Modularized communication type relay

Abstract

A modularized communication type relay disclosed by the present invention comprises a relay assembly, one side of the relay assembly is electrically connected with an input acquisition unit, an MCU processing unit, a storage unit, a power supply module, an AC / DC module and a Bluetooth module, and the power supply module is used for outputting a voltage required by an electrical structure in the device. The relay assembly comprises a recording structure assembly and a relay electrical structure, the recording structure assembly comprises a data acquisition module, an inductive load data storage module and an alarm module, and the recording structure assembly is electrically connected with the relay electrical structure, so that real-time recording and storage of excess values and times of a relay are realized; and if the maximum excess value is reached, an alarm prompt is given, so that a user can master the general use condition of each group of relays conveniently, and the block type communication relay can realize real-time detection through an internal circuit, so that the problems existing in the conversion process can be known more intuitively. Problems and whether the electrical life reaches the limit can be quickly known, and spare parts can be made in advance.

Description

technical field [0001] The invention relates to the field of relay devices, in particular to a modular communication relay. Background technique [0002] A relay is an electrical control device, which is an electrical appliance that makes a predetermined step change in the controlled quantity in the electrical output circuit when the change of the input quantity (excitation quantity) reaches the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] Electromagnetic relays are used more and more widely. When resistive loads and inductive loads are used, it is impossible to measure the ca...

AI Technical Summary

Problems solved by technology

[0003] Electromagnetic relays are used more and more widely. When resistive loads and inductive loads are used, it is impossible to prepare for measuring the load capacity, which often causes problems such as contact arcing and adhesion. The conventional energizing current of inductive loads is small, but the instantaneous current is normal. times to dozens of times, it is very difficult to judge for field applications
