Related Technical Topics
- Bank Sizing & Power Supply — Each 1769 bank supports up to 8 I/O modules plus the end cap (1769-ECR/ECL). Total 5V and 24V backplane current must not exceed the power supply rating. Consult the module datasheet for each entry’s current draw; add 10% margin.
- End Cap Placement — The right-most module in every bank must be followed by a 1769-ECR end cap (or 1769-ECL on the left of the leftmost bank). End caps terminate the backplane — without them, the controller will fault on power-up.
- Bank-to-Bank Expansion Cables — Use 1769-CRL1 (305 mm / 1 ft) or 1769-CRL3 (914 mm / 3 ft) cables to extend the backplane between banks. Max system = 3 banks (controller + 2 expansion), or 2 banks for MicroLogix 1500.
- Distance from Controller — The first bank contains the CompactLogix controller; expansion banks attach to its right. Keep backplane cable runs short and away from high-voltage wiring to preserve signal integrity.
Source: Module-specific specifications are compiled from Rockwell Automation Publication 1769-TD006I-EN-P — CompactLogix 5370 / Compact I/O Technical Data (March 2024) together with the module’s individual product specification sheet.
