COUNTIS ECix are multi-utility pulse concentrators communicating via an RS485 link on the MODBUS protocol. They collect and store pulses coming from water, gas, compressed air and electricity meters or, in the case of the COUNTIS ECi3 device, manage information from analogue sensors (e.g. brightness, temperature, wind). All the data, i.e. totalising and partial meters, power curves (for all TOR and analogue inputs) can be centralised via the RS485 MODBUS protocol link.
