Features:
- High-performance process control; supports continuous, batch, and discrete control; deterministic execution.
- Supports hot-standby configuration via TK-PRR021 redundancy module; bumpless switchover for high availability.
- Interfaces with PMIO via TK-IOLI01; communicates on ControlNet via CNI modules; controls Series A I/O directly.
The TK-PRS021 51404305-375 is the heart of Honeywell's Series A control system. As a C200 processor, it executes complex control strategies with deterministic timing, essential for continuous processes such as chemical reactors, refineries, and power boilers. The processor supports multiple control languages, including ladder logic, function block, and sequential function charts. It occupies two slots in a Series A chassis, which can be a TC-FXX (4,7,10,13,17 slots) or TK-FXX (10,13 slots) model.
High-availability applications demand that no single point of failure shuts down the process. The TK-PRS021 51404305-375 supports redundant operation when paired with the TK-PRR021 redundancy module. In a redundant configuration, two C200 processors run in parallel – one active, one standby. The redundancy module synchronizes the processors and manages bumpless switchover if the active processor fails. This capability is essential for critical processes such as ethylene crackers, FCC units, and turbine control. The switchover time is typically within one control cycle, so the process sees no disturbance.
The TK-PRS021 51404305-375 connects to field devices through multiple pathways. For local I/O, it communicates directly with Series A I/O modules installed in the same chassis, including analog (e.g., TC-IAH061, TC-OAH061), discrete (e.g., TC-IDK161, TC-ORC081), and specialty modules (e.g., TK-MDP081SI serial interface). For larger systems, it interfaces with PMIO (Process Manager I/O) via a TK-IOLI01 I/O Link Module, extending the I/O count far beyond a single chassis.
The TK-PRS021 51404305-375 Honeywell Control Processor module may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL)by the manufacturer (OEM).
