TK-HAO081 Honeywell C200 Analog Output Module

Overview

The Honeywell TK-HAO081, also cataloged as the TK-HAO081 Analog Output Module, operates as a dedicated hardware component for eight-channel analog current and voltage signal generation within Honeywell distributed control systems.

Hardware Specifications

4-20 mA HART Loop and Signal Isolation Characteristics

The module supports conventional analog output operation alongside HART-enabled current output functionality. Channels configured for HART operate exclusively in current mode, maintaining a configurable 4-20 mA signal range within an actual range of 0 to 21 mA. User-to-system isolation is tested at 2550 VDC for 1 second. Non-HART channels support software-configurable voltage ranges of +/-10 V and 0-10 V. The hardware architecture enforces point-to-point HART wiring topologies in compliance with protocol revision 5.7, while multidrop configurations are unsupported. Drive capabilities exceed 2000 ohms for voltage output and range between 50 to 750 ohms for current output configurations.

Frequently Asked Questions

Q: How many analog output channels does the TK-HAO081 provide?

A: It provides eight analog output channels supporting both voltage and current output configurations, with HART-enabled channels operating strictly in current mode.

Q: Does the module support HART multidrop communication wiring?

A: No. The module complies with HART protocol revision 5.7 and supports point-to-point wiring only; multidrop operation is not supported.

Q: Which terminal block is specified for field wiring connections?

A: The module utilizes the Honeywell TC-TBNH 20-position terminal block.

Field Installation Guidelines

• Verify module model compatibility with the target Honeywell control system and I/O chassis prior to physical installation.
• Confirm channel configuration settings for voltage or current modes before energizing field loops, noting that HART channels must use current output mode.
• Terminate field wiring using the designated TC-TBNH 20-position terminal block and verify pin assignments against manufacturer documentation.
• Route analog signal cables separately from high-voltage and high-current conductors to minimize electromagnetic interference.
• Verify field load impedance against specified drive capabilities (greater than 2000 ohms for voltage output; 50 to 750 ohms for current output) before energizing circuits.
• Validate loop continuity and open-loop detection post-wiring, ensuring current output values exceed 0.1 mA for detection functionality.
