Product description
Three-phase power analyzer with built-in configuration key-pad; Particularly indicated for the analysis of main, secondary and energy metering electrical variables. 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 mm . 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: pulses output; - only for the versions with auxiliary power supply: analogue output, RS485 port or alarm output.

Relay + open collector output Fig. 11
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. Vo+: positive output contact (open collector transistor). GND: ground output contact (open collector transistor). Analogue output Fig. 12 RS485 Serial output Fig. 13 RS485 Serial output Fig. 14
