Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to description figure 1, a modularization relay, including installation base, circuit board, pilot lamp, controlling element and plug connector, the circuit board is located on the installation base, the pilot lamp, relay controlling element and plug connector are located on the circuit board, the circuit board includes the short circuit return circuit, the input contact, output contact and rectifier bridge, the plug connector with input contact and output contact electricity are connected, relay controlling element with the rectifier bridge electricity is connected, relay controlling element is including the relay coil. The indicator light is a light emitting diode. The input contacts on the circuit board include a common terminal contact. The input contact terminal contact on the circuit board comprises a common terminal contact. The voltage connected with the input terminal contact is 0-24V.

Referring to the specification and the attached figure 2, the power supply is input from an input 1 and an input 2, and is converted into a direct current power supply with fixed polarity after being converted by four internal diodes. In the module, the light emitting diode and the relay plug-in require a direct current power supply with fixed polarity to drive the light emitting diode and the relay plug-in to work, and in practical application occasions, a common end of the power supply has a positive electrode and a negative electrode, so that the electrode conversion of an input power supply is needed in order to get rid of the inherent limitation of an execution element on an application scene. In this module, Icom is connected to the first input of each rectifier bridge, INn is connected to the second input of each rectifier bridge, the positive output terminal of the second rectifier bridge is connected to the positive terminal of the actuator, and the negative output terminal is connected to the negative terminal of the actuator. When Icom is connected to 24V and INn is connected to 0V, and when Icom is connected to 0V and INn is connected to 24V, the output electrodes of the rectifier bridge are the same. Therefore, when the control occasions are different, the use requirement can be met only by changing the electrode of the public end.

Referring to the specifications 1-2, the specific use mode of the utility model is as follows: input end use mode 1: when the input common terminal contact 1, Icom is connected with 24V, the input terminal contact 2, IN1 receives the 0V input signal sent by the PLC, the relay coil is switched on and attracted, and the output terminal O1 is switched on with the output common terminal Ocom (the same principle is applied to other terminals).

Input end use mode 2: when the input common terminal contact 1 and Icom are connected to 0V, the input terminal contact 2 and IN1 receive a 24V input signal sent by the PLC, the relay coil is switched on and attracted, and the output terminal O1 is switched on with the output common terminal Ocom (the same principle is applied to other terminals). The output common terminal can be connected with 24V or 0V according to the actual production and use requirements. The utility model discloses a modular assembly design increases the conversion buffer circuit in the circuit board for the public end can insert 0V or 24V does not have the polarity restriction. The patch circuit is added in the design of the circuit board, and an additional and independent short connecting piece is not needed in the using process. The mechanical life is more than 2000 ten thousand times (the on-off frequency is 180 times/min).
