The CTH summing amplifier / summation transducer is used to sum four analog signals to one summation output. Usually anything from 2-4 analog signals are applied to the sum inputs, these can be 4-20mA current loop signals or three voltage signals, the summation output can be a 4-20mA current loop signal or 0-10V. Optional custom inputs/outputs are available. A typical application is where a power or current summation is required from various three phase incomers/feeders, possibly at different locations within a plant, meaning that one analog signal can represent the total plant consumption whether kW, kVAr, kVA or even MW
The CTH summing amplifier / summation transducer is used typically with voltage, current, energy or power sensing transmitters/transducers. It can be configured to operate with most transmitters, sensors, transducers and data loggers. Custom inputs and output are possible, making scaling straightforward.
The CTH summation module is used where the summation of several transducer signals is required. Example: summing several 4-20mA kW output signals from power transducers situated at different locations within a plant, the CTH summation module will provide one sum signal equal to the total kW
