in the range of 5 to 24 VDC.

Terminal
Description
VIN
Positive terminal of the DC power supply (+)
GND
Negative terminal of the DC power supply (-)
3.3 Micro USB Port
The Ursalink UC1122 provides a micro USB port to connect to a PC via USB cable, which allows
the PC to configure the unit.
3.4 Terminal Description
1 [DC 5-24V]
2 [Analog Input]
4-20 mA
3 [Digital Input]
Opto-isolated depending on voltage DC Voltage (3-24V)
4 [Digital Output]
Driving relay to connect NC or NO
3.5 Analog Input
When the value of analog input exceeds or is under the predefined threshold, the Ursalink
UC1122 will take action by pre-configured related command.
Input current: 4-20mA
UC1122 User Guide

Maximum Current
3 Amp
Maximum Voltage
250VAC, 30VDC
3.6 Digital Input
When the input is triggered either as high or low, the Ursalink UC1122 will take action if you
have pre-configured related commands.
Terminal "IN" is internally pulled high. Leaving the connection open or connecting it to "0 -1
V"will indicate an "Input-De-activate" state.
When terminal "IN" is connected to "3-24 V", it will indicate an "Input-Activate" state.
Trigger voltage: Minimum = 3 VDC, Maximum = 24 VDC.
3.7 Relay Output
The output is used for switch circuits ON & OFF and can be controlled by command message
The output terminals are internally connected to a 3 Amp SPDT relay
OUT_NC = Normally Closed
OUT_COM = Common
OUT_NO = Normally Open
