Description
The Honeywell TK-ODK161 (frequently referenced with the standard commercial prefix TC-ODK161) is a high-density, 16-channel Digital AC Output module engineered specifically for Honeywell’s advanced Experion Process Knowledge System (PKS) and C200/C300 controller architectures. Designed to manage high-reliability switching tasks in industrial process automation, this module safely controls AC-powered field loads such as solenoid valves, motor starters, contactors, and alarm indicators with isolated channel protection and robust noise immunity.

⚙️ Installation & Operation Guidelines
- Power Interruption & Safety: Ensure that system cabinet power rails and field AC load supplies are fully de-energized before mounting, removing, or wiring the TK-ODK161 module to prevent electrical shock.
- Chassis & IOTA Seating: Carefully align and slide the module into its designated slot on the compatible Series C Input/Output Termination Assembly (IOTA) backplane, ensuring proper connector engagement.
- Field Wiring Connection: Terminate AC field device lines securely to the matching terminal blocks (such as the 36-position TC-TBCH block), maintaining clear segregation between high-voltage power lines and low-level control signals.
- Diagnostic Check: Energize the controller rack and inspect the front-panel status LEDs alongside Experion engineering software diagnostics to verify proper channel output actuation and communication health.
❓ Frequently Asked Questions (Q&A)
Q1: What is the primary function of the Honeywell TK-ODK161 module?
A1: It serves as a 16-channel digital output module designed to switch and control AC-powered industrial loads (74–265 VAC) safely within an Experion PKS control environment.
Q2: Are the output channels on this module electrically isolated?
A2: Yes, the module features 16 individually isolated output channels designed to protect system backplane electronics from field-side voltage transients and ground issues.
