Honeywell TK-OAH061 Analog Output Module

Overview

The Honeywell TK-OAH061, also cataloged as the TK-OAH061 Analog Output Module, provides six isolated current output channels for direct 4-20 mA control signal generation within Honeywell Experion PKS C200/C300 I/O platforms.

Hardware Specifications

HART Loop and Channel Isolation Characteristics

The Honeywell TK-OAH061 operates as a process control output interface for analog field circuits. It generates current signals for actuators, valve positioners, and variable speed control devices through configured 4-20 mA loops.

Furthermore, the module incorporates channel-to-channel isolation to reduce interference between independent output circuits. The isolated design separates field wiring conditions from internal controller electronics and supports stable analog signal transmission in Experion PKS I/O architectures.

The TK version includes conformal coating protection for operation in environments containing humidity, corrosive contaminants, or airborne industrial particles. The analog output channels use a 13-bit digital-to-analog conversion structure to provide controlled current output regulation.

Frequently Asked Questions

Q: Does the TK-OAH061 support direct HART communication?
A: The module provides 4-20 mA analog output capability. Available data does not specify integrated HART communication functions for this output module.

Q: What isolation functions are provided by the TK-OAH061?
A: The module provides galvanic isolation between output channels and between user field connections and system electronics.

Q: What terminal connection hardware is required for installation?
A: The module uses the TC-TBNH 20-position terminal block for field wiring connection.

Field Installation Guidelines

• Install the TK-OAH061 in the designated Honeywell Experion PKS I/O carrier according to the system hardware configuration manual.
• Verify module addressing and controller configuration before applying field power.
• Use shielded instrumentation cables for analog output loops when installed in areas with electromagnetic interference sources.
• Connect cable shields according to site grounding standards to prevent unwanted signal noise.
• Separate analog signal wiring from high-voltage power cables and high-current motor circuits.
• Confirm field device input impedance and current loop requirements before commissioning.
• Inspect terminal connections for correct polarity and secure mechanical fastening before system startup.
