Description
Meter in tight (IP 67), wall mounting case, with current-voltage input, 2 relay (or OC type) outputs and 1 analogue output, according to the customer selection: active current output, passive isolated current output or active voltage output. The meter may be configured with no need to open the case, by using the remote controller or with free Config software via the RS-485 communication port. The device operates in the following modes: linear, root, square and user defined (max. 20 points).
