The IoT Kit provides a practical, all-in-one solution for networked processes in a compact tabletop size. Its use of open-source software and the availability of source data enable easy customization and do-it-yourself projects. The different services run on the Raspberry PI such as an Apache Webserver / PHP Server (Website with shopping cart) and a MySQLServer (Database). The components use a Siemens Scalance 5-port switch to communicate with each other’s and a tablet preconfigured with the DC Wattmeter App. Possible uses with: – EduKit PA – MPS PA Compact Workstation – MPS PA Bottling Station – EDS Water Management (Water Supply Station) Scope of delivery – Raspberry Pi 4 Wireless LAN – Top-hat rail housing – Power supply, – SD Card with – Raspbian operating system Services – MySQL-Server (Database) – Siemens Scalance 5-Port Switch – Adapter for connecting Tablet to Ethernet via cable – 7-inch tablet preconfigured with DC Wattmeter App – Network cable set Order no. 8162599 2 Water-Air Cooler – Aluminum heat exchanger with copper line and flexible plug-in fittings – 2x 24 V dc axial fans with 0 – 10 V adjustable speed input and encoder speed feedback – Profile foot for mounting – Connecting cable for I/O connection board – 1x digital output, optional: – 1x analog input 0 – 10 V Order no. 8080632 3 Cooling Unit with Heat Exchanger Hermetically sealed refrigerant circuit that is air-cooled with an axial fan that can be added to a MPS PA station for faster cooling. The heat exchanger is made of non-ferrous metal and has one 3/4” filling port as well as two 1/4” threaded female connections. Suitable for continuous operation and does not require any maintenance. The heat exchanger builds into the circulation pipe for tank-to-tank process with pump. Separated media circles: cooling and heating. Manual control of the cooling circuit by a temperature controller and a 2-way valve. Technical data: – Temperature range -10 °C to +40 °C – Ambient temperature +12 °C to +30 °C – Cooling capacity at +30 °C: 380 W – Control accuracy +/- 1 K – 4 liter/min 0,15 bar max. pressure – Coolant tank volume: 4 Liter, filling port 3/4”, inlet/outlet: 1/4” – Refrigerant R134a – Dimensions 260 x 370 x 405 mm (width x length x depth) 220 – 240 V, 50/60 Hz 8164444 120 V, 60 Hz 8162598 4 Trolley Through-holes enable orderly routing of cables. The front side is equipped with mountings for panels. – Height (including casters): 750 mm – Width: 700 mm – Depth: 700 mm Order no. 8106686 5 DC Wattmeter The DC wattmeter is a smart meter for training facilities with a 24 V DC power supply and up to 120 W power consumption. All measured values can be read out via data transmission with the integrated Ethernet port. Power consumption is read out as an analog signal within a range of either 0 to 10 V DC.
