Detection device for terminal module KDOR01

Abstract

The utility model relates to the technical field of electrical automatic control, in particular to a detection device for a terminal module KDOR01, and aims to solve the problem that a control system fails finally due to the fact that a fault state cannot be judged after a fuse in a relay terminal KDOR01 module fails at present. The device aims at solving the problems that an internal fuse of a relay terminal module KDOR01 is impacted and damaged due to on-site abnormal conditions, so that the relay terminal module KDOR01 cannot output signals when the relay terminal module needs to act and output, and the internal fuse of the terminal module KDOR01 cannot observe whether the relay terminal module KDOR01 works normally or not under normal conditions, so that the relay terminal module KDOR01 cannot output signals when the relay terminal module KDOR01 works normally. The condition that a shutdown protection signal cannot be output when key equipment needs to be subjected to interlocking shutdown, and serious consequences are caused is avoided, the state of the relay terminal module KDOR01 can be visually observed in daily work, the hidden danger that the protection signal cannot be output when needing to be output is effectively avoided, and the occurrence rate of serious faults is reduced.

Description

TECHNICAL FIELD

[0001] The utility model relates to electrical automatic control technical field, concretely relates to a detection device for terminal module KDOR01. BACKGROUND

[0002] In recent years, the process of automatic equipment domestic goods is increasingly accelerated, and the products of automatic industry famous brand and Lixi company are used in production site in large quantities, the DO relay terminal module K-DOR01 is internally added with a fuse for protection and is encapsulated, but the channel state indicating lamp can only reflect the channel state, and the internal fuse state cannot be reflected, so that the fuse cannot output signal after failure, and since a large number of equipment protection interlocking uses the DO relay terminal module K-DOR01 to output shutdown protection, when the internal fuse of the module fails, and the routine inspection maintenance operation cannot judge the failure state, the control system cannot stop after outputting shutdown protection instruction, which can greatly cause the failure to expand or cause an accident. UTILITARY MODEL CONTENT

[0003] The utility model provides a detection device for terminal module KDOR01 to solve the problems in the above background.

[0004] In order to realize the above purpose, the utility model adopts the following technical scheme:

[0005] A detection device for terminal module KDOR01, including K-DOR01 terminal module, the side of K-DOR01 terminal module is connected with first coil terminal and second coil terminal, and the first coil terminal and the second coil terminal are equipped with emergency stop relay, the other side of K-DOR01 terminal module is equipped with external power supply positive pole and external power supply negative pole, and the external power supply positive pole and the second coil terminal are further connected with indicating lamp positive pole and indicating lamp negative pole, and the indicating lamp positive pole and the indicating lamp negative pole are further equipped with indicating lamp.

[0006] The utility model has the advantages of the following:

[0007] The terminal module K-DOR01 detection device provided by the utility model avoids the expansion of failure or the occurrence of accident caused by fuse failure by the way of installing indicating lamp, confirms whether the terminal module K-DOR01 is normal or not, is simple to implement, is easy to implement in production site, is low in investment, the detection method is intuitive, and the realization of the interlocking function of the key equipment is guaranteed. DRAWING EXPLANATION

[0008] Figure 1 It is the whole structure wiring schematic diagram of the utility model.

[0009] The reference signs have the following meanings:

DETAILED DESCRIPTION

[0011] The utility model will be further described below in combination with the drawings and specific embodiments.

[0012] As Figure 1 shown, a kind of detection device for terminal module KDOR01, including K-DOR01 terminal module 9, the side of K-DOR01 terminal module 9 is connected with first coil terminal 1 and second coil terminal 3, and emergency stop relay 2 is equipped between first coil terminal 1 and second coil terminal 3, the other side of K-DOR01 terminal module 9 is equipped with external power supply positive electrode 7 and external power supply negative electrode 8, and the second coil terminal 3 between external power supply positive electrode 7 is also connected with positive electrode 4 of indicating lamp and negative electrode 6 of indicating lamp, and positive electrode 4 of indicating lamp and negative electrode 6 of indicating lamp are also equipped with indicating lamp 5 between them.

[0013] The utility model in specific application, based on existing terminal module K-DOR01, it is realized by the method of installing indicating lamp 5 in terminal module KDOR01 output end closed point terminal, indicating lamp 5 is brightened after installing indicating lamp 5 due to being connected to normally closed signal, and when internal fuse fault, positive electrode 4 of indicating lamp is disconnected, indicating lamp 5 is extinguished, so that the state of relay KDOR01 terminal module 9 can be observed directly in routine work, effectively avoid the hidden danger that cannot be output when needing output protection signal, reduce the incidence of serious fault.
