Terminal Board SEA4D-06 YOKOGAWA

The SEA4D-06 is an analog input terminal block manufactured by Yokogawa Electric Corporation for DCS systems, suitable for single and redundant configurations. It supports 16/32 channels of analog input/output, direct connection of voltage and current signals, and four 40-pin IDC connectors for single or redundant input/output. Field connection is via four M3.5 screw terminal blocks with transparent covers; the terminal blocks can be fully unplugged and re-plugged.

SEA4D-06 is compatible with AAI135, AAI835, and AAP135 modules of DCS. KS1 is the associated cable. The insulation resistance is not less than 10MΩ (500VDC). The temperature at which the device is used is 0-50℃, and the humidity is 10-90% RH.

Installation Requirements:

Ensure that the model and number of the terminal boards of SEA4D-06 are correct, and that the appearance is intact and not distorted.

Verify that the cable (KS1), terminal blocks, a nd screws are complete and in proper condition.

The installed DCS modules (AAI135, AA1835, AAP135, etc.) have identical types.

Carefully place the terminal board in the installation position and uniformly tighten it with screws.

Make sure that the terminal board is securely fixed without looseness.

Properly align the KS1 cable IDC connector to the 40P IDC socket on the terminal board (four groups) and push it down vertically until it locks in position for proper contact.

During a single configuration, one group of IDC sockets is connected. In a redundant configuration, two groups of IDC sockets are connected.

The other end of the cable should be connected to the IDC interface of the respective DCS module (AAI 135, AAI 835, etc.), with care of the interface direction not to allow reverse insertion.

You must ensure the correct connection of the two sets of IDC cables in the redundant mode, and ensure normal communication between the modules.
