The SIMATIC RTU3030C is a compact module in SIMATIC S7-1200 design:
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 terminal for eight digital inputs (pushbutton/switch/relay contacts) of which two can be configured as counter inputs
Four plug-in screw terminal 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 two battery modules can be connected)
SMA antenna connection for GSM/GPRS/UMTS antenna
RJ45 socket for connection to Industrial Ethernet at 10/100 Mbps (only local for commissioning)
Pushbutton for the functions wake-up, shutdown, warm restart or reset to factory settings
Slot for an SD card (Siemens SMC, SD or SDHC)
Slot for a SIM card
Installed temperature sensor for monitoring of temperature inside enclosure
The RTU3030C can be used as stand-alone device. The power supply can take place in independent operation by means of battery / accumulator /solar panel. The optional batteries (maximum of two modules) 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 antenna socket for the mobile radio antenna is located on the top, the SIM slot on the bottom and the SD slot on the front of the module. Removable screw-type terminals make for quick module replacement because the connected sensors must not be wired again.
