?product description
?
The MDSC304E series thermal resistance temperature isolatoris rail-mounted,and the base and the host can be separated and plugged in,making installation and maintenance easy. The series of products is rich in variety and handle various industrial signals such as current,voltage,thermal resistance,thermocouples,and switches. The products are widelyused in various industries such as building materials,metallurgy,and electric power to effectively suppress various interference signals.
??
Function
Receive on-site 3-wire Pt100,Cu50,Cu100,Pt50or other types ofthermal resistance signals,and after linearization processing,convert them into voltage or current signal output that is linear with temperature. Optional: 1 in,1 out,1 in,2 out. The graduation number and temperature range can be set online.
