Allen-Bradley 1785-L40L Modul Prosesor Standar PLC-5/40L

Description

The Allen-Bradley 1785-L40L is a standard processor hardware component operating within the PLC 5 automated architecture to systematically govern and integrate distributed plant machinery networks. This computing core delivers a maximum user memory capacity of 48 Kilowords to coordinate field transactions across a broad spectrum of input and output subsystems. Slot placement requires mounting into the leftmost bay of a standard 1771 I/O chassis layout, executing physical command handling over up to 2048 total I/O configurations. Network tracking is sustained via double Data Highway Plus (DH+) or Remote I/O interfaces, supporting selectable adapter or scanner mode configurations to interface with peripheral hardware devices. The automation module supports detailed addressing layouts including half-slot, single-slot, and double-slot assignments to handle 8-point, 16-point, and 32-point modules seamlessly. For extended processing topologies, it bridges directly with an extended local I/O adapter link, driving structured hardware tracking loops across multi-chassis floor networks.

Features

• Hosts an internal battery-backed static RAM layout for variable storage and operational register execution.
• Direct interface capability with supplementary EEPROM program non-volatile backup cartridges.
• Dual functional communication interface supporting configurable scanner and adapter operational profiles.
• Hardware slot compatibility with intelligent bulletin 1771, 1794, 1746, and 1791 I/O modular blocks.
• Multi-channel electrical isolation protection certified between serial connection logic pathways and relay components.
• Scalable localized scanning matrix extending control routines across remote chassis branches.

Applications

• High-density industrial factory automation lines requiring centralized logic processing with extended local I/O links.
• Distributed monitoring architectures interacting across complex Data Highway Plus (DH+) automation systems.
• Multi-chassis infrastructure processing in manufacturing assemblies.

Installation Guidelines

• Install the central processing assembly exclusively into the designated leftmost slot of the 1771 I/O chassis array.
• Ensure backplane power supplies are properly rated to provide the required 3.3A current load at 5V DC without causing logic rail drops.
• Structure field communication links with correct termination configurations when scanning across the maximum limit of 16 extended local chassis components.
• Maintain the surrounding environmental temperature field strictly within the specified 0 to 60 Celsius boundary limits.
