DDD / DDU
Universal electronic Δp – two-step controller with 2 relay outputs and 4 analogue outputs 0-10 V, 2-10 V, 0-20 mA and 4-20 mA. Universal supply voltages: 110-120 VAC, 230-240 VAC and 24 VDC.
Examples: Ventilation and air-conditioning units, clean room technology, filter control, fill level control and regulation, flow detection system, etc.
For air-related applications with the ever-present turbulences, the adjustable Δp-damping of the switching points, the analogue outputs and the display is a necessary, functional advantage.
