Worldwide system/machine remote monitoring and alarm

Industrial modems RS-232 (V.24) / Analog (V.34)RS-232 (V.24) / GSM/GPRS

The GSM modem PSI-GSM/GPRS-MODEM/RS232 and the V.34 modem PSI-DATA/FAXMODEM/RS232 have been specially tailored to the industrial requirements of remote maintenance and alarm messaging.

GSM modem

The DIN rail mountable GSM modem PSI-GSM/GPRS-MODEM/RS232 allows global access to machines and systems via GSM or GPRS connections. Comprehensive safety functions, e.g. presettable, selective call acceptance, password protection and call-back function prevent unauthorized access.

Of particular value for remote system monitoring are the configurable warning or fault warning inputs. If they are activated, the modem dials up a predefined number and sends the saved text messages as fax, SMS or e-mail, or sets the output of the device at the opposite end. The switching output can also be set with a password protected SMS.

To guarantee interference-free operation even under difficult EMC conditions, the device has high-grade galvanic isolation and integrated surge protection. The universal features of the modem are complemented by the automatic battery-saving "sleep" function and the particularly wide range of supply voltages from 10 to 60 V. Startup is simple with Plug&Play and convenient configuration software. The modem can be operated in all 900 and 1800 MHz GSM networks.

Analog modem

The V.34 modem PSI DATA/FAX-MODEM/RS232 has proven itself for global use and has the same comprehensive functions as the new GSM modem. Here too, the focus is on EMC, electrical isolation, and surge protection for safe operation. It is also possible to send fax, SMS or e-mail via a switching output.

This modem is approved for operation in the public telephone networks in Europe, USA and Canada. Further certifications are currently in preparation. These modems have been tested with the most common PLCs from various manufacturers and industrial PCs in numerous applications for remote maintenance.
