Connector Amplifier For Proportional Valves
(4-20mA Input, DIN 43650 Coil Mount, Economy Version)

The economy version of the Connector Amplifier simplifies control of proportional solenoids by supplying a current proportional to an input control(4-20 mA). It accepts power supply voltages from 9 to 32 VDC. This linear solenoid controller utilizes high frequency switching output (PWM) to provide a DC current output. Maximum current output is 2 Amps. A current sensing circuit maintains current output regardless of changes in input voltage or coil resistance. The user can adjust maximum and minimum current. Dither frequency and amplitude are factory set to 250 Hz. In this economy version of the connector amplifier there are no ramps. The unit is available with a DIN 43650 connection to mount directly on the coil and comes complete with 2 meters of unterminated cable.

Features: Mates to a DIN 43650 plug on a cartridge or block style solenoid valve Broad range of supply voltages (9 to 32 VDC) with no degradation in performance Current sensing circuit maintains output regardless of changes in input voltage or coil resistance Modern technology utilizing high frequency switching output (PWM) IP65 weather resistance rating Energy efficient design (no heat sink is required) Short circuit proof (in case of solenoid failure or mis-wiring) Reverse polarity protection CE certified Other Connector Amplifiers
