Backplane Bus Communication Velocity & Firmware Integrity

The IC695ALG608 transfers converted 24-bit analog data over the PCI-based RX3i backplane, maintaining fast bus communication velocity for real-time control routines. Firmware flash compatibility via Proficy Machine Edition (version 5.0 SP3 or later) enables soft configuration of per-channel ranges, scaling limits, and digital filtering options without physical jumper alterations. Built-in autocalibration routines execute on power-up to ensure accurate conversion thresholds across all active channels.

Frequently Asked Questions

Q: What power rails does the IC695ALG608 draw from the RX3i backplane bus?

A: The module draws power directly from both the 3.3 VDC rail (up to 600 mA) and the 5.0 VDC rail (up to 330 mA), with a total maximum power dissipation of 4.83 W.

Q: How are open-circuit conditions handled on current input loops?

A: When configured for 4-20 mA or 1-5 VDC ranges, the module performs open-circuit detection with a maximum response time of 1 second, flagging diagnostic status bits in CPU memory.

Q: Can single-ended and differential configurations be mixed on the same module?

A: The module operates either as an 8-channel single-ended array or a 4-channel differential array based on hardware wiring and module software configuration.

Field Installation Guidelines

  1. Power down the RX3i backplane before installing or removing the IC695ALG608 module to avoid backplane pin erosion or CPU fault generation.
  2. Seat the module firmly into its designated RX3i slot and ensure the retaining levers lock into place on the baseplate.
  3. Terminate shielded twisted-pair cables using standard grounding practices, bonding the cable shield to the ground bar near the terminal block to reject high-frequency electrical noise.
  4. Verify that current loops do not exceed the +/-28 mA continuous limit and voltage lines stay within the +/-60 VDC continuous overvoltage rating.
