Analog Signal Processing and HART I/O Characteristics

The IS220PHRAH1A performs analog signal conversion through integrated ADC and DAC circuits. The 16-bit analog-to-digital converter supports input measurement processing, while the 14-bit digital-to-analog converter generates current output signals. Input filtering functions provide selectable noise suppression at 3 Hz, 6 Hz, and 12 Hz to support signal conditioning requirements.

The module supports channel-level analog processing with common mode rejection capability of 60 dB at 60 Hz and a common mode voltage range of +/-5 V. The 4-20 mA output channels support external loads up to 800 ohm.

Frequently Asked Questions

Q: What analog input signals can the IS220PHRAH1A process?
A: The module supports 4-20 mA DC current inputs and +/-5 V DC voltage inputs on configured analog input channels.

Q: What conversion resolution is provided for signal processing?
A: Analog input conversion is performed using a 16-bit ADC, and analog outputs use a 14-bit DAC converter.

Q: How does the module connect to the Mark VIe control system?
A: The IS220PHRAH1A communicates through the Mark VIe backplane using TCP/IP-based communication.

Field Installation Guidelines

Install the IS220PHRAH1A module in the designated Mark VIe rack position and verify mechanical engagement with the backplane connector before applying power.

Use shielded instrumentation cables for analog signal wiring. Connect cable shields according to site grounding standards and avoid routing low-level analog cables parallel to high-current power conductors.

Verify terminal board compatibility before field wiring. Confirm input signal polarity, channel assignment, and current loop configuration before commissioning.

Maintain proper separation between analog signal wiring and switching or motor drive circuits to reduce electromagnetic interference. Perform insulation checks and signal validation after installation.
