TK-OAH061 | Honeywell | Analog Output Module

Product Description

The Honeywell TK-OAH061 is a six-channel analog output module that provides galvanically isolated current signals for industrial control applications. It supports a 0 to 21.0 mA output range, with 13-bit current resolution and a typical channel update rate of 25 ms for all channels. The module also provides electronic short-circuit protection and defined load-driving limits for current-loop applications.

Hardware Specifications

Current Output and Load Requirements

The TK-OAH061 converts controller output commands into analog current signals for connected field devices. Its six galvanically isolated channels support separate current-output circuits. The specified accuracy applies at 25 deg C and across the 4.0 to 21.0 mA range; it should not be assumed to apply across the entire 0 to 21.0 mA range.

For load selection, the module drives up to 20.0 mA into loads of 500 ohms or less under the stated configuration. Loads of up to 1000 ohms may be possible with alternate field terminations. Confirm the actual termination arrangement and connected load before commissioning.

Protection and Signal Performance

Electronic current limiting restricts the output to 21 mA or less under short-circuit conditions. The module also specifies continuous 24 VAC/VDC output overvoltage protection at room temperature. However, it does not provide open-circuit detection, so an interrupted field circuit cannot be assumed to generate a dedicated open-circuit indication from this module.

The specified settling time is less than 2 ms to reach 95% of the final value with resistive loads. The 25 ms update rate applies to all six channels, so update timing and analog output settling should be treated as separate characteristics when evaluating control-loop response.

Terminal Block and Isolation

The specified connection terminal block is the TC-TBNH, 20-position terminal block. Verify the terminal assignment and field wiring against the applicable module documentation before connecting the six current-output circuits.

The module provides tested isolation between channels and between the user side and system side. Each isolation rating is specified as 2546 VDC for 1 second. These test ratings describe the stated isolation test conditions and should not be interpreted as continuous operating-voltage ratings.

Frequently Asked Questions

Q: How many analog output channels does the Honeywell TK-OAH061 provide?

A: It provides six galvanically isolated current-output channels, each operating within the specified 0 to 21.0 mA output range.

Q: Can the TK-OAH061 drive a 1000-ohm load?

A: Loads of 1000 ohms or less may be supported when using alternate field terminations. The standard stated drive capability is 20.0 mA into loads of 500 ohms or less, so verify the termination configuration before selecting the load.

Q: Which terminal block is specified for the TK-OAH061?

A: The specified terminal block is the TC-TBNH, with 20 positions. Confirm the exact terminal arrangement and wiring requirements using the applicable hardware documentation.
