Hardware Specifications

Cold Junction Compensation and Backplane Synchronization

• Cold Junction Compensation (CJC): Features onboard CJC processing algorithm support and external RTD reference integration to correct temperature measurement gradients across thermocouple terminations.
• 4-20 mA Loop Processing: Accommodates 4-20 mA loop inputs and high-resolution voltage acquisition across 8 software-configurable channels arranged in two isolated 4-channel banks.
• Backplane Bus Communication Velocity: Interfaces directly with the PCI backplane bus of the RX3i Universal Backplane, delivering deterministic high-speed analog scan updates to the CPU.
• Firmware Flash Compatibility: Fully compatible with RX3i CPU firmware routines via Machine Edition programming software for parameter configuration and diagnostics.

Frequently Asked Questions

Q: How are 4-20 mA current signals wired on the IC695ALG600-DD without external shunt resistors?

A: The module features built-in software-selectable internal precision burden resistors for current measurement ranges, eliminating the need for external shunt components.

Q: Can channels within the same module be configured for different input signal types simultaneously?

A: Yes, each of the 8 channels can be individually software-configured in PACSystems Machine Edition for distinct sensor types, including thermocouples, RTDs, volts, or milliamperes.

Q: Is hot-swapping supported for this module within an RX3i Universal Backplane?

A: Yes, the module supports Hot Swap (Insertion/Removal under Power) when installed in an RX3i Universal Backplane, allowing replacement without interrupting backplane power to adjacent modules.

Field Installation Guidelines

• Module Mounting: Align the card with the target slot rails in an RX3i Universal Backplane (IC695 series) and firmly seat the PCI backplane connector until top and bottom latches secure.
• Shielded Wiring: Connect analog signal leads using twisted-shielded pair cables. Connect cable shields to the carrier ground frame or dedicated terminal block to maintain noise immunity.
• CJC Sensor Placement: When utilizing thermocouple inputs, install cold junction compensation sensors at the field terminal strip as specified in the PACSystems wiring manual.
• Grounding Practice: Ensure the RX3i backplane chassis maintains a low-impedance connection to cabinet earth ground to protect sensitive 16-bit A/D conversion circuitry from common-mode noise.
