R-SG3 Analog I-O Modules
Product Information: R-SG3 and R-SG3-P Installation Manual
The R-SG3 and R-SG3-P are modules that are used to transmit and
receive signals through RS485, Ethernet, and Profinet
communication. These modules are designed for qualified
electricians and are sensitive to electrostatic discharges. The
product comes with a user manual that should be read before any
operation. The module must be repaired and damaged parts replaced
by the manufacturer.
Preliminary Warnings
The word WARNING preceded by the symbol indicates conditions or
actions that put the user’s safety at risk. The word ATTENTION
preceded by the symbol indicates conditions or actions that could
damage the instrument or connected equipment. The warranty shall
become null and void in the event of improper use or tampering with
the module or devices supplied by the manufacturer as necessary for
its correct operation, and if the instructions contained in this
manual are not followed.

Module Layout and Technical Specifications
The R-SG3 module has dimensions of 53.3mm x 90mm x 32.2mm and
weighs 80g. The case is made of self-extinguishing UL94-V0 PC/ABS
material. The R-SG3-P has additional LED signals on the front
panel. The module has certifications for insulation, Ethernet
communication, RS485 communication, analog input, communication
power supply, and digital I/O. The maximum working voltage between
any terminal and ground must be less than 50 Vac / 75Vdc. The
module should be stored in a temperature-controlled environment
with a protection rating of IEC EN60715, 35mm DIN rail in vertical
position.
Usage Instructions
- Read the user manual before any operation.
- Use the module only if you are a qualified electrician.
- Take appropriate measures to prevent electrostatic discharges
during any operation. - Do not tamper with the module or devices supplied by the
manufacturer as necessary for its correct operation. - Contact the manufacturer for repair or replacement of damaged
parts. - Dispose of the product at a collection center authorized to
recycle electrical and electronic waste.

ModBUS CONNECTION RULES
1) Install the modules in the DIN rail (120 max) 2) Connect the remote modules using cables of an appropriate length. The following table shows cable length data: – Bus length: maximum length of the Modbus network according to the Baud Rate. This is the length of the cables that connect
the two farthest modules (see Diagram 1). – Derivation length: maximum length of a derivation 2 m (see Diagram 1).
For maximum performance, it is recommended to use special shielded cables, such as BELDEN 9841.
ETHERNET CONNECTION STANDARDS
Per il cablaggio Ethernet fra i dispositivi è previsto l’uso del cavo CAT5 o CAT5e non schermato; CAT6 per ambienti industriali.
FACTORY IP ADDRESS (R-SG3 ONLY)
The module’s default IP address is static: 192. 168. 90. 101
WEB SERVER
Use the following credentials to access the Maintenance Web Server: Default user: admin Default password: admin
CAUTION
DO NOT USE DEVICES WITH THE SAME IP ADDRESS IN THE SAME ETHERNET NETWORK.
SETTING THE SW1 DIP-SWITCHES:
WARNING
The DIP-switch settings are read only at boot time. At each change, perform a restart.
For operation and settings via DIP-SWITCH see the user manual available on the product webpage.

PS BUTTON1
The tare is reset using the PS1 button. To reset the tare it is necessary to hold down the PS1 button for three seconds. The update of the value can be viewed via Webserver or ModBUS.
ELECTRICAL CONNECTIONS
CAUTION
The upper power supply limits must not be exceeded, as this could cause serious damage to the module. Switch the module off before connecting inputs and outputs. To meet the electromagnetic immunity requirements: · use shielded signal cables; · connect the shield to a preferential instrumentation earth system; · separate shielded cables from other cables used for power installations (inverters, motors, induction ovens, etc…).
