Description

Technical Field

[0001] The utility model relates to a wiring terminal integrated module, in particular to an integrated module of a terminal row and a relay module. Background Art

[0002] At present, the wiring method of terminal blocks and components such as relays is wire harness connection. The production process requires wire cutting, wire stripping, number tube installation, screw fixing, etc., and the middle needs to pass through the wire trough. The overall layout area is large, resulting in a large control cabinet, and it takes a lot of manpower and time to complete the wiring, which is inefficient. At the same time, it also consumes more connecting wires. Therefore, the development of a terminal block and relay module integrated module has become a problem that needs to be solved by technicians in this field. Utility Model Content

[0003] The utility model is to solve the above-mentioned shortcomings and provides a terminal block and relay module integrated module.

[0004] The above-mentioned purpose of the utility model is achieved through the following technical scheme: a terminal block and relay module integrated module, including a module base, the module base is provided with an output terminal block, an isolation relay, a DC power input terminal block and a signal input terminal block, the DC power input terminal block is connected to a 24V DC power supply, the signal input terminal block is connected to a PLC output module, the output terminal block is connected to a load common terminal, and the output terminal block is connected to a load circuit; the signal input terminal block is connected to the output terminal block through an isolation relay, so that the isolation relay completely separates the signal input terminal block (input signal) from the output terminal block (output load circuit), and when the output load is overloaded or short-circuited, the PLC output module can also be protected from being burned.

[0005] Furthermore, the module base is provided with a disassembly tool holder and a relay disassembly tool is placed thereon. The isolation relay can be disassembled separately. When one point of the isolation relay is damaged, a new relay can be replaced without replacing the entire module, thereby reducing maintenance costs. When the relay disassembly tool is needed, it can be pulled out. After use, the relay disassembly tool can be inserted into the disassembly tool holder and placed.

[0006] Furthermore, the module base is provided with indicator lights, including a signal output indicator light and a power indicator light. The signal output indicator light is connected in series with the isolation relay, and the power indicator light is connected in series with the DC power input terminal block.

[0007] Furthermore, the terminal block and relay module integrated module is set to an 8-bit, 16-bit or 32-bit integrated module, the isolation relays are correspondingly set to 8, 16 or 32, and the output terminal block and signal input terminal block are correspondingly provided with 8-bit, 16-bit or 32-bit wiring terminals.

[0008] The advantages of the utility model compared with the prior art are: without affecting the original control logic, the utility model greatly reduces the layout space, shortens the wiring time of the control cabinet, reduces the volume of the control cabinet, improves the integration of the control cabinet electrical box, reduces wiring, reduces connecting wires, and reduces material loss.

DETAILED DESCRIPTION

[0013] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0014] like Figure 1 , Figure 2As shown, a terminal block and relay module integrated module includes a module base 1, the module base 1 is provided with an output terminal block 2, an isolation relay 3, a DC power input terminal block 4, a signal input terminal block 5, an output indicator light 6 and a power indicator light 7, the signal input terminal block 5 is connected to a line row module 11, and the line row module 11 is provided with a line row input connection 12, the terminal block and relay module integrated module is set to an 8-bit, 16-bit or 32-bit integrated module, the isolation relay 3 and the output indicator light 6 are set to 8, 16 or 32 respectively, and the output terminal block 2 and the signal input terminal block 5 are provided with 8-bit, 16-bit or 32-bit wiring terminals. In this embodiment, the terminal block and relay module integrated module is set to 16 bits, and the output terminal block 2, the isolation relay 3, the signal input terminal block 5, and the output indicator light 6 are consistent in number and correspond one to one. The DC power input terminal row 4 (24V, 0V) is connected to a 24V DC power supply, and the 00-0F terminals of the signal input terminal row 5 are connected to the PLC output module. When the PLC has a signal output, the corresponding relay coil is energized, generating a magnetically attracted armature to push the contact, so that the normally open contact is closed and the load circuit is connected. At the same time, the LED indicator of the corresponding relay lights up, which can intuitively reflect the output working condition of the PLC. The CO-CF terminals of the output terminal row 2 are connected to the load common terminal, and the CO-CF terminals of the output terminal row 2 are connected to 16 groups of load circuits. The isolation relay 3 completely separates the input signal from the output load circuit, and can also protect the PLC output module from being burned when the output load is overloaded or short-circuited. At the same time, the isolation relay 3 can be disassembled separately, and a new relay can be replaced when one point of the isolation relay 3 is damaged. There is no need to replace the entire module, which reduces maintenance costs.

[0015] The isolation relay 3 is installed in a fixed position 10 on the module base 1. In order to facilitate the disassembly and replacement of the isolation relay 3, the module base 1 is provided with a disassembly tool holder 8 and a relay disassembly tool 9 is placed thereon. The disassembly tool 9 can be pulled out when needed, and can be inserted into the disassembly tool holder 8 and placed thereafter.
