TC-IAH061 | Honeywell | Experion Analog Input

Product Description

The Honeywell TC-IAH061 is an Experion analog input module with six galvanically isolated input channels. It monitors analog signals and provides channel isolation to separate individual input circuits. Furthermore, it supports open-circuit detection for both voltage and current inputs, with different detection responses and times. Its 25 ms update rate covers all six channels.

Key Features

• Six galvanically isolated analog input channels.
• Open-circuit detection for voltage and current signals.
• Selectable detection response according to signal type: upscale for voltage and zero scale for current.
• 0 to 15 Hz channel bandwidth at -3 dB.
• Less than 2.0% of range error under the specified RFI test conditions.
• 25 ms update rate for all six channels.
• Connection through a 20-position TC_TBNH terminal block.

Technical Specifications

Signal Monitoring and Open-Circuit Detection

The TC-IAH061 provides six electrically isolated channels for analog signal acquisition. This arrangement separates the input circuits electrically, helping limit the propagation of electrical disturbances between channels.

In addition, the module uses different responses to identify open-circuit conditions. Voltage inputs produce an upscale reading, while current inputs produce a zero-scale reading. The typical detection times are 5 seconds for voltage and 1 second for current. Therefore, the signal type and expected fault response should be considered when configuring the monitoring logic.

Channel Response and Signal Update

The module has a channel bandwidth of 0 to 15 Hz at -3 dB. Its update rate is 25 ms for all six channels, providing a defined update interval for the complete channel set rather than a separate 25 ms interval for each input.

Furthermore, the specified RFI immunity limits the error to less than 2.0% of range under an electromagnetic field strength of 10 V/m across 27 to 1000 MHz. This specification provides a reference for evaluating signal accuracy under the stated interference test conditions.

Terminal Connection

The TC-IAH061 uses a TC_TBNH 20-position terminal block for field connections. Maintenance personnel should verify the terminal block designation and field wiring arrangement before installation or replacement. The supplied specifications do not define individual terminal assignments or supported signal ranges.

Frequently Asked Questions
