Backplane Bus Communication Velocity and Firmware Compatibility
The IC697MDL654 executes continuous status scans across its 32 input circuits and transfers discrete byte structures directly to the VME-based Series 90-70 rack, maintaining high backplane bus communication velocity across execution cycles. Optical isolation barriers rated to 1500 VDC isolate field signals from logic circuits, preventing high-voltage surges from entering backplane traces. Internal circuitry maintains seamless firmware flash compatibility across standard Series 90-70 CPU units, enabling deterministic I/O polling, rapid signal detection, and backplane bus synchronization without generating hardware interrupt errors.
Frequently Asked Questions
Q: Does the IC697MDL654 input module support hot-swapping while the baseplate is powered?
A: No, field maintenance personnel must disconnect main backplane power before removing or inserting the module. Hot-insertion into an active Series 90-70 VME slot risks damaging logic components and causing backplane communication trips.
Q: Can the input circuits on the IC697MDL654 accept both sinking and sourcing field wiring configurations?
A: Yes, the module hardware architecture supports both positive logic (sinking) and negative logic (sourcing) 48 VDC signal loops across its input points.
Q: What power rail draws current from the system chassis to power the module logic?
A: The module logic draws a maximum current of 0.3 A (300 mA) directly from the central +5 VDC backplane bus power supply.
Field Installation Guidelines
Align the IC697MDL654 circuit board with the top and bottom card guides of the selected Series 90-70 slot. Slide the card inward until the rear DIN connectors mate fully with the backplane logic plane, then engage top and bottom retaining latches to secure the module.
Terminate field wiring at the removable terminal block assembly. Separate 48 VDC discrete input cabling from high-power AC conductors and motor drives to prevent inductive noise coupling into signal lines.
Connect wire shield drain leads directly to the enclosure master earth grounding bar using short, heavy-gauge copper straps. Ensure unobstructed vertical airflow above and below the rack to maintain operating ambient temperatures within 0 deg C to +60 deg C.
