Product Overview

• PN: TU810V1
• Part No: 3BSE013230R1
• Brand: ABB
• Series: S800 I/O Distributed I/O System compatible with System 800xA DCS
• Type: Compact Module Termination Unit Passive Terminal Base

• Function: Passive wiring base installed under S800 series I/O modules. It acts as connection bridge between field sensors, actuators and upper I/O modules, finishing access of 16 groups of signals and auxiliary power. It transmits ModuleBus backplane signals to upper modules and cascades adjacent terminal units, automatically generating station addresses without manual dial setting, enabling daisy-chain expansion of I/O stations.

Core Features

• 16 signal terminals divided into two groups of 8 channels, maximum rated signal voltage 50V, integrated terminals for field signal and auxiliary power supply
• Internal ModuleBus routing circuit, allowing sequential cascade of multiple units for flexible I/O point expansion
• Dual mechanical coding lock with 36 combination modes to physically avoid inserting mismatched incompatible I/O modules
• Quick snap-on DIN rail installation with grounding buckle to guarantee cabinet equipotential grounding
• Passive circuit with zero power consumption and low failure rate, supporting hot swap of upper I/O modules
• Slim compact structure to save cabinet space, supporting both horizontal and vertical installation

• Conformal coated circuit board for dustproof, moistureproof and anti-interference performance during long-term cabinet operation
