Energy Management Systems

Product Details:

DTA02C115 precise thermistor monitoring relays. They can be used to monitor the temperature of the coils of a motor with built-in PTC’s. The alarm status of the relay can be reset by either an external contact or an internal button (DTA02, PTA02). The test button allows the simulation of the fault condition (DTA02, PTA02). The red LED indicates the alarm status.

Features:

• Motor temperature monitoring relay
• Measuring ranges: PTC according to EN 44081 
• Remote and local alarm reset (DTA02, PTA02)
• Output: 8 A SPDT (PTA01/DTA01/DTA02) or SPST (DTA01) relay, normally energized 
• For mounting on DIN-rail in accordance with DIN/EN 50 022 (DTA01, DTA02) or plug-in module (PTA01, PTA02)
• 22.5 mm Euronorm housing (DTA01, DTA02) or 36 mm plug-in module (PTA01, PTA02)
• LED indication for relay and power supply ON (DTA02, PTA02)
• Galvanically separated power supply.

Product Details:

VMU-C EM is a modular system that records, monitors and transmits analog and digital signals from an industrial, commercial or residential installation with a specific focus on energy efficiency. The system includes a web server with a powerful and intuitive user interface to monitor data and set up the system. Data can be transmitted using various protocols (FTP, HTTP, Modbus TCP/IP) and via wired or wireless connection.

Benefits:

• Integrated system. The system is a package of integrated modules. The main module includes the web server with a web interface to monitor and set up the system.
• Integrated Software. No subscriptions or additional services are required.
• Fast, easy and free updates. Integrated software updates can be easily downloaded and installed via web interface, without losing data and without additional fees.
• Communication flexibility. The system transmits data (to CARLO GAVAZZI's or third party systems) via various communication protocols (FTP, HTTP, Modbus TCP/IP).
• Scalability. The system can be progressively integrated with new modules according to application needs. 
• Fast installation and set-up. The entire system is installed and set up via web interface.
• Reliability. The system is secure against cyber attacks and computer viruses. Data redundancy and backup tools prevent information losses.
• High monitoring capacity. The system manages up to 100 meters, analog and digital inputs.
• High recording capacity. The system records data and events for a system for up to 30 years.
• Compact size. The maximum module package dimension is 8-DIN. Note: max number of energy meters depends on the meter type; check the table "VMU accessory modules and meters".
• IoT Ready. VMU-C EM is "Microsoft Azure Certified for IoT".
