The GSM-PRO2 I/O communication modules has 2 universal inputs and 1 digital relay output. The universal input can be set in analogue or digital mode. In digital mode the module can send e-mail or SMS messages and making phone calls by changes of a flank. In analogue mode the module can send e-mail or SMS messages and making phone calls when upper and lower threshold values exceed. The CONTA-SUPERVISION IoT portal/App values are shown realtime and with one finger touch a output can be operated.
Next to the universal inputs the GSM-PRO2 has a counter input. This can, for example, keep track of the number of kWh on the basis of pulses. The output relay has 2 contacts and a rated current of 10 ampere at 230V AC. The GSM-PRO2 I/O communication module uses the 4G, 3G and 2G frequency bands.
