The second generation I/O board from ETM Pacific is for use with 2G/GSM and 3G/NextG Intelligent terminals. It allows the connection of typical commercial/industrial sensors and control components, such as 0-10 V or 4-20 mA sensors and switching DC loads to a maximum of 2 A at 30 VDC, to ETM9570-1 or ETM9910-1 intelligent terminals to allow for SMS alarm and/or control applications or automated data logging.
The board builds on the flexibility and success of the existing unit by adding an optional 24 V switched sensor power supply, while itself being powered at any voltage in the range 6-35 VDC.
Two versions of the board are available, one without switched sensor supply and one with.
