1. APPLICATION
The 4-channels analog outputs module is designed
to convert numerical data to standard (voltage or current) sig-
nals, by means of the MODBUS protocol.
The output signals are divided into 2 sets of 2 outputs, which
are isolated between themselves. RS-485 and USB ports are
isolated from outputs signals and the supply. The module setting
can be done through USB or one of the RS-485 interface using
the available for free eCon program.
The S4AO module performs the following functions:
• analog output (current and / or voltage, according to the or-
dering code),
• 2 independent interfaces RS-485 Modbus. Each can be con-
figured as Slave or Master, which set to output a signal pro-
portionally to a value read from another Slave device,
• short-circuit detection on voltage outputs,
• timer counting time work over an upper threshold and bene-
ath a lower threshold,

3. BASIC REQUIREMENTS, OPERATIONAL
SAFETY
The symbols in the manual mean:
• Warning!
Warning of potentially hazardous situations.
Especially important to be aware of before
connecting the device. Failure to follow the direc-
tions marked by this symbol could result in serious
injuries of the personnel and damage of the device.
• Caution!
Useful notes. The notes should facilitate
the operation of the device. Should pay attention,
if the device is not working as expected.
Possibleconsequencesincaseofignoringin-
formation!
In terms of operational safety the meter meets the requirements
of the EN 61010-1:2011 standard.
Commentsconcerningsafety:
• Assembly and installation of the electrical connections should
be conducted only by people authorized to perform assembly
of electric devices.
• The person installing the device is responsible for ensuring
the safety of the implemented system.
• Always check the connections before turning the device on.
• Opening the device housing gives access to the live parts.
The supply must be switched off and the output circuits
disconnected before removing the device housing.
• Removal of the device housing cover during the warranty
period voids the warranty.

4. INSTALLATION
4.1. Mounting
The S4AO module can be installed in modular distribu-
tion devices on the 35 mm rail bracket.
The module enclosure is made of plastic and its dimensions are
53 x 110 x 60.5 mm.
There are pluggable terminal blocks on the outside of the mo-
dule to connect the power supply, the RS-485 port 1 and the
analog outputs signals using leads up to 2.5 mm2. The module
dimensions are shown in Figure 2.
• The device is designed to be installed and used in the indu-
strial electromagnetic environment conditions.
• The building installation should have a switch or a circuit-
-breaker installed. This switch should be located near the
device, easy accessible by the operator and suitably marked.
• In case of damage, the module can to repaired only by
manufacturer’s authorized service.
• Check the correct operation of the device after a repair. befo-
re using it for operation.
• Connection and/or using the device in a way which is not
compliant with the user’s manual, may cause deterioration
of the degree of protection.
• Maintaining a voltage output on short-cicuit state will make
an overheating of the module, and can cause troubles
on RS-485 communications.

4.2. External Connection Diagrams
The module connections are shown in Figure 3.
The polarization of the power supply is not needed when the
module is supplied by a d.c. voltage.
