Product Description

The ABB TU838 is an extended module termination unit (MTU) designed for use within the ABB S800 I/O distributed control platform. It provides the physical mounting base and connection interface for I/O modules, featuring built-in fused power distribution connections tailored to supply power directly to field-mounted instruments and transducers.

Product Parameters

  • Manufacturer: ABB
  • Product Series: S800 I/O System
  • Part Number / Catalog ID: 3BSE008572R1 (TU838)
  • Signal Terminals: 16 signal connections
  • Power Outlets: 2×4 fused transducer power outlets
  • Return Terminals: 2×4 return connections
  • Power Supply Terminals: 2×2 L+ and 2×2 L- terminals
  • Mounting Orientation: Horizontal mounting on standard DIN rail
  • Protection Class: IP20

Product Advantages

  • Integrated Fused Protection: Built-in fuses protect field transducer power circuits against overloads and short circuits, boosting system safety.
  • Simplified Field Wiring: Centralizes power distribution and signal termination on a single mounting block, reducing external terminal strip requirements.
  • Hot-Swap Support: Allows quick replacement of I/O modules without disconnecting field wiring or shutting down system power rails.

Important Considerations and Precautions

  • Power Disconnection: Always remove external power before servicing fuses, wiring, or unseating connected I/O modules to prevent electrical shock.
  • Fuse Replacement: Ensure replacement fuses match exact manufacturer ratings to maintain proper circuit protection.
  • Environmental Limits: Install inside an appropriate protective industrial enclosure to maintain the IP20 rating against dust and moisture.

Product Applications

  • Process Control Systems (DCS): Deployed in chemical plants, oil refineries, and power generation facilities to manage field instrument signals.
  • Transducer Power Management: Ideal for loops requiring direct power distribution and fusing for 2-wire or 4-wire transmitters.
  • Industrial Automation: Links plant floor sensors and actuators with central programmable controllers.
