Explore the Power of the Honeywell C200 Control Processor
What is the Honeywell C200 Control Processor?
The Honeywell C200 Control Processor (typically installed in a chassis slot as module TC-PRS021) is the core component of the C200 Series Controllers. The C200 Series Controllers are compact, deterministic control and safety systems designed for industrial distributed control applications. It runs Honeywell's proven Control Execution Environment (CEE) software for executing control logic, data acquisition, and I/O management.
Why Should Your Automation System Consider the C200?
Because the C200 provides reliable, field-proven control capabilities with robust I/O support and flexibility. Whether you need continuous process control or batch control, the C200 (or the upgraded C200E) provides a stable platform to run complex control strategies, making it ideal for industrial plants, refineries, water treatment plants, chemical plants, and other large process systems.
Key Features and Applications of the C200/C200E Control Processor
Based on Honeywell's official C200/C200E series controller datasheet and related documentation, the following are the key features and typical applications of the C200 control processor.
Features
Deterministic Execution and CEE Software
The C200/C200E controller incorporates Honeywell's Deterministic Control Execution Environment (CEE), which enables control strategies to run according to a constant and predictable schedule. This ensures consistent performance even in complex or time-critical processes.
Function Block Library
The controller provides a comprehensive library of control-related function blocks, such as logic functions, PID control, alarm handling, data acquisition, and maintenance statistics, allowing for the implementation of mature control logic without writing custom code.
Flexible I/O and Protocol Support
Supports multiple I/O series: A-series I/O, A-rail I/O, H-rail I/O, and Process Manager I/O. Communicates with field devices via standard industrial protocols such as FOUNDATION Fieldbus, Profibus, DeviceNet, and HART.
Scalability and Redundancy Options
The controller can be deployed as a single unit or in a fully redundant configuration—crucial for mission-critical systems requiring high availability and fail-safe operation.
Memory and Performance (C200 vs. C200E)
C200: Supports up to 4000 memory units.
C200E: Memory expansion—up to 16000 memory units—supports more complex logic, larger tag counts (e.g., up to 4095 tagged objects), and fully supports batch control standards such as ISA S88.01 through Experion Batch Manager.
Environment and Durability
Designed for industrial environments: Operating temperature 0–60 °C, storage temperature –40–85 °C; supports up to 64 I/O modules; shock resistant, suitable for transport and operation; humidity tolerance: 5–95% RH (non-condensing).
Power Supply and Backup Power
Requires +3.3 VDC @ 1 A and +5 VDC @ 1.5 A; onboard battery for RAM data retention – depending on the module, battery life is 120 hours (rechargeable) or 144 hours (replaceable).
Typical Applications
Given the above features, C200/C200E controllers are well-suited for many industrial applications including:
Continuous process control (e.g., chemical plants, petrochemical, water treatment);
Batch process control (thanks to ISA S88.01 support and Experion Batch Manager);
Hybrid processes (continuous + batch);
Legacy systems requiring modular, distributed I/O with deterministic control — especially where field I/O and various protocol devices need integration;
Environments requiring high reliability, redundancy, and long-term stable operations.
Honeywell Controller Families & Key Parameters
The table below summarizes several of Honeywell's more modern or common series, along with their representative parameters/features—comparing the C200 series to help customers choose the controller best suited to their current project needs.
|
Series / Controller Family |
Typical Use / Strength |
Key Parameters / Highlights |
|

Memory: 4000 (C200) / 16000 (C200E); I/O modules up to 64; Execution via deterministic CEE; Supports Series A / Rail I/O, standard industrial protocols; Redundancy option. |
|
|
Medium-size process control, batch or hybrid processes, modernized plants |
Handles up to ~4600 I/O; supports analog/digital I/O; flexible modular architecture; suitable for chemical, food, water treatment, smaller scale plants. |
|
|
MaserLogic-200 Series (PLC) |
Modular PLC control — small to medium automation tasks |
Rack-based, modular, easy to expand I/O; suited for automation where simple logic, scalability, and modularity matter. |
|
FSC Series (Safety 1 secialzed control) |
Specialized control / safety-critical applications |
Honeywell positions FSC for safety and control applications under its broader automation ecosystem. |
|
Newer DCS / Controllers (e.g-C300) |
High-end, scalable, secure process control for modern plants |
Much larger capacity: e.g. for C300 — 9000 XUs, embedded cybersecurity, modern protocol support (EtherNet/IP, Modbus TCP, FOUNDATION Fieldbus, Profibus, Profinet, HART etc.), better I/O HIVE scalability and flexible network integration. |
Why Choose Moore Automated for Your Honeywell Needs
Moore Automated specializes in sourcing and supplying Honeywell legacy products (such as the C200, C200E, and discontinued modules) as well as newer controllers from other Honeywell series—we typically offer competitive pricing to meet your budget while ensuring quality and reliability.
We understand that many customers are still running legacy systems (such as the C200), and replacing the entire system can be costly or disruptive to their business. Moore Automated can find hard-to-find or discontinued modules that are no longer in stock by many suppliers (such as TC-PRS021, I/O modules, and power modules).
For customers migrating to modern platforms, we also offer updated product lines (HC900, MasterLogic-200, FSC, ControlEdge)—helping you design tailored solutions to meet your application needs (batch, continuous, safety-critical, hybrid).
Commonly searched models and part numbers include C200 TK-PRS021, C200E controllers, various A-series I/O modules, and redundant modules (such as TC-PRR021) – we track market availability for these products.
