Description

RT38-Y is a programmable ON/OFF controller, designed for direct control over temperature or other processes when coupled with a TSEC temperature probe or other sensor. The device is equipped with a 3-digit LED display and a control relay. Available are 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. The controller can be ordered either for mains or for low-voltage power supply and 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. RT38-Y is enclosed in a robust plastic box with IP66 connector and enables easy and firm sensor assembly. Thanks to its design, RT38-Y is widely applicable in cases, in which direct control of electrical actuators is required.
