DTA Motor thermistor relay Benefits High operating safety. The thresholds are determined by the Motor PTC. Beyond the specified temperature the output stops the motor/s. Save time and costs. There is no need to connect other additional and expensive controllers. Ensure continuous production process in your plant. This type of controller allows limitation of false alarms which may be the cause of useless interruptions of production systems. One or two outputs. It is possible to select the 1 or 2 outputs version. The 2 ouputs version provides, besides interrupting the the Motor supply, the addition signal for a lamp, PC or PLC. Low profile DIN rail mounting. These devices can be mounted on classic din rail in a cabinets or in a electrical Description panel, The 60mm height allows installation in many applications. Bi-colour front LED. These devices indicate alarms for DTA71 and DTA72 are precise Motor thermistor temperature and PTC. monitoring relays. They can monitor up to 6 motor temperatures through the motor internal temperature. PTCs are connected in series when multiple motors are monitored. DTA71 features 1 output, AUTO reset and no TEST switch. DTA72 features, besides the 2 outputs, the TEST switch and the local or remote manual RESET. It can also be configured as AUTO. The bi-colour front LED, through colours and blinks, indicates Power ON, PTC failures, alarms and when it is ready for RESET. Applications This product is extremely suitable for pumps monitoring. It can be useful in all applications where motors are used especially where overloads are frequent and may cause motor damages: pumping stations, water treatment, conveyors, material handling, HVAC, chillers. etc. 08/07/2016 DTA72 DS ENG Carlo GAvazzi Automation S.p.A. 1 DTA72 Monitor thermistor relay Main features Reset input for remote pushbutton. 35mm low profile DIN enclosure.
