1. Overview
The DZS-17E delay intermediate relay is used for current circuits in relay protection and automatic devices. It serves as a return delay auxiliary relay to increase the number and capacity of contacts, and can also be used in other circuits that require delay.
2. Institutional characteristics

The working principle of DZS-17E delay intermediate relay is based on electromagnetic principle, consisting of electromagnetic system, contact group, delay circuit and other parts. The delay adopts a resistive capacitive charging and discharging circuit. When the excitation amount is input to the relay coil, the electromagnetic system generates electromagnetic force, which attracts the armature and causes the relay contacts to close or open. At the same time as the excitation amount is input to the relay coil, the capacitor in the resistance capacitance circuit is charged. When the excitation amount disappears, the resistance capacitance circuit discharges the coil, causing the relay to return with a delay.
