Jumo 60003411 Frost protection thermostat
Its impact-resistant housing made from high quality plastic makes the 1-pole mechanical body thermostat with relay output signal very robust and can also be used under harsh conditions. The measuring system used can be used without any problem up to a maximum admissible sensor temperature of 110 °C. The sensor line of the thermostat is made of copper. Under consideration of a bending radius of 20 mm the cable can be laid flexibly as required. The maximum permissible ambient temperature on the casing is 55 °C. For the device to work properly, the ambient temperature on the casing must be above the set switching point. The case is attached directly to the lower part of the housing as a wall mounting. The desired cut-off temperature is set by buttons and displayed in two digits on a 7-segment display. The thermostat is characterized by a high switching point accuracy of + / -1 K. The device has a potential-free relay output designed as a changeover contact. The minimum switching power is AC/DC 12 V, 100 mA, the maximum switching power is AC 230 V, 6(2) A or DC 24 V, 6 A Furthermore, the device has analog outputs that have a permissible cable length of 300 m at 1.5 mm² a current of max. 1 mA at DC 0 to 10 V. The analog input has a permissible current of max. 1 mA, DC 0 to 10 V. The voltage supply is AC 24 V. The frost monitor can be used very flexibly and is used both in building automation as well as in heating, air-conditioning and ventilation technologyThis text is machine translated.
