Technical Specifications Matrix

Hardware Installation and Terminal Options

• Backplane Mounting: Slides directly into any universal backplane slot within an RX3i system running CPU firmware version 5.5 or later.
• Terminal Block Compatibility: Requires separately purchased terminal blocks, including the standard box-style IC694TBB032, spring-style IC694TBS032, extended box-style IC694TBB132, or extended spring-style IC694TBS132.
• Firmware Management: Supports seamless system upgrades in the field using the WinLoader software utility.

Diagnostics and System Monitoring

The IC695ALG306 features comprehensive hardware self-diagnostics that track critical system health markers. It reports fault statuses for RAM failures, watchdog timer exceptions, and flash memory verification errors directly to the controller. Furthermore, CJC temperatures are mapped as separate input channels, allowing operators to detect sensor drift or local terminal block temperature anomalies immediately via the programming software.

Target Applications and System Compatibility

Engineers integrate this module into high-temperature industrial processes, chemical reaction vessels, power generation turbine monitoring, and heavy metallurgical furnace controls. It pairs exclusively with RX3i universal backplanes and requires matching firmware architectures to ensure uncompromised data throughput and signal integrity.

Frequently Asked Questions

Question: How does the IC695ALG306 module handle Cold Junction Compensation (CJC) reporting within the control program?

Answer: The module tracks CJC temperature values and reports them as separate input channels with a fixed 20 Hz update rate, enabling real-time thermal reference monitoring in the application logic.

Question: What steps are necessary if a firmware upgrade fails during field maintenance on this unit?

Answer: Technicians must re-establish a stable connection via the WinLoader utility, verify the communication baud rate, and reinitiate the binary transfer package while keeping the backplane power uninterrupted.

Question: Why would an unexpected open-circuit or over-range condition trigger a fault flag on a specific channel?

Answer: This behavior typically indicates a broken thermocouple wire, an oxidized terminal connection, or an input signal exceeding the configured ±150 mV or ±50 mV threshold limits.

Question: Can standard non-extended terminal blocks be used interchangeably with extended versions on this hardware?

Answer: Yes, both standard blocks like the IC694TBB032 and extended variants fit the module footprint, though extended styles offer extra physical routing space for heavy-gauge shielded thermocouple wiring.

Question: What purchasing criteria should engineers consider when selecting replacement modules for aging RX3i architectures?

Answer: Buyers must verify that the host CPU runs firmware version 5.5 or newer and confirm that the backplane power supply can support the additional 3.3V current draw requirements before installation.
