Phoenix PSI-GPRS GSM-MODEM RS232-QB GPRS/GSM Cellular Modems

GPRS/GSM Cellular Modems

The PSI-GPRS/GSM-MODEM/RS232-QB rail-mountable modem is specifically designed to meet industrial requirements for remote monitoring and alarm generation. It provides global access to machines and systems via GSM connections. A wide range of security functions, such as adjustable, selective call acceptance, connection establishment with password protection, and call-back function, protect the system against unauthorized access. The integrated TCP/IP stack even allows the implementation of simple control systems into the GPRS network.

One particularly useful feature for remote system monitoring is the configurable warning or alarm inputs. If these inputs are activated, the modem calls user-defined numbers and sends stored text messages by fax and/or SMS. Using the switching output, additional functions can be controlled via SMS messages. To ensure error-free operation in harsh EMC conditions, the device has high-quality, 3-way isolation and integrated surge protection.

The modem also features an integrated automatic “Sleep” function to increase battery life, and a wide supply voltage range of 10 to 30 V DC, making it suitable for universal use. Modem startup is very easy using plug and play and user friendly configuration software.

The modem is approved for use in both the North American (850 and 1900 MHz) and European (900 and 1800 MHz) frequency bands. Each modem is shipped with a country specific, pre-installed SIM card, and must be registered for use through the registration portal before operation. The registration portal can be accessed at http://phoenix.diversenet.net.
