Control unit HE 5721

12 valve outputs 24 V DC / max. 1 A Option: up to 24 valve outputs 2 relay outputs 250 V AC / 5 A (option) Time- / ΔP-mode (with pause time) Operational- / error display of all valves Mains supply 100 – 240 V AC, 30 VA (option: 24 V DC) Post-cleaning cycles 1-12 Valve monitoring with pressure switch (option) ΔP-Controller (Option) ΔP-measuring ranges between 0 .. 25 or 0 .. 500 mbar 3-digit multi functional display 1 relay ΔP-alarm 250 V AC / 5 A Analog output 0(4)-20 mA on the base board The solenoid valve controller HE 5721 is used to pulse solenoid valves in industrial dust extraction technology. The controller realises numerous control and monitoring functions and optionally can be equipped with ΔP-measurement and control. The cleaning takes place time-controlled or ΔP-dependent (with optional ΔP-controller) with switching thresholds or pause control. The valves are monitored for excess current (short-circuit) and interruption. Optionally, mechanical valve function monitoring can be carried out with a pressure switch. The device is suitable for use in explosion zone 22.
