       The MobilSwitch-5c GSM device is developed for industrial signaling and remote controlling purposes. The analog input of the device can measure between 15V or 30V, the pulse-counter input can count up to 199’999. The device is equipped with 4 digital inputs which can be connected to several modules, for instance small panels with voltageless input contacts, voltage level comparators, opto-couplers or panels that can be activated by AC voltage. The device has 4 high-voltage relay outputs which can be used for switching mains voltages. With the included software the module can be programmed with PC-s and laptops. The user get messages about the input changes via user-defined SMS-s. The outputs can be controlled by user-programmed SMS-s and by free voice calls based on caller ID. The device can be programmed for 8 telephone numbers; therefore it can send SMS-s up to 8 different numbers. The module can operate as a stand-alone GSM dialer, GSM controller or remote controller; and it can be used for remotely monitoring and controlling industrial machines, equipment and devices.

       The supply voltage level of the device is within the range of industry standards (10-30V) and it draws maximum 500mA current. The device is equipped with a unique name and identifier. All of the inputs (4+2+1) can be labeled up to 16-character long names. The SMS notifications sent by the device contain these labels, moreover the output on/off commands can be also defined by the user. The output relays can be programmed to be either monostable (i.e. after switching the output on, it will be automatically switched off after a defined time duration) or bistable (switching the output on and off requires separate commands). In monostable output mode, the outputs can be switched via voice calls and the switched-on state of the outputs can be configured up to 9999 seconds (~3 hours) of duration. As the configured time elapsed, the relays will be switched off automatically and the outputs return to their default states. For each telephone number, the user can select and configure which input changes can generate alerts and notifications for the corresponding number that can be contacted via SMS and/or voice calls. The device can be equipped either with smaller, rectangular dual-band stick antenna or with magnetic, screwable external antenna equipped with RG174 SMA-connector.

      The MobilSwitch-5c signaling and remote control module can operate on any provider's network with a microSIM card (either works with subscription or with pre-paid card) which is not protected with PIN code. After switching on the device, it searches and registers for its provider's cellular network and initializes its configuration parameters which can be downloaded into the device memory with the provided configurator software. The device keeps its configuration state and values after shutdown, including input names, output states, etc.; and it continues its operation after power-on. The MobilSwitch-5c variant is equipped with a DIN-rail compatible enclosure with unlocked GSM module, and delivered with internal Li-Po battery, GSM antenna and the configurator software. The module also can be ordered with external magnetic antenna. This module variant is the flagship device of the MobilSwitch family, however the simplified MobilSwitch-5d and MobilSwitch-5ad devices with less inputs and features and without internal battery can also be purchased.     

      The colorful LEDs located beneath the front cover indicate the status of the device. The lower, bi-color LED labeled as “Hbit” can express statuses and messages explained below, and the upper, yellow LED labeled as “SMS” indicates the SMS and voice. A “Test” button and a red jumper are located on the top of the device. When the jumper is connected, the device operates from the internal battery which is located at the bottom of the device. During power-outage, the internal battery can provide 6-8 hours of continuous operation. The battery is connected to the panel with a white-colored connector. The wiring of the panel is explained in the connection figure. The power supply voltage should be connected to the rightmost red socket located on the lower part of the panel. The supply voltage have to be between 10-30V DC, and the supply must tolerate 500mA of current draw.

      The mini-USB connector that is used for configuration is located on the bottom-left side of the panel. The microSIM card must be inserted into the holder as explained in the corresponding figure. The high-voltage high current “No-Com-Nc” type relays are located on the top of the panel and the loads connected to the relays must not draw more than 8A current at 230V. There are terminals for each pin of the relays. The GSM modem has an external SMA connector, thus not only the rectangular stick antenna, but also the external magnetic-bottom antenna with coax cord can be connected, therefore the device can be placed inside of a metal case or in a metal house of controller and the antenna can be placed outside to achieve better signal strength.

       The 4 digital inputs, the analog input and the input of the counter are located at the bottom of the panel. The digital inputs can be either voltageless type inputs, comparator type inputs that can be adjusted between 3-40V DC, opto-coupled inputs or analog inputs that sense 5-30V AC. The types of the inputs are defined by the small panels connected with pin headers to the terminals. The pulse-counter input can be either pulse-triggered or opto-coupled. The counter can count up to 199’999 and it resets in the case of an alarm. The analog input can sense voltage levels between 0-30V DC. The simple voltageless input can be triggered by 0V, i.e. by pulling the input to GND (ground) via conductors or semi-conductors. The AC sensing, opto-coupled inputs heavily delayed, since this input is used for sensing the outage of power supply. Because of the EMC and line filtering, the sensing and delay takes about 12 seconds of time. On the upper board is a "Test" button. Pushing that button the module can send a report SMS with the status of inputs and outputs. The red jumper in "On" position can connect the Li-Po battery.
       The MobilSwitch-5c module can be programmed via USB with the included software. After connecting the device to the power source, it should be connected to the PC via USB. The device driver must be installed first, therefore the operating system (Windows XP, 7, 8) can recognize the connected module. The software can configure all members of the MobilSwitch family. After connecting the device, launching the software and pressing the “Connect Device” button, the software will automatically search and recognize the connected device.

       After successful recognition, the corresponding picture of the device will be displayed inthe main window of the software. The status of the device can be queried by pressing the “Get Status” button if the device is connected to a network. The user settings can be performed by filling the appropriate input fields. With the checkboxes located next to the phone numbers, the user can specify which input alert or alerts should be sent to the telephone number via SMS. It can also be set with the Output Control columns which output should be triggered when there is an incoming phone call originated from the given phone number to the device. On the “Digital Inputs” tab, the labels of inputs and the corresponding messages that are sent via SMS in the case of input change can be set. The settings and values of the analog and counter inputs can be set on the “Analog Inputs” tab. The range of the analog input can be selected (0-15V or 0-30V), and the minimum and maximum values can be set. The pulse counter issues an alert when the counter reaches the given maximum value. On the “Outputs” tab, the output commands can be specified. These commands are sent to the device via SMS and after reception, the device will switch the output states accordingly.

       With the software, the configuration data can be downloaded into and read from the device. During downloading and reading operations, the user can track the progress with the progress-bar displayed in the pop-up window. The current configuration can be saved to a file for further validation, and these files can be opened with the software. All of the configuration data can be remotely modified also with SMS commands.The acknowledgement SMS contains the modified parameter.
