How to Make a Remote Controlled Pulley Hoist Mechanism Circuit Part-2

The earlier conversation described precisely how the pulley hoist mechanism ought to be set, subsequent, according to the demand the motor is meant to be managed by means of a remote control circuit.
These days RF remote modules might be obtained fairly inexpensively and very easily from the local electronic shops, so it’s suggested to buy one rather than trying to make one.

For hard core enthusiasts who desire to develop the whole thing with their own hands, a relevant circuit design is mentioned within this Article
Once you have acquired ready Rx, Tx modules, you will discover the receiver Rx units of these RF modules acquiring built-in relays nevertheless these relays could possibly be quite inferior with their load handling capacity thereby ought to be reinforced with external relays, particularly when the load is a high current type similar to the existing application.
Ideally buy a two-relay RF module simply because we require just two relays for managing the reverse forward motions of the motor. Common illustration of a two relay module could be observed in the following image.


The enclosed relays in the Rx PCB will function as a reaction to the pressing of the associated buttons on the Tx transmitter module, so it’s all about tracing out the N/O, N/C and the poles of these two relays and wire them up with the external heavy duty relays for enforcing the preferred motor reverse forward motions.
The following diagram thoroughly details the wiring layout of the relays, once the wiring is finished in accordance with the demonstrated diagram one of the buttons may cause the motor to rotate clockwise while pressing the other would certainly flip the motor direction anticlockwise.


When no buttons are functional the motor would stationery. The motor would wind or unwind the pulley ropes as long as the appropriate buttons of the Tx is held pressed by the user and would halt once produced.
On the other hand, you could look at having fun with the in-built Rx modules “relay operation selector” connections by inserting the plugs properly until the needed spec are located whereby the relay is permitted to toggle ON/OFF with each and every alternate press of the Tx buttons along with the user do not have to maintain the pertinent Tx button pressed constantly for performing the meant motor rotations.
