11 pin timer relay is a type of relay that is used to control different types of electric devices. The timer relay has 11 pins that are used to connect it to different electric devices. The connection of the timer relay is done by wiring it to the electric circuit. In this journal article, we will discuss the wiring diagram for 11 pin timer relay in detail.
Parts Required for Wiring 11 Pin Timer Relay
Before we start discussing the wiring diagram for 11 pin timer relay, it’s important to know the parts required for wiring it. The following are the parts required for wiring 11 pin timer relay:
- 11 pin timer relay
- Jumper wires
- Power supply
- Electric devices (that will be controlled by the timer relay)
11 Pin Timer Relay Wiring Diagram
Now let’s discuss the wiring diagram for 11 pin timer relay.
| Pin Number | Connection |
|---|---|
| 1 | NC (Normally Closed) contact |
| 2 | NO (Normally Open) contact |
| 3 | COM (Common) contact |
| 4 | Coil A |
| 5 | Coil B |
| 6 | A1 contact |
| 7 | A2 contact |
| 8 | B1 contact |
| 9 | B2 contact |
| 10 | NC contact |
| 11 | NO contact |
Pin 1, 2, and 3 are the contacts of the timer relay. Pin 4 and 5 are the coil pins, pin 6 and 7 are the A1 and A2 contact pins, and pin 8 and 9 are the B1 and B2 contact pins. Pin 10 is the NC (Normally Closed) contact, and pin 11 is the NO (Normally Open) contact.
Wiring Steps for 11 Pin Timer Relay
The following are the wiring steps for 11 pin timer relay:
Step 1: Connect Power Supply
The first step is to connect the power supply to the timer relay. The power supply should be connected to pins 4 and 5 of the timer relay.
Step 2: Connect Electric Devices
The next step is to connect the electric devices that will be controlled by the timer relay. The electric devices should be connected to pins 1, 2, and 3 of the timer relay.
Step 3: Connect A1 and A2 Contacts
The A1 and A2 contacts should be connected to an external switch that will be used to control the timer relay. The A1 contact should be connected to the switch, and the A2 contact should be connected to the power supply.
Step 4: Connect B1 and B2 Contacts
The B1 and B2 contacts should be connected to another external switch that will be used to control the timing of the timer relay. The B1 contact should be connected to the switch, and the B2 contact should be connected to the power supply.
Step 5: Test the Connection
After completing the above steps, test the connection by turning on the power supply and pressing the external switches. The electric devices should turn on and off based on the timing set by the external switches.
