Honeywell TC-OAH061 (96978274-A01) Isolated Analog Output Module 6-Channel

Product Description

The TC-OAH061 (96978274-A01) is a high-performance analog interface module designed for precision control within Honeywell industrial systems. This unit provides six independent, galvanically isolated output channels capable of driving current loops up to 21.0 mA. With a 13-bit digital-to-analog conversion resolution, it ensures highly accurate modulation of field devices such as control valves and variable speed drives. The module is engineered for high-availability environments, featuring an impressive 2546 VDC isolation rating and robust RFI immunity to maintain signal integrity in electrically noisy industrial settings.

Operational Application

The TC-OAH061 (96978274-A01) is typically deployed in process industries where high-density isolation is required to prevent ground loops and protect the central processing unit from field-side transients. Its fast 25 ms update rate makes it suitable for dynamic control loops requiring rapid adjustment of actuators or frequency converters.

Frequently Asked Questions

• Does this module support voltage output modes?

  The TC-OAH061 is optimized for current loop signaling (0-21 mA). For 0-10V applications, a dedicated voltage output module or external precision resistor may be required.

• Is the terminal block included with the module?

  The TC-TBNH 20-position terminal block is a separate accessory often required for installation, though it is compatible with the standard 96mm form factor.
