With the GSM-PRO2 series CONTA-CLIP offers a 4G telecontrol and remote maintenance solution to monitor and control decentralized systems or plants. The GSM-PRO2(E) module informs the user when the process has reached a certain status or limit. Digital and/or analog input values are transmitted via SMS or e-mail. For a decentralized control room or for the responsible service technician there is the possibility to switch the digital relay outputs via SMS. In this way, the process can be monitored and controlled decentrally. Monitoring and control of the GSMPRO2(E) module is greatly simplified by the available iPhone and Android apps. Parameterization of the module’s inputs and outputs and their desired functions is done via an easy-to-understand application.
