WTC-Wireline Telemetry Cartridge
An intelligent bridge between the tool bus and surface system collecting data from the tools
The Wireline Telemetry Cartridge (WTC) is an intelligent bridge between the tool bus and surface system.
It serves both as a communications interface and as a programmable logging controller. It collects data from the tools through the toolbus and then converts all data to packets and then sends it to the surface system, also it can receive commands from the surface system to control the working mode of the downhole tools. There is one DC-DC converter built-in to convert the high voltage from the line to a lower working voltage for the toolbus.
