Hardware Specifications

Profinet and EtherNet/IP Deterministic Networks

The 1760-L18BWB-EX operates as a compact programmable logic controller utilizing internal firmware logic execution routines. It supports local I/O expansion scaling to accommodate additional discrete sensors and actuator control loops. The internal real-time clock enables time-stamped event logging and scheduled automation sequences without requiring external hardware modules. Communication interfaces support peripheral programming terminals and basic panel-mounted operator displays for real-time parameter modification.

Frequently Asked Questions

Q: Can the 1760-L18BWB-EX controller support analog inputs directly out of the box?

A: No, this specific base model features 12 digital inputs and 6 relay outputs. Analog signal processing requires the attachment of compatible expansion modules to the system bus.

Q: What is the maximum switching current capacity for the onboard relay outputs?

A: The onboard relay outputs are rated for standard industrial control loads, typically up to 2 A per channel at resistive loads, subject to operating temperature constraints.

Field Installation Guidelines

• DIN-Rail Mounting: Secure the controller vertically onto a standard 35 mm DIN rail, leaving adequate clearance above and below the housing for natural convective airflow.
• Power Wiring: Connect a regulated 24 VDC power source to the designated supply terminals. Verify voltage levels before closing the circuit to prevent internal component damage.
• Input/Output Shielding: Route low-voltage digital input lines separately from high-voltage power cables and motor drives to reduce electromagnetic interference and signal corruption.
• Grounding: Establish a low-impedance ground connection from the unit ground terminal to the main enclosure backplate using heavy-gauge copper wire.
• Terminal Torque: Tighten all screw terminal blocks to the manufacturer-specified torque rating to ensure reliable electrical contact under high-vibration conditions.
