Universal binary combination logic module group of strong and weak current isolation type

Abstract

The invention reveals a universal binary combination logic module group of a strong and weak current isolation type, and the logic module group comprises a strong current input unit, an output unit, aweak current signal unit, a relay J1, a relay J2 and a plurality of jack units. Switching contacts of the relay J1 are divided into two ways which are connected with the strong current input unit, and switching contact of the relay J2 are divided into two ways which are connected with the output unit. The two relays are connected with the weak current signal unit. The plurality of jack units aregrouped to be connected with the normally-opened contacts of the relays J1 and J2, and the binary logic between the two relays is completed through a jumper wire. Aiming at a condition that an onsiteconfiguration circuit refers to a relay part, the module group provided by the invention can achieve the replacement of a line through plugging like a relay or directly order the lines, thereby avoiding the tedious and complicated wiring, increasing the number of logic types of the binary combination, and improving the universality of the module group. Moreover, the module group is simple in structure, and conveniently achieves the forwarding and reverse rotation of the motor, colorful LED lights, acceleration and deceleration.

Description

technical field [0001] The invention relates to a relay application peripheral circuit, in particular to a general binary combination logic module used for strong and weak current isolation and multi-relay connection. Background technique [0002] At present, as the most basic electrical component, the relay is widely used in the field of automatic control to complete signal transmission, power distribution, circuit isolation, and load conversion due to its inherent high conversion depth, multi-channel synchronous switching, and strong anti-interference ability. Wait for the task. [0003] Because it is common and widely used, the application of a single relay is relatively simple and convenient. When multiple relays are applied to the circuit, complex circuit drawings will be involved. For example: 14-pin intermediate relay involves 4 single-pole double-throw switches, 2 A pin to control the solenoid coil. When more than 2 relays are connected and connected, workers will ...
