Mã sản phẩm: BWY-804, BWY (WTYK)-804A
First, the product is a new generation product developed on the basis of BWY-802/803 thermostat. It is suitable for oil temperature measurement and control of large power transformers. It has four or six groups and can be in the full scale range. Freely set large-capacity temperature-controlled switches for cooling system startup, shutdown and output alarm signals.
A (TH) type can output one Pt100 platinum resistance signal;
AA (TH) type can output two Pt100 platinum resistance signals;
J (TH) type can output one (4 ~ 20) mA current signal;
JJ (TH) type can output two (4 ~ 20) mA current signals;
The AJ (TH) type simultaneously outputs one Pt100 platinum resistance signal and (4-20) mA current signal.
