Backplane Bus Communication Velocity and Firmware Compatibility
The IC697ALG440 module transfers digitized 16-bit process parameters directly across the VME-based Series 90-70 backplane bus, preserving high backplane bus communication velocity during intensive execution cycles. Channel data updates every 2.4 ms without imposing processing overhead on the host CPU. Internal flash firmware compatibility guarantees seamless address mapping and hardware handshake protocol synchronization across IC697CHS750, IC697CHS782, and IC697CHS790 chassis models. Furthermore, optical isolation barriers protect internal backplane logic from ground loops, field surges, and industrial electrical noise.
Frequently Asked Questions
Q: Can the IC697ALG440 analog input module be inserted or removed while the rack is powered?
A: No, field technicians must switch off backplane power prior to inserting or extracting the module. Hot-swapping is strictly prohibited on Series 90-70 VME backplanes to prevent hardware damage and backplane communication disruption.
Q: How does the module handle 4-20 mA current loop inputs?
A: The module incorporates internal 250 ohm precision shunt resistors to convert incoming 4-20 mA field currents into voltage signals prior to high-resolution 16-bit Successive Approximation Analog-to-Digital conversion.
Q: Is the IC697ALG440 directly compatible with PACSystems RX3i chassis platforms?
A: No, the IC697ALG440 utilizes the Series 90-70 VME backplane form factor and pin assignment architecture, rendering it non-interchangeable with RX3i backplane racks.
Field Installation Guidelines
Align the IC697ALG440 module circuit board with the top and bottom card guides of the designated Series 90-70 rack slot. Slide the board firmly inward until the rear DIN connectors mate fully with the backplane logic plane, then engage upper and lower mechanical locking levers to secure the module assembly.
Route field signal wiring through dedicated low-voltage wire ducts, maintaining adequate physical isolation from AC motor leads and high-power switching cables. Use shielded twisted-pair conductors for all 4-20 mA analog input loops to prevent electromagnetic noise induction.
Connect wire cable shields to the cabinet ground bar at a single termination point near the entry panel. Ensure the enclosure maintains forced-air ventilation or convection cooling pathways to keep ambient operating temperatures within the specified 0 deg C to +60 deg C range.
