SCK-C-MODBUS-10PCS — package of 10 communication modules for PV installation monitoring
Phoenix Contact SCK-C-MODBUS-10PCS 1084335 is a package containing 10 SOLARCHECK system communication modules designed for collecting and transmitting measurement data from photovoltaic installations.
Each SCK-C-MODBUS module can support up to 8 SCK measurement modules, creating a central communication point for monitoring PV string voltage and current.
Data is made available via the RS-485 with Modbus RTU protocol, enabling integration of the SOLARCHECK system with a supervisory monitoring system, PLC controller or other device supporting the Modbus RTU standard.
Up to 8 measurement modules, Modbus RTU and power from one point
8 SCK modules
One communication module can collect data from up to eight connected measurement modules.
Modbus RTU
The standard RS-485 interface facilitates data transmission to industrial monitoring systems.
10 units
Part number 1084335 is the SCK-C-MODBUS-10PCS variant comprising ten communication modules.
Communication and monitoring of photovoltaic systems
Central communication module for SCK measurement devices
The SCK-C-MODBUS serves as a communication module in the modular Phoenix Contact SOLARCHECK.
Up to 8 SCK measurement modules.
can be connected to one communication module. In this way, the system can collect current and voltage data in a photovoltaic installation and transmit it onward via Modbus RTU.
RS-485 for integration with a higher-level system
Data from measurement modules is made available via RS-485 interface with Modbus RTU protocol.
Available transmission speeds are 9,6 / 14,4 / 19,2 / 38,4 kbit/s.
The maximum communication-bus length can be 1200 m, allowing the solution to be used also in extensive photovoltaic installations.
2- or 3-wire connection
The Modbus RTU interface can operate in a 2- or 3-wire.
configuration. The communication connection is made via a screw terminal block.
A terminating resistor is provided for bus termination 180 Ω. The resistor is not included with the module.
The communication module powers connected measurement devices
One of the SOLARCHECK system functions is the ability to power connected measurement modules directly from the communication module.
This reduces the number of additional power-supply components required in the PV installation junction box.
The maximum current consumption specified for the communication module is 800 mA, taking into account the ability to power connected devices.
24 V DC power supply
The nominal supply voltage of the SCK-C-MODBUS is 24 V DC with −10% / +25% tolerance.
The permissible operating voltage range is from 21,6 to 30 V DC.
Typical self-consumption of the module is 22 mA and maximum 45 mA. Power consumption at 24 V DC is approximately 580 mW.
Surge-protection and temperature monitoring
The SCK-C-MODBUS has a digital input enabling monitoring of remote signaling contacts of surge-protection modules.
This makes it possible to transmit to the supervisory system not only string measurement values but also information about the status of protective components.
The system also provides internal temperature monitoring of the measurement module, expanding the installation's diagnostic capabilities.
Built-in surge protection
The module power-supply circuit has an integrated protection system including surge protection and a 33 V suppressor diode.
The pollution degree specified for the device is 2.
The design complies, among other things, with EN 61010-1 and EN 61010-2-30 requirements.
Screw terminals for conductors up to 2,5 mm²
Electrical and communication connections are made using screw terminals.
Solid and flexible conductors with cross-section from 0.2 to 2.5 mm².
The recommended tightening torque is 0,5 to 0,6 Nm.
Operation at temperatures from −20 to +70°C
Compact 22,5 mm DIN-rail module
A single communication module is only 22,5 mmwide, so it takes up little space in a junction box or distribution board.
The dimensions of a single SCK-C-MODBUS are 22,5 × 102 × 106 mm.
The device can be mounted on a standard 35 mm DIN rail either vertically or horizontally. The mounting position is unrestricted.
22,5 mm
The narrow housing reduces the space required in the distribution board.
DIN 35
The standard mounting method simplifies integration with other equipment.
IP20
The module is intended for installation in a suitably protected cabinet or enclosure.
Design for industrial PV systems
The SCK-C-MODBUS meets the requirements of EN 61010-1 and EN 61010-2-30.
Electromagnetic immunity complies with EN 61000-6-2, while interference emission complies with EN 61000-6-4.
The product bears CE marking and UL approvals, including UL 1741 Recognized and UL 508 Listed.
