The CTHsum summing amplifier / summation transducer is used to sum voltage, current, energy or power sensing transmitters / transducers. It can be configured to operate with most transducers/transmitters and data loggers. Custom isolated inputs and outputs are possible, making scaling straightforward.

The CTHsum summing amplifier / summation transducer is used to sum up to 4 analog signals to one summation output. Typically 2-4 analog signals are applied to the sum inputs, these can be a combination 4-20mA current loop signals or voltage signals, the summation output can be a 4-20mA or 4-12-20mA current loop signal or 0-10V bipolar. 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 CTHsum summing amplifier / summation transducer is also used to sum voltages, currents from pressure, energy or power sensing transmitters/transducers. The summation inputs can be configured to operate with most transducers/transmitters and data loggers. Custom isolated inputs and outputs are possible to avoid ground loop interaction between.
Used to sum up to four 5V, 10V or 4-20mA analog signals to one output 4-20mA or 0-10Vdc. The CTHsum summation module is used where the summation of several transducer signals is required. Example: summing several 4-20mA kW (delete kW) output signals from temperature or power transducers situated at different locations within a plant, the CTHsum summation module will provide one sum signal output, equal to the total of the inputs
