HONEYWELL TK-ODD321 Product Specification
1. Product Overview
The HONEYWELL TK-ODD321 is a high-density digital output module engineered for Honeywell TPS (Total Plant Solution) and Experion PKS control systems. As a key control execution component in industrial automation, it converts digital control signals from the system into discrete output signals to drive field devices—such as solenoid valves, pumps, fans, and indicator lights. Widely applied in oil & gas, petrochemical, manufacturing, and power generation industries, this module ensures reliable equipment control, laying the foundation for stable industrial process operation.
Equipped with optically isolated channels, surge protection, and overload detection, the TK-ODD321 delivers strong anti-interference performance and safe operation under harsh industrial conditions (electromagnetic interference, voltage spikes, and load anomalies). It complies with IEC 61131-2 and UL 508 standards, ensuring seamless integration with Honeywell’s control systems and meeting the strict safety and reliability requirements of industrial sites.

3. Key Features
3.1 High-Density & Configurable Output
32 isolated channels in a compact form factor maximize control cabinet space utilization, suitable for large-scale equipment control scenarios like petrochemical plant pump stations. The module supports both sink (NPN) and source (PNP) output modes, configurable via software to adapt to different types of field actuators, enhancing application flexibility.
3.2 Robust Protection & Reliability
Each channel is equipped with overload and short-circuit protection, automatically limiting current when faults occur to avoid module damage. Optically isolated channels and surge protection (IEC 61000-4-5) effectively suppress electromagnetic interference and voltage spikes, ensuring stable output signals in noisy industrial environments like power generation workshops.
3.3 Fast Response & Comprehensive Diagnostics
With a response time of ≤1 ms, the module enables rapid control signal execution, critical for time-sensitive processes like packaging machinery sorting and emergency shutdown systems. Built-in diagnostics monitor channel faults, load anomalies, and power supply status in real time, transmitting alerts to the control system for proactive troubleshooting.
