GPRS gateway for remote control outputs and monitoring
• 4 digital and 2 analogue inputs; 4 digital outputs
• Mobile communication via 2G
• Mains powered and pre-wired system in waterproof boxes (IP68)
• Remote communication to control systems

KTC 300 is a pre-wired GPRS remote control station. It offers data transmission for all loop-powered 4...20 mA measuring instruments via a powered mobile modem. In addition, four digital inputs and outputs enable the operator to transmit additional digital information from the system and to switch four digital outputs remotely. For safe transmission of data an ODP protocol is used (transmission with time stamp). Integration of the protocol in SCADA systems is done via OPC DA. As an option, a private APN and a hardware firewall can be set up for increased IT security.

Product highlights
• With GPRS messaging system for remote control of outputs
• Data transmission either online or as historical values with time stamp
• Worldwide communication, any network size
• Alarm generation on voltage failure via SMS
• Communication via ODP protocol
• Configuration via USB and web browser
• Available as ATEX approved version for use in hazardous areas

Typical applications
• Data transmission for flow, level, pressure, and temperature measurement or process analysis at remote measuring points, e.g.:
• Wireless data transmission in district metering applications with water meter (WATERFLUX)
• Wireless data transmission of measurement values (e.g. level and distance) in combination with level transmitters (e.g. OPTIWAVE 5200)
