Asco
Control unit for POSIFLOW solenoid valve Proportional electronic control unit for POSIFLOW solenoid valve.Converts analogue input control signals of a solenoid by means of pulse width modulation.Valve closure function at less than 2% of the maximum control signal.Adjustable ramp control.Coil supply current is independent of coil resistance (temperature) and supply voltage variations.Coil supply current can be adjusted based on control signals.Electronic circuit is integrated in a unit that can be connected to a 3-terminal coil. Technical characteristics Supply voltage 24V ±10% (UN), with 10% residual ripple. Maximum current 1100 mA Input control signal Uc: 0 → 10 V Icx: 0 → 20 mA Ic: 4 → 20 mA Control unit ambient temperature range -10 → +75 °C Switch-off current Ramp duration Selectable On - Off, can be adjusted from 0.1 → 3 s Sealed: IP 65 Standards ISO 4400 / EN 175301-803, form A / IEC 335. Two Way Inert Gases and Fluid Valves Compact solenoid valves suitable for most gas and fluid handling applications. Where practical, valves are shown with a schematic diagram showing the (circuit) function. The diagram is laid out so that the left-hand side of the diagram describes the valves operation when the coil is energised. When the coil is de-energised, the spring (or servo-assist) return controls the valve and is described on the right-hand side of the diagram. The 3 / 2-way designation indicates a valve with three ports and two modes of operation. It is normal practice to refer to 2 / 2-way valves as two ways. The port designations A, B, P, P1, P2 and R are used on the schematic diagrams and are marked on the valve bodies. Valve bodies are marked for a specific circuit function but can often be used for other functions. Reference to the schematic diagrams and technical specifications indicates the appropriate connections and pressure capabilities when an alternative circuit function is required. ; For Use With Proportional solenoid valve; Series E908; Supply Voltage 24 Vdc;
