Contrel elettronica CTT-4 Temperature Monitor setara TECSYSTEM T154

The CTT-4 model engineered by Contrel, is a temperature monitoring relay that features a programmable thermal control unit to an extent..
Description

Programmable thermal control unit up to 8 inputs from Rtd Pt100 sensors.- Programmable alarm, trip and ventilation threshold on each input- It shows the parameters and measures on 2 ample digital displays, added function of maximum values memory, it displays automatically the highest temp- Extendend range of power supply 20 - 250 Vcc/cc or 110 - 230 - 400 Vca- Serial output RS232/RS485 Modbus Rtu with management software- Analog output 0/4 ÷ 20 mA measures conversionFUNCTIONSThe control unit programmed through keys located on the front panel:- Election of the number of active channel- Ventilation control- Alarm and trip temperatures (hold function)- Storage of alarm abd trip conditions APPLICATIONSOvertemperatures caused by overloads or internal failure due to degradetion of the dielectric qualities of insulating materials in transformers and electrical machines, inevitably leads to a reduced efficiency andenergy loss in ditribution systems. To prevent and control degradation ofinsultaing materials in electrical machines due the thermal stress, it sinecessary to use integrated measurement systems such as CTT control units.




Model CTT-4 yang direkayasa oleh Contrel, adalah relai pemantauan suhu yang menampilkan unit kontrol termal yang dapat diprogram hingga 4 input dari sensor Rtd Pt100. Pada setiap input dilengkapi alarm built-in, trip dan ventilasi. Selain itu, ia memiliki peningkatan rentang catu daya 20 ÷ 250 Vcc/cc atau 110 - 230 - 400 Vca. Peralatan ini menyoroti spesifikasi dan perhitungan pada 2 tampilan digital yang luas. Selain itu, keluaran analog 0/4 ÷ 20 mA menghitung konversi.
