The TK-OAV061 is a high-reliability 6-channel analog output module designed for Honeywell HC900 and Experion control platforms. It provides fully isolated voltage outputs to drive field devices such as VFDs, valve positioners, and electrical actuators. Each channel is independently isolated, preventing ground loops and protecting the controller from field-side electrical noise and transients.
Optimized for precision and speed, the module delivers stable 0–10 V signals with a 2 ms loop update time, ensuring responsive and smooth control in dynamic process loops. Its compact form factor, low power consumption, and industrial-grade durability make it suitable for 24/7 operation in sectors including water treatment, power generation, HVAC, and laboratory automation.

Q: Does the TK-OAV061 support 4–20 mA current outputs?
A: No. This module is designed specifically for 0–10 V voltage outputs. For current loop applications, use a module such as TK-HAO081.
Q: Is the isolation between channels or just to the logic side?
A: Each of the six outputs is fully isolated, protecting both the field signals from the internal logic and minimizing interference between channels.
