Utility model content

In view of this, the main purpose of the utility model is to provide a kind of structure is simple, it is versatile, facilitate extension, The expansible relay board of built-up time and maintenance cost is greatly saved.

To achieve the goals above, the technical solution of the utility model is as follows:

A kind of expansible relay board, including integrated digital imput output circuit plate are equipped with extremely on the board Lack a relay mould group, a placement relay interface plate is at least set on the integrated digital imput output circuit plate Card slot, the relay driving IC for controlling the relay interface circuit, the relay are also at least set on the board Device interface board is connect by a winding displacement at least one relay mould group.

It is described that 8 relay mould groups are provided on integrated digital imput output circuit plate.

It is described that the card slot and 2 that 2 are placed relay interface plates are provided on integrated digital imput output circuit plate Relay driving IC, driving IC control a relay interface circuit respectively, there is 16 relay mould groups on the circuit board, should 2 relay interface plates control 8 relay mould groups by a winding displacement respectively.

The relay driving IC is that model is 2803IC.

A resistance and a LED display lamp are provided in the relay mould group, which is used to control the LED light Brightness.

The socket powered to relay mould group is additionally provided in the relay mould group.

The beneficial effects of the utility model are: 1) when the utility model is used, as long as relay interface plate is plugged on electricity It can be used in the slot of road plate, versatile, structure is simple；2) the utility model assembling is simple, and assembling is greatly saved Time maintains easily, and maintenance cost is greatly saved；3) the utility model safety is good, highly reliable, makes suitable for popularity With.

Detailed description of the invention

Fig. 1 is the expansible relay board structural schematic diagram of this practicability embodiment.

Specific embodiment

With reference to the accompanying drawing and the embodiments of the present invention are described in further detail utility model.

Embodiment 1

Referring to Fig. 1, the expansible relay board, including integrated digital imput output circuit (PIODIO) plate, at this Circuit board is equipped at least one relay mould group 1, is at least arranged one on the integrated digital imput output circuit plate The card slot for placing relay interface plate 4 (CON1) is also at least arranged one on the circuit board (PIODIO) and controls the relay The relay driving IC3 of interface circuit, the relay interface plate 4 are connected by a winding displacement and at least one relay mould group 1 It connects.

In the present embodiment, it is provided with location hole 2 on integrated digital imput output circuit plate, fixes the electricity for facilitating Road plate；8 relay mould groups are additionally provided in circuit board, a relay driving IC3 is provided on the circuit board, which is type It number is 2803IC, for controlling the interface circuit on the relay interface plate 4 (CON1), the relay interface plate 4 passes through A piece winding displacement is connect with 8 relay mould groups.

Embodiment 2

Referring to Fig. 1, the difference is that, this is described on integrated digital imput output circuit plate with above-described embodiment It is provided with 2 and places the card slot of (CON1) plate of relay interface 4 and relay interface 6 (CON2) plate, and there are 2 relays to drive Dynamic IC3 and IC5, driving IC3 are for controlling relay interface 4 (CON1), and driving IC5 is for controlling relay interface 6 (CON2)；There are 16 relay mould groups on the circuit board, (CON1) plate of relay interface 4 and relay interface 6 (CON2) plate 8 relay mould groups are controlled respectively by a winding displacement, and two relay interface plates control altogether 16 relay mould groups.
