|---|---|
Hazardous Area Process Monitoring in Petrochemical & Oil & Gas Facilities | ABB TU890 3BSC690075R1 Directly connects to NAMUR proximity sensors or switches within Zone 1/21 or Zone 2/22 hazardous areas for monitoring valve positions, level limits, flame detectors, or pressure switches. The integrated IS protection ensures compliance with ATEX/IECEx standards while reducing cabinet space and wiring complexity. |
| Critical Safety Interlock Systems in ManufacturingPotential difference between input | ABB TU890 3BSC690075R1 Used on safety doors, guard positions, and emergency stop circuits where high integrity and fault detection are paramount. The galvanic isolation per channel prevents fault propagation, and the line monitoring feature ensures any wire break or short circuit is immediately detected and signaled. |
| Packaging, Material Handling & Assembly Line Sequencing | ABB TU890 3BSC690075R1 Monitors the status of sensors (e.g., part present/absent, position verified) in automated production lines. The module's ability to power NAMUR sensors simplifies wiring, and the individual channel isolation protects against ground loop issues that can cause erroneous signals. |
| Integration with Compact Motor Terminal Units (MTUs) | When paired with the TU890 (Ex version) or TU891 (non-Ex version) Compact MTU, the system forms a highly space-efficient distributed I/O solution for motor control centers. This combination allows for direct two-wire connection to motorized actuators, pumps, or fans, enabling both control and status feedback (e.g., running, fault, ready) through a single compact interface, streamlining panel design and field wiring. |
