Yokogawa ATSS3S-0 / ATSS3D-0 are pressure-clamp terminal assemblies used with ASI533 analog output modules in CENTUM field I/O. ATSS3S-0 provides the single terminal execution, while ATSS3D-0 provides the dual-redundant terminal execution for an arrangement that uses paired output modules.
At the field boundary, Yokogawa ATSS3S-0 / ATSS3D-0 land the eight 4 to 20 mA output loops and preserve the terminal organization required by the ASI533 built-in barrier system. The terminal choice therefore follows the installed module topology; it is not an interchangeable cosmetic accessory.
During installation, Yokogawa ATSS3S-0 / ATSS3D-0 must keep channel identity, polarity, shielding and the approved hazardous-area separation aligned with the cabinet record. The D version also requires both redundant paths to be traced before either side is commissioned.
