CTH analog summing amplifiers, 4ch summation transducers for 0-10V or 4-20mA signals

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.

CTH Summing - Summation Transducer — **CTH Summing Module**

CTH analog summing amplifier module

Used to sum up to four kW/kVA/kVAR analog signals into one output 4-20mA or 0-10Vdc

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
