| Technical specification | 3-way temperature relay for Pt 100, Pt 1000, KTY 83/84 and PTC sensors. Type TR250 temperature relays monitor up to 3 sensors simultaneously for up to 3 limit values. Different types of sensors, e.g. PTC conductor and Pt 100, can also be connected and evaluated. Applications include monitoring motors, generators or transformers. The device is also suitable for use as a 2 or 3-point controller with additional over/low temperature alarms, as a differential temperature monitor and as a temperature controller, e.g. for heat pumps. Measurement and monitoring range -199... +850 °C Resolution 0.1 °C programmable in the range -19.9... 99.9 °C 3 relay outputs AC/DC 24-240 V all-voltage power supply Easy programming with 3 buttons Storage of minimum and maximum values of the sensors Alarm memory for 3 x 99 alarms with display of the sensor and the elapsed time. Code lock against unintentional/unauthorized changes to settings.
