ZIEHL industrie-elektronik, 74523 Schwäbisch Hall, Germany, +49 791 504-0, info@ziehl.de, www.ziehl.de Technical Data Function Measuring and monitoring range - 199...+850°C resolution 0.1 °C selectable within 3 relay outputs K1 to K3 with change-over contacts Universal power supply AC/DC 24-240 V Easy setting Storing of values of MIN- and MAX- temperature Alarm counter for 3x99 alarms with display of sensor and elapsed time. Code-lock against manipulation of settings The Pt100 thermostat TR250 monitors up to 3 sensors Pt100 (RTD), Pt1000, KTY83 KTY84 or thermistors (PTC) at the same time. Different types of sensors, e.g. Pt 100 and PTC can be mo- nitored simultaneously. The unit is especially suitable for monitoring motors, generators and transformers. An other application is the use as a 2- or 3-step-controller with additional monitoring of over- or under-temperature. monitoring of differences in temperatures of 2 sensors or temperature controller for heat pumps.
