The TK-OAV081 is a high-precision hardware component configured as an 8-channel high-level Analog Output Module within the Honeywell C200 / Experion LS and Experion PKS I/O (CIOM-A) hardware platform ecosystem. This module manages the transmission of precise control signals to final control elements, providing highly configurable dual-mode functionality capable of driving either continuous current loops or voltage potentials simultaneously. Built with strict galvanic isolation between user field wiring and the internal supervisory control system backplane, it safeguards system integrity from common-mode electrical noise and spikes. The integration of high-resolution digital-to-analog converters ensures smooth, repeatable control loops for variable-speed drives, positioners, and continuous valve actuators running in critical processing environments.

Maintain low-impedance electrical bonding between the C200 system chassis and the primary master instrument grounding grid. Run analog signal lines using twisted-shielded instrumentation pairs, ensuring that the shield drain wires are terminated strictly at one designated grounding rail outside the local module rack to alleviate ground loop induced noise.
The solid-state internal arrays are vulnerable to degradation or complete destruction from electro-static events. Field personnel must wear an approved, snug-fitting static-dissipative wrist strap attached to an established ground prior to handling the module casing, terminal blocks, or setting interior jumpers.
The module features a maximum continuous power dissipation of 6.9 W. Arrange rack assignments to leave uniform spaces or respect standard spacing guidelines, confirming that cold-air flow paths across the vertical rack slots are fully open and ambient cabinet temperatures stay stable.
Confirm that external field-side loads do not cross the internal output drive limits before putting channels into operation. Ensure that active current loops have a total loop impedance falling inside the 0 to 750 Ohm window, and that voltage circuits feed high-impedance devices rated greater than 2000 Ohm.
What types of output signals can this module generate?
Each of the eight channels is capable of producing software-assigned voltage signals up to ±10.4 V or current loops spanning 0 to 21 mA.
What is the digital conversion resolution for voltage and current commands?
The module operates with a resolution of 320 uV per count for voltage configurations and 650 nA per count for current configurations.
What physical block is needed to complete field-side wiring loops?
This module utilizes the model TC-TBNH 20-position terminal block for physical terminal matching.
How does the hardware protect itself against a direct short-circuit in the field?
The channels incorporate electronic limiters that immediately clamp the output current to 21 mA or less under short-circuit parameters.
What is the channel refresh interval for control updates?
The conversion and updating interval across all eight integrated channels is rated at 25 ms.
What is the exact transient isolation capability between field loops and backplane logic?
The module architecture is factory-verified to withstand a user-to-system isolation test parameter of 2550 VDC for 1 second.
How long does it take for the signal to stabilize after a setpoint shift?
The output settling time is less than 2 ms to hit 95% of the final target value when operating into a resistive load profile.
What level of precision loss should be expected from temperature swing offsets?
The typical thermal offset drift is specified at 50 uV/Celsius for voltage installations and 100 nA/Celsius for current systems.
Can individual channels handle accidental back-feeding of external control voltages?
The module is protected against continuous overvoltage events up to 24 VAC/VDC at standard room temperatures.
What is the unboxed net weight of the physical module assembly?
The individual, unboxed hardware module has a net weight of exactly 0.5 Kg.
