WP501 Capillary Sheath LED Temperature Switch Controller

Short Description:

WP501 Switch Controller is a intelligent large aluminum terminal box combined with intelligent LED indicator and 2-relay alarm switch. The component is compatible with universal input of common process variable, including thermocouple and resistance thermometer. The circuit board can output standard transmitter analog output (4~20mA) as well as upper & lower limit switch quantity output. Within the measuring range, upper and lower alarm threshold value can be adjusted continuously.
