CTH analog summation transducer for 0-10V or 4-20mA signals
The CTH summation transducer is used to sum three analog signals to one summation output. Usually three 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. 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 as kVA, kW or MW.
The CTH summation transducer is used typically with voltage, current or power sensing transmitters/transducers. It can be configured to operate with nearly all transmitters, sensors, transducers and data loggers. Custom inputs and output are possible, making scaling straightforward.
CTH analog summation module
Used to sum three kW analog signals into one kW output
The CTH summation module is used where the sum of several transducers is required. Example: summing several analog 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
