Request QuoteAllen-Bradley 1769-RTB40DIO — The Allen-Bradley 1769-RTB40DIO is the 40-terminal replacement Removable Terminal Block (RTB) for the embedded digital I/O on CompactLogix 5370 L2 (1769-L2x) controllers — for example 1769-L24ER-QB1B, 1769-L24ER-QBFC1B, and 1769-L27ERM-QBFC1B. It wires the L2 controller’s built-in digital inputs and digital outputs without requiring separate 1769 expansion I/O. Order this replacement when the original RTB is damaged, lost, or when pre-wiring spare-parts kits for fast field swap. The 1769-RTB40AIO is the matching analog-I/O RTB for L2 controllers with embedded analog channels.

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.
