Case - Mounting
Case - Mounting
The SCADA Central Station must be installed by qualified personnel in accordance with local regulations (NF C 15-100 in France,
NEC in the U.S., etc.)
The case must be installed in a fire-resistant enclosure. This enclosure must stay closed during normal operation; it is only accessible
by qualified personnel and requires a key or tool to open it. The case is mounted on a standard metal DIN rail (35 mm).
The DIN rail is required to be connected to Ground; the grounding connection is carried out automatically when the case is mounted.
To remove the case from the DIN rail, the user will use a screwdriver-type tool.
If the fasteners become unfastened, the user must make sure to replace them to prevent the case from
tipping (this note also applies to each I/O expansion module).

Case – Power supply
Case – Power supply
The Compact case provides power for itself, as well for the COM modules (including the RDRTU-2 modem connected to the RS485
module) (
∗
). The entire unit is compatible with a 24 VDC (± 20%) supply voltage and is protected against reverse polarity. The 24 VDC
power supply must be TBTS/ES1.
Power connector
For the power supply, use a 0,75 mm² cross-sectional
∅
minimum.
5A fuse: Installation of a fuse is recommended on the Battery input.

–or Battery Ground
•

If there is no 24 VDC source in the electrical control panel, it is necessary to use a "24 VDC" converter box
According to the RTU hardware configuration, 2 references are available (refer to the power balance table):
•
40 W (60°C MAX)
•
90 W (70°C MAX)
The device's isolating mechanism is the ‘24 VDC + backup battery’ power connector.
Switch the case and the I/O modules off before removing or adding COM modules.
Powering the I/O modules
The I/O modules have a separate 24 Vdc power supply, independent of the compact case: it is not backed up by the battery.
Simply connect a single I/O module to a 24 VDC power source (according to the power balance); this power source automatically
propagates to other installed modules.
The device's isolating mechanism is the ‘24 VDC’ power connector.
Switch the case off before removing or adding I/O modules.
Backup battery
The power supply to the case can be backed up with a 12 VDC lead battery, either 4 Ah or 12 Ah.
A periodic battery capacity test is performed automatically. The RTU manages the charge and performs continuous self-testing
of the external battery:
•Protection against overloads
•Automatic shut-off in the event of a short-circuit
•Protection against reverse polarity.
•Battery detection.
•Protection against deep discharges (threshold at 10.2 V).
When powering via backup battery, the voltage must be at least 12 V ±200 mV to start up;
When the product has started, its operating range is between 10.2 V and 13.8 V. Furthermore, when the RTU
power supply is voluntarily cut off for a long period (typically 48 hours or more), it is necessary to disconnect
the battery to prevent deep discharge and premature wear.
Powering via solar panels
24V solar panel controllers are connected directly to the GND and +24 VDC terminals.
Use of SunSaver controllers is recommended: contact our technical
sales department to ensure selection of the appropriate controller
type (6, 10 or 20) and sizing of the solar panel according to the
geographic location of installation. Make sure to follow the
recommended installation indicated in the manual provided with
the controller: assembly in vertical position, execution of the
connections in ascending order of the terminal strips 1to 6on the
diagram opposite (battery, solar panel, then the RTU last), position of
the jumper for the use of an open battery, etc.

Example for 2 DIs:
Technical specifications
- Number of digital inputs: 16
- Contact type: Dry self-powered contact: Normally open/ closed
(configurable positioning logic)
- Maximum length of cable: 1,000 metres (AWG24 SYT+ cable type)
It is necessary to relay the digital inputs if the cable length is any higher
or if the cable crosses an environment with high interference.
- Digital input filtering: Any steady state digital input can be used for the counter acquisition;
the minimum duration of the steady state is 2 ms (max frequency = 250 Hz)
- Isolation: The DIs are isolated from the rest of the electronics; the isolation voltage
is 3000 VDC minimum. The DIs are not isolated from each other.

Case - Inputs/Outputs
Connection of AIs (4-20mA)
Only sensors with floating output delivering a current source free from any reference with respect to Ground and, in all cases, several
sources having no common point between them, are directly compatible with our materials.
Otherwise, the installer must provide a galvanic isolation device in the ‘RTU – Sensor’ link.
Installation of surge arresters:
All SOFREL sensors come with inbuilt surge protection. However, if the ‘RTU –
Sensor’ link cable runs
outside of building or extends a significant length (> 200 metres), a 4-20 mA surge arrester should
be installed on the RTU side.
Example for 2 AIs, ‘4-20 mA’:
Technical specifications
- Number of ANA inputs: 4 in measuring current 4-20 mA
- Type: - Precision: 0.1% (25°C)
- Resolution: 16 bits
- Remote power feeding: - 2 sensors per remote power feed
- Voltage = 16V ±10 %
- Protection current = 50 mA (maximum for 1 or 2 inputs)
- Input impedance: - 100 Ω

Case - Inputs/Outputs
Connection of DOs
DOs are 12 V / 24 V AC/DC ’very low voltage’ voltage-relay type digital outputs: they are compatible with 24 V relays and control panel
indicator lights.
By default, and following a total power cut (24V and Battery), DOs are in their 'open' state (idle state = 0).
In case of product reinitialisation, the state of each DO is retained (no forced return to the idle state).
The user defines the ‘bistable’ or ‘impulse’ control type when configuring each DO data point.
When a DO is configured to control the ‘Watchdog safety’ feature; this output is reinitialised according to inverse logic (the output is
in the closed state if no default; it switches to the open state if a default is present). This 'Watchdog' output is very useful for controlling
power supply and for the proper functioning of the RTU (see § ‘Data processing – Operational safety’).
The DO do not allow direct control of power units.
Example of control of 2 DC relays by 2 DO:
Technical specifications
- Number of DO: - 4 in alternating current (AC) and/or direct current (DC)
- Output type: - free from all potential
- Maximum switching voltage: - 24 V AC/DC +20% (40 V peak)
- Continuous current: - 150 mA
- Isolation: - 1500 VRMS between the DO and the control case

Case - GSM Connection
Case - GSM Connection
The compact case comes standard with a 2G/3G-compatible GSM modem: the RTU thereby communicates in GSM-IP with its
recipients (SCADA Central Station, Inter-RTU with other remote units, PC S4W-Tools, Email recipient) and in SMS.
Operation Communications Frequency Bands (in MHz)
- 3G UMTS/HSDPA B1 = 2100, B2 = 1900, B5 = 850, B6 = 800, B8 = 900, B19 = 800
- 2G GSM/GPRS/EDGE B3 = 1800, B5 = 850, B8 = 900, B25 = 1900
The 2G/3G modem does not provide any insulation; the antenna must therefore be put inside the building where the S4W is installed.
Otherwise, make sure to use an appropriate isolation device.
The GSM external antenna is the ‘Penta-band’ type (2G/3G compatible).
The SMA female connector is used to connect the ’0 dB’ ¼-wave GSM antenna.
(Tightening torque: 0.4 Nm max).
Make sure the RTU is switched off before inserting the SIM card.
Accessing the micro SIM card
Inserting and removing the micro SIM card is done on the left side of the case, by pressing on the bottom of the connector with
the contacts facing the rear of the case, until there is a locking click.
To insert the micro SIM card, open the flap on the left side of the case: this action does not require removing any
communication modules or disconnecting any I/O cables.
The bracket allows the antenna to be mounted
vertically on a metal ground plane: This metal
plane is necessary only when a ¼-wave GSM
antenna is used.
