I/O Board for SMS Alarm & Control

The I/O board when used in conjunction with the ETM 9560-1 or ETM9900-1 Modem allows for the connection of typical commercial/industrial sensors and control components such as;
 - 0-10v or 4-20mA sensors

 - Switching of DC loads to a maximum of 2A 30VDC

The modem can then perform alarm, control and/or data aquisition functions either via SMS or IP (GPRS/UMTS) connection. The two modem options offer 2G GSM/GPRS (ETM9560-1) or 3G/NextG (ETM9900-1) connectivity.

Typical applications include;

 - Irrigation pump control

- Alarm and control of air conditioning & refrigeration units

 - Remote monitoring water or fuel tank levels

 - Remote monitoring of environmental conditions such as temperature, humidity, rainfall etc
