Allen-Bradley 1760-L18BWB-EX Pico Controller Module
The Allen-Bradley 1760-L18BWB-EX, also cataloged as the 1760-L18BWB-EX Pico Controller, operates as a dedicated hardware component for compact logic execution within Allen-Bradley Pico control systems. The unit integrates 18 total embedded I/O points (12 digital 24 VDC inputs and 6 electromechanical relay outputs) powered by a 24 VDC main supply circuit. Featuring an integrated real-time clock for time-triggered control routines, the module provides direct physical/electrical execution for local control loops and supports downstream I/O expansion modules.

Backplane Bus Communication & Deterministic Processing
The Allen-Bradley 1760-L18BWB-EX manages internal expansion bus communication velocity by synchronizing onboard discrete input scans directly with connected expansion modules. Firmware flash compatibility across the Pico hardware platform maintains deterministic instruction execution, ensuring rapid relay output coil updates based on digital input transitions. The controller scales I/O density while preserving execution timing and cycle updates across localized logic block topologies without requiring external bus repeaters or secondary processors.
Frequently Asked Questions
Q: Does the 1760-L18BWB-EX controller support expansion beyond its 18 onboard I/O points?
A: Yes. The 1760-L18BWB-EX is an expandable model that allows direct physical mounting and connection of Pico expansion I/O modules via its side-mounted expansion interface port.
Q: What type of power source is required to operate the 1760-L18BWB-EX?
A: The module operates on a standard 24 VDC primary power supply. Internal logic processing and input field circuits are powered from this 24 VDC input connection.
Field Installation Guidelines
- Power Isolation: Disconnect main 24 VDC supply power before physically mounting, wiring, or attaching local I/O expansion modules to the 1760-L18BWB-EX controller to prevent electrical damage.
- DIN Rail / Panel Mounting: Mount the unit onto a standard 35 mm DIN rail or secure it to an enclosure backplate using mounting screws. Verify that the DIN rail latch engages firmly to resist mechanical vibration.
- Expansion Port Connection: To attach an expansion module, remove the protective side cover on the right side of the controller and align the expansion interconnect pins straight into the mating socket before latching the housings together.
- Wiring & Grounding: Terminate field input conductors and relay output contact lines at the screw terminal blocks using 22 to 14 AWG copper wire. Route low-voltage 24 VDC signal wiring away from high-voltage AC lines to minimize electromagnetic noise coupling.
