🔌 Honeywell TK-OAV081 Analog Output Module – Model PN-15765 FW Rev: 1.5
The Honeywell TK-OAV081 analog output module is a vital component in advanced PLC-based process control systems. Identified by part number PN-15765 and firmware revision 1.5, this module is specifically engineered to deliver high-performance analog signal output in demanding industrial environments. It converts digital control signals into precise analog voltages or currents, supporting accurate manipulation of field devices such as valves, actuators, and drives. Its robust design makes it suitable for continuous operation in process industries including oil and gas, chemicals, power generation, and manufacturing automation.
⚙️ Technical Highlights
The TK-OAV081 module offers 8 independent analog output channels, each capable of transmitting standard voltage or current signals, typically in the 0–10V or 4–20mA range. These channels are electrically isolated to protect both the module and connected devices from electrical interference or overload conditions. The unit supports high-resolution DACs (digital-to-analog converters) to ensure smooth and accurate signal transitions, which is critical for process stability. With firmware version 1.5, the module includes enhanced calibration routines and improved response times, supporting faster signal updates and better loop control accuracy.
The module is equipped with status LEDs for channel diagnostics, allowing operators and technicians to quickly identify fault conditions or signal losses. Communication with the main controller is handled through a dedicated backplane interface, which ensures fast data exchange and tight synchronization with the control logic. The module features a DIN rail-mountable enclosure, optimized for industrial control cabinets. It also offers hot-swap capability, minimizing downtime during maintenance or upgrades. Power supply requirements and signal conditioning circuitry are integrated into the board layout, reducing the need for additional hardware.
🧩 Application and Integration
Honeywell’s TK-OAV081 is compatible with Experion PKS and other Honeywell DCS/PLC platforms. It integrates easily into existing configurations, allowing plant operators to scale their analog output capacity without modifying system architecture. The module’s flexibility supports both control and monitoring applications, such as regulating burner positioning in boilers, controlling dampers in HVAC systems, or setting pump speeds in chemical dosing units. Firmware updates are supported via the system configuration tool, allowing long-term support and enhancements to performance.
