FCD3245-01 model data logger is a four-channel data logger (three temperature inputs and one humidity input) and is designed to send temperature information of power plant sites to the electricity market system. This data logger also has the possibility of sending data using four current output channels of 4~20 mA in order to record and observe the temperatures in the DCS of the power plant. With the possibility of remote OTA update, this data logger has the ability to update and adapt to possible changes in the protocol announced by the electricity market system. The three-and-a-half-inch display installed on the data logger displays the input data (along with the necessary mappings) in real time, as well as the sending status and the responses received from the system.
