The SIMATIC RTU3000C is a compact module in SIMATIC S7-1200 format:

• Rugged, compact plastic enclosure for the temperature range -40 °C to +70 °C
• Easily accessible connection and diagnostics elements
• Easy mounting on a standard DIN rail
• Four plug-in screw terminals for eight digital inputs (pushbutton/switch/relay contacts) of which the first two inputs can be configured as counter inputs.
• Four plug-in screw terminals for four analog inputs: Current / voltage (0/4…20 mA, 0…10 V, 0…5 V) or temperature measurement (Pt1000)
• Two plug-in screw terminals for four digital outputs designed as relay contacts
• The close-loop (12 V or 24 V can be selected) and switchable controller outputs X10/X11 can be used for the supply of sensors and actuators
• 5-pin, plug-in terminal strip for connection of an 12 ... 24 V DC external supply voltage; connection protected against polarity reversal
• Connection socket for battery module (up to six battery modules can be connected)
• RJ45 socket for connection to Industrial Ethernet at 10/100 Mbps
• Pushbutton for the functions wake-up, shutdown, warm restart or reset to factory settings
• Slot for an SD card (Siemens SMC, SD or SDHC)
• Installed temperature sensor for monitoring of temperature inside enclosure

Additionally for RTU3030C:

• SMA antenna connection for GSM/GPRS/UMTS antenna
• Slot for a mini SIM card

The telecontrol stations of the RTU3000C family can be used in stand-alone operation. The power supply can take place in independent operation by means of battery / accumulator /solar panel. The optional batteries are connected directly on the left side of the device without additional wiring. The power can also be supplied by a 5-pin terminal strip on the bottom of the module, even in combination with battery modules. The SD card tray is located on the front of the module. Removable screw terminals make for quick module replacement because the connected sensors must not be wired again.
