ABB 07KT97 / 07KT97B (GJR5253000R0200) – Communication Processor Module for Advant/Master Systems

The ABB 07KT97B (order code GJR5253000R0200) is a communication processor module used in ABB Advant and legacy Master-based control systems. From my experience, it’s typically deployed as the field/plant network bridge for remote I/O, third‑party serial devices, and higher‑level HMI/SCADA links. If you’re keeping an Advant Controller installation productive without a risky rip‑and‑replace, this module is one of those practical spares that keeps the backbone talking.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery time: 1 week if in stock; no more than one month at the latest
• Payment terms: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Advant/Master system integration: Designed as a plug‑in comms processor for ABB Advant-based controllers and racks, maintaining compatibility with existing backplanes.
• Field and serial connectivity: Typically supports ABB fieldbus plus serial links (RS‑232/RS‑485) to connect gateways, analyzers, drives, and legacy instruments.
• Diagnostics LEDs: You might notice clear front‑panel status indicators that speed up commissioning and fault isolation.
• Firmware/feature stability: In many cases, B‑revision modules show improved robustness and lifecycle support over earlier revisions.
• Backplane powered: Draws regulated 5 VDC from the Advant rack, simplifying cabinet wiring and spares management.
• Service-friendly: Hot‑swap is generally not recommended, but the guided plug‑in form factor makes planned replacement quick and safe.

Technical Specifications

Application Fields

This module is commonly used where Advant controllers remain in service and uptime is crucial:

• Power generation (balance‑of‑plant integration, turbine/boiler subsystems)
• Pulp & paper (machine sections, drives communications, quality systems)
• Metals & mining (mill stands, process lines, legacy serial gateways)
• Oil & gas and petrochemical (compressor packages, analyzer shelters)
• Water & wastewater (I/O expansions, telemetry links, SCADA ties)

One maintenance lead told us their 07KT97B stabilized intermittent serial comms to a decades‑old analyzer—no code changes, just a clean module swap and a quick parameter check. That sounds small, but it kept a critical loop from drifting out of spec.

Advantages & Value

• Reliability: Proven card design; stable operation in high‑duty cabinets, typically with long MTBF in installed base.
• Compatibility: Matches Advant/Master backplanes and firmware chains, cutting integration time and risk.
• Cost savings: Extends the life of existing systems—no immediate migration budget or downtime.
• Technical support: We assist with part identification (07KT97 vs 07KT97B), basic parameter notes, and shipment testing.

Installation & Maintenance

• Cabinet & environment: Install in a clean, dry control cabinet; 0–55 °C; keep airflow around the rack unobstructed.
• Grounding & wiring: Ensure proper panel earth; use shielded twisted pair for serial/fieldbus; route away from VFD power cables.
• ESD precautions: Handle with antistatic strap; power down the rack for card insertion/removal unless ABB doc explicitly allows otherwise.
• Commissioning tips: Verify node addresses/baud rates; check front LEDs for link/traffic; keep a backup of working parameters.
• Routine maintenance: Annual connector reseat/inspection; dust cleaning with dry air; firmware/parameter review when plant changes occur.

Quality & Certifications

• CE marked; produced under ISO 9001 quality systems
• Typically UL Recognized component for industrial control equipment
• RoHS compliant in most cases for supplied revisions
• Standard warranty: 12 months (365 days) from shipment

Note: The 07KT97B (GJR5253000R0200) is the widely used revision; it appears to be backward compatible within many Advant/Master installations. If you’re replacing a 07KT97 (non‑B), share your rack and firmware details—we’ll match the correct variant to avoid surprises on site.
