More Information

Overview Manuals Specifications Shunt-Stick Planning Vertical Installation Field Wiring Review

Features:

  • Vertical input-selection base: TU845 provides eight TY801 positions in a vertical redundant layout.
  • Forty connections: Channel, process-power, and 0 V duties use separate terminal groups.
  • Focused module list: ABB lists AI845, AI880, AI880A, and DP840.

TU845 supports per-channel voltage-or-current selection in a vertical redundant S800 I/O termination arrangement.

The shunt configuration must match the loop design, and required TY801 components should be confirmed as a separate procurement item.

Order TU845 with article number 3BSE021447R1 after checking the vertical rail space, module label, input modes, power groups, and key settings.

Availability is subject to Apter Power's current inventory and sourcing confirmation.
