Control unit HE 5720

Activation of 12 (24) solenoid valves Valve voltage 24 V DC (1 A) Time- or ΔP-dependent controller mode Integrated ΔP-control function Function- and malfunction indication of every individual valve Valve monitoring functions (option) Power supply 230 V AC, 30 VA (option: 115 V AC or 24 V DC) 4 relay outputs 250 V AC, 5 A (malfunction, follow-up signal, ΔP-alarm, ...) The HE 5720 valve control system is used for pulse activation of solenoid valves in air pollution control systems. Basically the device has 12 outputs to activate 12 valves with 24 V DC. With an extension board the HE 5720 controls 24 valves. These functions are available: Timer mode, ΔP-dependent cleaning (part- / full cycle), forced cleaning, post cleaning, lag-time control for discharge organs, etc. The operator can select the timer mode with variable pause time or the ΔP-dependent mode based on the built-in ΔP-controller. The HE 5720 has a high-speed current check for all valves to detect open loops or short-circuits.
