Chapter 1: Getting Started
The SG2 PLR is an electronic device. For safety reasons, please carefully read and follow the
paragraphs with "WARNING" or "CAUTION" symbols.They are important safety precautions to be aware
of while transporting, installing, operating, or examining the SG2 Controller.
WARNING: Personal injury may result from improper operation.
CAUTION: The SG2 PLR may be damaged by improper operation.
Precaution for Installation
Compliance with the installation instructions and the user manual is absolutely necessary. Failure to comply could
lead to improper operation, equipment damage or in extreme cases even death, serious bodily injury or considerable
damage to property.
When installing the open-board models, insure that no wiring or foreign materials can fall into the exposed circuits
and components. Damage to equipment, fire, or considerable damage to property could result.
Always switch off power before you wire, connect, install, or remove any module.
The wiring for the SG2 PLR is open and exposed. For the open-board models, all electrical components are exposed.
For this reason, it is recommended the SG2 PLR be installed in an enclosure or cabinet to prevent accidental
contact or exposure to the electrical circuits and components.
Never install the product in an environment beyond the limits specified in this user manual such as high temperature,
humidity, dust, corrosive gas, vibration, etc.
Precaution for Wiring
Improper wiring and installation could lead to death, serious bodily injury or considerable damage to property.
The SG2 PLR should only be installed and wired by properly experienced and certified personnel.
Make sure the wiring of the SG2 PLR meets all applicable regulations and codes including local and national standards
and codes.
Be sure to properly size cables for the required current rating.
Always separate AC wiring, DC wiring with high-frequency switching cycles, and low-voltage signal wiring.
Precaution for Operation
To insure safety with the application of the SG2 PLR, complete functional and safety testing must be conducted.
Only run the SG2 after all testing and confirming safe and proper operation is complete. Any potential faults in the
application should be included in the testing. Failure to do so could lead to improper operation, equipment damage
or in extreme cases even Death, serious bodily injury or considerable damage to property.
When the power is on, never contact the terminals, exposed conductors or electrical components. Failure to comply
could lead to improper operation, equipment damage or in extreme cases even death, serious bodily injury or
considerable damage to property.
It is strongly recommended to add safety protection such as an emergency stop and external interlock circuit in case the
SG2 PLR operation must be shut down immediately.

Examination Before Installation
Every SG2 PLR has been fully tested and examined before shipment. Please carry out the following
examination procedures after unpacking your SG2 Programmable Logic Relay.
• Check to see if the model number of the SG2 matches the model number that you ordered.
• Check to see whether any damage occurred to the SG2 during shipment. Do not connect the SG2 PLR to the power
supply if there is any sign of damage.
Contact FactoryMation if you find any abnormal conditions as mentioned above.
Environmental Precautions
The installation site of the SG2 PLR is very important. It relates directly to the functionality and the life
span of your SG2 .Please carefully choose an installation site that meets the following requirements:
• Mount the unit vertically
• Environment temperature: 32°F - 131°F (0°C - 55°C)
• Avoid placing SG2 close to any heating equipment
• Avoid dripping water, condensation, or humid environment
• Avoid direct sunlight
• Avoid oil, grease, and gas
• Avoid contact with corrosive gases and liquids
• Prevent foreign dust, flecks, or metal scraps from contacting the SG2 PLR
• Avoid electric-magnetic interference (soldering or power machinery)
• Avoid excessive vibration; if vibration cannot be avoided, an anti-rattle mounting device should be installed to reduce
vibration.

General Specifications
SG2 is a miniature smart PLR (Programmable Logic Relay) with a maximum of 44 I/O points and can
be programmed in Relay Ladder Logic or FBD (Function Block Diagram) program. The SG2 can
expand to its maximum I/O count by adding 3 groups of 4-input X 4-output modules.
