Backplane Bus Communication Velocity & I/O Processing
The module maintains synchronized input scanning across the Series 90-70 backplane bus, supporting deterministic backplane bus communication velocity during high-density signal transitions. Software configuration capabilities provide channel parameter assignment and I/O density scaling across the 32 input points, eliminating the need for physical jumpers or DIP switch settings.
Frequently Asked Questions
Q: What current load does the IC697MDL250 place on the 5 VDC backplane supply?
A: The module draws 0.35 A from the internal +5 VDC backplane power bus.
Q: What is the channel group isolation configuration on this module?
A: The 32 discrete input points are divided into 4 optically isolated groups, containing 8 points per group.
Q: What is the input filter delay response time for signal conditioning?
A: The module utilizes a standard 20 ms input filter delay time for field signal debouncing.
Field Installation Guidelines
- Baseplate Mounting: De-energize system power before inserting the module into any available Series 90-70 baseplate slot, pressing firmly until the module backplane connectors seat fully into the bus frame.
- AC Wiring Connections: Wire 120 VAC field inputs to the removable terminal block, ensuring each isolated group of 8 points receives its dedicated neutral and supply line connections.
- Separation of Lines: Maintain clear physical separation between high-voltage 120 VAC input lines and low-voltage DC communication or logic cabling inside the wireway.
- Shield Grounding: Secure field wiring cable shields and baseplate grounding studs directly to a low-impedance master enclosure ground point to prevent noise coupling.
