Anti-interference of time relay execution relay of blister packaging machine

When the winding (inductive load) of the executive relay is switched on and off. There will be a series of electromagnetic oscillation radiation with high rise speed and high frequency and amplitude in the coil. For DC relay windings, the following methods are usually used to reduce interference: anti-parallel diodes or RC devices at both ends of the coil, such as control contact pairs. In the control of AC inductive load, RC devices can also be considered in parallel with the contacts, so that the interference generated when the contacts are switched on and off can be effectively absorbed.
