The MD200 data logger is designed to record measured values and display them in the graphic, backlit LC display. The device is equipped with either 1, 4 or 8 temperature or current inputs. The internal data memory of 2MB is sufficient for approx. 0.5 million data records (8MB as variant with USB host port). If a USB stick is connected, the recording time can be extended as desired without the need for data transfer to the PC. A digital signal input enables the triggering of the recording process. The device also has two freely configurable switching outputs. An individual alphanumeric description is available for each channel. The multilingual menu, supported by text descriptions, makes the configuration process very easy. The transmitter supply enables the supply of connected transmitters. The RS-485 interface allows the device to be connected to the process control system.
