Product description
Three-phase energy meter with built-in configuration key-pad; particularly indicated for the metering and the management of the energy in addition to the metering and the management of the signals coming from the water and gas meters. Housing for DIN-rail or wallmounting, IP40 (front) protection degree. Completely sealable housing. In case of direct connection up to 90A, the measuring input terminals are suitable for cables with a cross-section area from 6 to 35 mm2. The special design of the instrument's housing allows to add at any time the interface modules, even when the instrument is already installed. The following modules are available: - for all versions: pulse output; - only for the versions with auxiliary power supply: digital inputs, RS485 serial port.

Only open collector outputs: the grounds of the outputs are separated, and therefore it's possible to carry out, for the same module, two different connections. The load resistance (Rc) must be designed so that the closed contact current is lower than 100mA; the VDC voltage must be lower than or equal to 30V. VDC: power supply voltage output.
