Embodiment Construction

[0035] figure 1 Shown is a relay 100 with controllable relay contacts 102 having an electrical connection end 101 at which electrical variables can be tapped, a control connector 103 for receiving control signals, The control signal is used to start the relay contact; and the controller 105 is used to detect the zero-crossing of the electrical variable after receiving the control signal, and after the zero-crossing of the electrical variable, to bring The controllable relay contact 102 is activated in a time-delayed manner.

[0036] The electrical connection terminal 101 can be connected to a voltage supply system 107 at which the supply voltage of the relay 100 can be tapped.

[0037] The controllable relay contact 102 has control inputs A1 and A2 to which the controller 105 can actuate the relay contact 102 by applying a control signal. The controllable relay contact 102 also has a controllable switch 109 which enables electrical connection or electrical disconnection of t...

Abstract

The disclosure relates to a relay having a controller. The relay (100) has a controllable relay contact (2) and an electrical connection terminal (101) where an electrical variable is able to be tapped, a control connection (103) for receiving a control signal for actuating the relay contact (102), and a controller (105), configured, in response to the reception of the control signal, to detect azero crossing of the electrical variable and to actuate the controllable relay contact (102) in a time-delayed manner after the zero crossing of the electrical variable.

Description

technical field [0001] The invention relates to an electromechanical relay with a controller. Background technique [0002] Different types of relays are used in various applications. Typical applications in the industrial sector are the driving of electrical loads, which can be resistive, inductive or capacitive consumers. [0003] Since relays are electromechanical devices, they always exhibit their mechanical behavior during operation. Therefore, when the relay is activated, the relay contacts may briefly bounce or chatter before eventually reaching their end positions. Furthermore, during contact bounce, especially when closing the contacts at maximum voltage or opening them at maximum current, there is a risk of generating large electric or magnetic fields which, in the open state of the contacts, could further lead to mishaps. desired arc. [0004] When the energy of this arc is high enough, it can damage the contacts of the relay. In addition, the heat generated ...
