The cheap programmable controller BTC38 is designed for wide range of ON/OFF control applications. Equipped with a 3-digit LED display, BTC38 is especially suitable for measuring and controlling various technological values with resolution of up to 1000 points. It can be ordered in various cases including the smallest 1/32 DIN case, and for different power supplies. The device has 1 programmable relay control/alarm output and is available in 2 universal-input versions: RTD – for 7 selectable Ptx and 4 Cux sensor types, and T/C – for 3 selectable thermocouples as well as versions for linear current and voltage signals. RT38 allows an automatic software compensation of line resistance and cold junction temperature. The display-to-input correspondence (in case of linear input), the decimal point position, the temperature measuring unit as well as the offset value are also programmable. Thanks to its power supply options, semi-universal input, and excellent price-to-performance ratio, BTC38 is an exceptionally widely applicable device.
