WP501 Series Intelligent Switch Controller

Short Description:

WP501 Intelligent Controller features a big round aluminium casing terminal box with 4-digit LED Indicator and 2-relay providing ceiling & floor alarm signal. The terminal box is compatible with sensor component of other WangYuan transmitter products and can be used for pressure, level and temperature control. H & L alarm thresholds are adjustable over the whole measurement span in succession. Integrated signal light will up when measured value touches alarm threshold. Besides alarm signal, the switch controller can provide regular transmitter signal for PLC, DCS or secondary instrument. It also has explosion proof structure available for hazard area operation.
