ABB TK851 is an original Profibus DP master communication module tailored for the ABB AC800M DCS industrial control platform, widely applied as a core high-precision temperature transmission module in thermal process control systems. It acts as a high-speed data bridge between PM86x series main CPU and field temperature measuring instruments including Pt100 thermal resistance, thermocouple acquisition cards, furnace temperature transmitters and heating/cooling actuators. It realizes real-time high-speed collection, transmission and closed-loop regulation of temperature signals to guarantee ultra-stable precise temperature control for continuous industrial production lines. We supply 100% brand-new genuine original ABB units with abundant in-stock inventory, global fast delivery and standard 12-month factory warranty, ideal for new DCS cabinet configuration, system renovation and emergency spare replacement for temperature control industrial systems.Core Technical Specifications 表格ItemStandard ParameterModel VariantTK851V007 / TK851V010Matching Control PlatformABB AC 800M DCS Rack, PM861/PM864/PM866 CPU SeriesFieldbus StandardProfibus DP IEC 61158 Type 3Max Communication Rate12 Mbps (auto-adaptive 9.6 kbps ~ 12 Mbps)Max Connectable Field SlavesUp to 31 temperature sensors, I/O modules and regulatorsElectrical Isolation500 VAC reinforced isolation between bus port and rack backplaneStatus IndicatorPWR power, RUN operation, COM communication/fault LED indicatorsInstallation FeatureSingle-slot plug-in rack mounting, support hot swapPower SupplyPowered by AC800M rack backplaneOperating Temperature0℃ ~ +60℃Storage Temperature-40℃ ~ +85℃Protection ClassIP20 (cabinet installation only)International CertificationsCE, UL 61010-1, IEC 61326-1 EMC industrial safety standardNet WeightApprox. 0.56kgOriginal ABB Quality & High Precision Core Advantages1. Ultra-Fast Bus Transmission Delivers High Precision Temperature ControlAdopts high-speed Profibus DP bus transmission with microsecond-level signal response speed. It rapidly synchronizes multi-point temperature measurement data from kilns, reactors and pipelines, instantly transmitting heating/cooling adjustment commands to field actuators. Ultra-low signal delay effectively eliminates temperature deviation and fluctuation, realizing constant temperature control with high precision, avoiding product quality instability caused by slow temperature feedback in batch manufacturing processes.2. Reinforced Isolation & Industrial Anti-Interference Design500VAC reinforced isolation between communication interface and backplane circuit blocks grid surges, harmonic noise and ground potential difference interference from metallurgical, chemical and power plant workshops. Built-in multi-stage digital signal filtering prevents communication disconnection, temperature data distortion and control logic disorder under strong electromagnetic environments, ensuring 24/7 stable operation of high-precision temperature monitoring loops.3. Industrial-Grade Original Components, Reliable Long Service LifeAll circuit boards adopt ABB original industrial chips and conformal coated reinforced PCB, each finished module passes strict full-load aging, vibration and damp-heat cycle testing before factory delivery. Outstanding shock resistance and anti-aging performance adapt to harsh workshop environments, featuring ultra-low failure rate and superior MTBF index compared with generic imitation modules, fully reflecting consistent original ABB industrial quality standards.4. Hot-Swap Modular Structure Minimizes Production DowntimeStandard single-slot card design supports hot replacement under authorized system configuration. Maintenance staff can replace faulty TK851 without full system power cut, drastically shortening production halt time during temperature control system communication failures, reducing production loss and maintenance labor costs for manufacturing enterprises.5. Large-Capacity Node Expansion for Multi-Point Temperature MonitoringSingle module supports up to 31 Profibus slave devices, fully compatible with all ABB analog temperature acquisition I/O cards, valve positioners and frequency converters. It easily realizes distributed multi-point temperature measurement and centralized closed-loop control for large rotary kilns, chemical reaction workshops and power boiler thermal systems, saving extra bus module investment for later production line upgrades.Main Industrial Application Scenarios Chemical & Petrochemical Process Industry: Precise closed-loop temperature regulation of reactors, distillation towers and heating furnaces, pipeline temperature interlock monitoring Thermal Power Plant Thermal Control: Boiler flue gas and steam pipeline temperature collection, bus networking for desulfurization & denitrification temperature control systems Metallurgy & Heat Treatment Industry: Multi-point high-precision automatic temperature control for annealing furnaces and roller kilns Pharmaceutical & Food Manufacturing: Constant temperature adjustment for sterilization tanks and drying ovens, centralized workshop temperature monitoring Cement Building Material Industry: Real-time temperature data transmission and linkage control of rotary kilns and cooling machines Original In-Stock Supply & Global Complete ServiceAll ABB TK851 high precision temperature modules we provide are 100% genuine original ABB factory products, equipped with complete sealed original packaging and official factory performance test reports, covered by a formal 12-month warranty against manufacturing defects under rated operating conditions.
