PLC power lines, I/O power lines, input signal lines, output signal lines, AC lines, and DC lines should be wired separately as much as possible. The switch signal line and analog signal line should also be wired separately. Both switch signal line and analog signal line should use shielded wire, and the shielding layer should be reliably grounded. Due to the opposite direction of current in the twisted pair. Equally sized, it can cancel out the noise caused by induced currents. Therefore, signal wires are often twisted pair or shielded.
The I/O Modules can be connected to field devices by terminal connection or with a terminal block via a KS cable interface adapter. A customer-furnished MIL cable can also be used to connect to the I/O Module. The following explains the terminal blocks as well as the signal wiring that can be paired with the I/O Modules.
A pressure clamp terminal block is provided for the terminal connection with field devices. To expand terminals via terminal boards, connect a KS cable adapter to an I/O Module. When using a customer-furnished MIL connector cable, can directly connect to an I/O Module.
Note: One dual-redundant terminal block is used to connect two adjacent I/O Modules.
Note: A cable connector cover (ACCC01) is provided for the connection via a MIL connector.
1: A cable can be connected directly to the I/O module without using an adapter.
2: For the combination of AAI135/AAI835/AAP135; ATK4A; AEA4D, either 2-Wire Transmitter 2-Wire Input (transmitter power supply type) or 4-Wire Transmitter 2-Wire Input (without transmitter power supply) can be selected for each input channel.
3: For the combination of AAI135/AAP135; ATI3A; AEA3D and the combination of AAI835; ATB3A; AEA3D, all input channels are 2-Wire Transmitter 2-Wire Input (transmitter power supply type).
4: When AAT145 module is connected to MTC terminal board or TETC terminal board, the module is 15-Channel.
