3BSE013236R1 | ABB TU835V1 MTU with Spring Terminals

Overview

The ABB TU835V1 (Part Number: 3BSE013236R1) is an Extended Module Termination Unit (MTU) designed for the S800 I/O platform. It functions as a single-slot, non-redundant, passive interface baseplate that connects one S800 I/O module to the ModuleBus. Featuring three rows of spring-clamp terminals instead of traditional screw blocks, the TU835V1 provides vibration-resistant, fast field-side signal termination and power distribution links without active electronic failure points on the board.

Key Operational Features

• Spring-Clamp Wiring Maintenance: Replaces traditional compression screws with high-tension spring clips, significantly reducing cabinet assembly time and eliminating periodic terminal screw retightening tasks.
• Vibration Resistance: Continuous spring pressure maintains stable surface contact, making this MTU ideal for deployment in heavy machinery rooms or high-vibration industrial sectors.
• Extended Three-Row Termination: Features three horizontal rows of spring terminals to efficiently aggregate process loops and return tracks on a single footprint, lowering panel layout density.
• Mechanical Coding Safeguards: Incorporates field-configurable mechanical keys to restrict slot insertion to specified module types, preventing accidental component voltage damage during module swaps.

Installation Notes

• Snap the TU835V1 MTU firmly onto the cabinet DIN rail until the rear locking mechanism fully engages.
• Ensure the integrated grounding clip makes solid, paint-free contact with the metallic rail to guarantee reliable noise rejection.
• Set the mechanical keying wheels on the MTU face to exactly match the designated keying profile of the target S800 I/O module before slotting the electronics in.
• Depress the spring actuator using a small screwdriver tool, insert the stripped field wire (approx. 8–9 mm strip length), and release the tool to establish a gas-tight electrical bond.
