?product description
?
MDSC344E series thermal resistance temperature isolator,loop power supply,is rail-mounted,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
Receives on-site 3-wire Pt100,Cu50,Cu100,Pt50or other types ofthermal resistance signals,and after linearization processing,converts them into a 2-wire current signal output that is linear with temperature. The output loop is powered and does not require an independent working power supply. The graduation number and temperature range can be set online. Optional 1 in and 1 out.
