Product Announcement from R. STAHL, Inc.
Houston - R. STAHL's 9719-type GSM/GPRS modem, which combines a robust design with state-of-the-art technology and easy installation, allows users to fully benefit from the advantages of GSM/GPRS data communication in zone 1 or 2 hazardous areas for the first time.
Designed as a quad-band device, the 9719 modem is suitable for use in process plants in virtually all world regions. Thanks to IP67 protection, the unit can be installed in outdoor areas without an additional enclosure. The SIM card holder and the antenna interface are intrinsically safe (Ex i), thus enabling users to safely change SIM cards or install antennas in hazardous areas. The modem is directly connected to a PLC, an Industrial PC or an OpenHMI via an RS232 interface. It comes with a wide range of functions which can be easily controlled via the same AT command set as conventional modems for standard industry applications. An LED display continuously indicates the modem status.
