Step 3: Connect the Signal Wires
The next step is to connect the signal wires to the input channels of the 1746 IA16 module. The wiring diagram of the module shows that each input channel has two terminals: one for the positive (+) signal wire and one for the negative (-) signal wire. Make sure to connect the wires according to the correct polarity.
Step 4: Tighten the Terminal Screws
After connecting the signal wires, tighten the terminal screws of the 1746 IA16 module using a screwdriver to ensure a secure connection.
Step 5: Power On the System
Finally, power on the PLC and the 1746 IA16 module to test the input wiring. The green LED indicator of the module should illuminate, indicating that the module is receiving power.
Power Wiring
The power wiring of the 1746 IA16 module involves the following steps:
Step 1: Power Off the System
Before starting the power wiring, make sure to power off the PLC and the 1746 IA16 module to avoid any electrical shock or damage to the equipment.
Step 2: Connect the Power Supply
The first step in the power wiring is to connect the power supply to the 1746 IA16 module. The wiring diagram of the module shows that the positive (+) and negative (-) terminals of the power supply should be connected to the corresponding terminals of the terminal block on the module.
Step 3: Tighten the Terminal Screws
After connecting the power supply, tighten the terminal screws of the 1746 IA16 module using a screwdriver to ensure a secure connection.
Step 4: Power On the System
Finally, power on the PLC and the 1746 IA16 module to test the power wiring. The green LED indicator of the module should illuminate, indicating that the module is receiving power.
