CTH summation - Summation transducer
The CTH summation transducer is used to sum three kW analog signals into one kW output. Usually three signals (to a max of 6) are applied to the sum input, these can be mA current loop signals or three voltage signals, the output can be transmitted as a 4-20mA current loop or voltage. A typical application is where a power summation is required from various three phase feeders, possibly at different locations within a plant, this means that one analog signal can represent the total plant kW or MW.
