Temperature data logger TCA4-1I/12-24V
T=(-99º...+650ºC), Us=12÷24V ac/dc, Pt100, 95x49x113mm
The single-channel digital temperature data logger TCA4-1I/12-24V is a microprocessor device with a 4-digit display, which serves to measure and archive temperatures in the range from -99ºC to +650ºC. The temperature data logger uses a Pt100 temperature sensor as a sensing element for measuring the temperature. The device is designed for installation in a dashboard (panel montage).
The digital single-channel temperature data logger TCA4-1I is a compact microprocessor device which is used for measuring and archiving temperatures within the range from -99º to +650ºC. The temperature data logger has one input, which is designed for operation with a 2-wire or 3-wire temperature sensor Pt100. The temperature data logger has a built-in EEPROM memory saving the recorded current temperature each minute in real time. The memory installed in the device allows storage of 8192 recordings (with an option of 16384 recordings). The temperature data logger is designed for incorporation into an industrial network, working with RS485 a standard data exchange protocol on a two-wire line. On the rear panel of the temperature data archiver a “6P4C” telephone plug is mounted through which it communicates with a computer. The transfer of data from the archiver's EEPROM memory to the computer is carried out through the use of the software "esa_net_5.00" and driver "Driver_FT232R", which are pre-installed on the computer.

Overall dimensions (mm)
The single-channel digital temperature archiver TCA4-1I is an electronic device used for measuring and archiving temperatures in the range from -99º to + 650ºC. The temperature archiver uses a Pt100 temperature sensor as a sensitive element for measuring temperature. The main purpose of the single-channel temperature archiver is to store the measured temperatures for a certain period of time.
