1. Refer to this manual before the first use
2. Make sure that all cables are connected properly before the first use
3. Please ensure proper working conditions, according to the device specifications
(e.g., supply voltage, temperature, maximum power consumption)
4. Turn the power supply off before making any modifications to wiring connections.
2. Module features
2.1. Purpose and description of the module
SFAR-S-16DO Module is an innovative device that provides a simple and cost-effective
extension of the number of outputs in popular PLCs.
The module has 16 Digital Outputs. All inputs and outputs are isolated from the logic of using
optocouplers.
This module is connected to the RS485 bus with twisted-pair wire. Communication is via
MODBUS RTU or MODBUS ASCII. The use of 32-bit ARM core processor provides fast
processing and quick communication. The baud rate is configurable from 2400 to 115200.
The module is designed for mounting on a DIN rail in accordance with DIN EN 5002.
The module is equipped with a set of LEDs to indicate the status of outputs which is useful
for diagnostic purposes and helping to find errors.
Module configuration is done via USB by using a dedicated computer program. You can also
change the parameters using the ModBus protocol.

2.3. Dimensions of the product
The appearance and dimensions of the module are shown below. The module is mounted
directly to the rail in the DIN industry standard. Power connectors, communication and IOs
are at the bottom and top of the module. USB connector configuration and indicators are
located on the front of the module.
3. Configurating of the communication
3.1. Grounding and shielding
In most cases, IO modules will be installed in an enclosure along with other devices which
generate electromagnetic radiation. Examples of these devices are relays and contactors,
transformers, motor controllers etc. This electromagnetic radiation can induce electrical
noise into both power and signal lines, as well as direct radiation into the module causing
negative effects on the system. Appropriate grounding, shielding and other protective steps
should be taken at the installation stage to prevent these effects. These protective steps
include control cabinet grounding, module grounding, cable shield grounding, protective
elements for electromagnetic switching devices, correct wiring as well as consideration of
cable types and their cross sections.

SFAR-S-16DO User Manual
Version 3.0 www.gc5.pl Page 7/ 16
3.2. Network termination
Transmission line effects often represent the problem of data communication networks.
These problems include reflections and signal attenuation.
To eliminate the presence of reflections at the end of the cable, the cable must be terminated
at both ends with a resistor across the line equal to its characteristic impedance. Both ends
must be terminated since the direction of propagation is bi-directional. In the case of RS485
twisted pair cable this termination is typically 120 Ω.
3.3. Setting Module Address in RS485 Modbus Network
The following table shows how to set switch to determine the address of the module. The
module address is set with the switches in the range of 0 to 31. Addresses from 32 to 255
can be set via RS485 or USB.

3.5.4. Watchdog information
This 16-bits register specifies the time in milliseconds to watchdog reset. If module does not
receive any valid message within that time, all Digital and Analog Outputs will be set to the
default state.
This feature is useful if there is an interruption in data transmission and for security reasons.
Output states must be set to the appropriate state in order to reassure the safety of persons
or property.
The default value is 0 milliseconds which means the watchdog function is disabled.

5.3. Quick connect
Quick Connect is an unique feature of modules that allows you to quickly connect group of
devices with a flat ribbon cable. Thanks to this solution, it is enough to connect power and
RS485 communication to one of the devices in the group and the others will be powered and
communicated with ribbon cable.
The Quick Connect is sufficient to connect up to 10 devices next to each other. What is
important that the various types of modules in the SFAR-S family can be connected with the
ribbon cable.

8. Configuration software
Modbus Configurator is the type of software which is designed to set the communication
module registers over Modbus network as well as to read and write the current value of other
registers of the module. It’s a convenient way to test the system as well as to observe real-
time changes in the registers.
Communication with the module happens via the USB cable. The module does not require
any drivers.
Configurator is a universal software, whereby it is possible to configure all available modules.
