Carlo Gavazzi Monitoring Relay | Yashima Industry
Carlo Gavazzi Monitoring Relay: Reliable Monitoring Solutions | Japan's Only Distributor: Yashima Industry
Carlo Gavazzi offers automation monitoring relays based on an easy-to-use DPD concept. This allows users to set up the units directly, accommodating a variety of needs. It can monitor various electrical parameters such as voltage, current, frequency, power factor, and phase sequence. There are three installation options available, supporting a wide range of installation environments including industrial control panels, plug-in sockets, and low-profile DIN rails. It supports diverse applications such as three-phase power, current, voltage, and temperature monitoring. In particular, the three-phase power relay can monitor phase abnormalities and voltage anomalies with a single device. Current monitoring is compatible with both AC and DC, and can handle high currents with external current transformers. Voltage monitoring supports single-phase/three-phase and AC/DC, making it suitable for battery monitoring as well. Temperature monitoring is compatible with NTC/PT100 sensors and can be utilized in industrial and building automation fields. It also features power and power factor monitoring capabilities, allowing for the detection of load fluctuations and power factor anomalies. Frequency monitoring enables high-precision measurements of three-phase systems thanks to the DPD concept. The latest DTA71/72 temperature relays are compatible with a variety of sensors and are suitable for a wide range of applications.
