CCM Single-phase meter with RS-485

CcM4 is one of the devices from the CcM product family designed to measure electrical parameters (voltage, current, energy, harmonics distortion, etc.) in three-phase installations with a neutral wire. The CcM product range consists of a set of devices used for the monitoring of electrical parameters inside the electrical switchboard in single- and three-phase installations. It is best suitable for installation in thermal-magnetic switches or residual-current circuit breakers. CcM4 is one of the “principals” CcM product family devices (CcM4, CcM3 and CcM2). Their function is two-fold. To work as a slave of the general master (PLC or PC, Windows/Linux, o directly with the CcMaster) inside the principal bus and as a master inside the secondary bus, commanding other devices of the CcM family – CcM1-C and CcM3-C secondary devices. The user can access the data from CcM4 through RS-485 communication cable, using Modbus RTU protocol or through one of the free software tools offered, such as CcManager (configuration, viewing and storing in a local network) or the clicMONITOR webpage (viewing and storing data in the cloud). It is also possible to add CcM WiFi peripheral to obtain data through a WiFi network and analyse the data using the clicMONITOR App and the Scada Web (scada.clicmonitor.com).

As it can be combined and used with different devices within the product range, the CcM product family offers multiple configuration options and allows users to configure the most convenient solution for both, their domestic and industrial installations. Installations can be wireless, connected with a communication cable or mixed. The devices can be connected to each other and create communication buses, establishing configurable master-slave hierarchies. CcM4, for instance, behaves similarly to an energy meter or a grid analyzer. Inserted directly into a thermal-magnetic switch or a residual-current circuit breaker, the device is connected in series with the consumption line, registering voltage, intensity, power, active and reactive energy as well as harmonics in each of the phases.
