More Information

Overview Manuals Specifications Sensor Channels I/O Fit

Features:

  • Eight fused sensor outlets: The official layout protects grouped sensor-power feeds.
  • Sixteen channels: Forty process connections serve signal and power duties.
  • Mixed I/O scope: ABB lists selected analog input, digital input, and digital output modules.

TU838 provides a 16-channel termination base where sensor-power distribution is part of the MTU configuration.

The eight fused sensor-power outlets and twelve 0 V terminals should be mapped before a field-wiring transfer.

Match TU838 and 3BSE008572R1 with the installed I/O article, load schedule, and mechanical keys.

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