The digital power meter GOBLIN is a micro-controller based unit which not only measures a host of electrical parameters to display them on a 128 x 64 backlit LCD, but also acts as a comprehensive load managing device due to its four numbers of output relay contacts. These outputs are individually field programmable for both the parameter on which to generate alarm as well as the values on which to activate alarm and deactivate it. In addition to this flexibility in terms of load management, the meter also has two serial ports: USB port and RS485. RS485 supports MODBUS RTU protocol for connections to EMS/SCADA. Goblin has two USB ports-one where a cable connection to laptop/pc is made(Device mode) and another where the unit directly accepts a pendrive(Host mode).
