Model PSV-D Driver Modules in combination with electromagnetic control valves respond to variable signal inputs to regulate flow. Constructed of stainless steel they may be used with a wide array of fluids.
Control, is based on 4 - 20 mA or 0 - 5 Vdc analog signals. AUTO-SELECT feature recognizes input reference signal type received; defaults to 4 to 20mA if both signals are provided. Jumper selectable output power optimizes dc voltage output range as a function of flowrates for better input to output ratio.
Internally resettable fuse protects electronics; rectifier circuit prevents accidental polarity reversal damage.
