Allen-Bradley 1756-L63 ControlLogix 8 MB Memory Controller

Description

The Allen-Bradley 1756-L63 ControlLogix controller is a programmable automation controller designed for industrial automation systems. It features 8 MB of data and logic memory. The 1756-L63 executes control logic, communicates with I/O configuration devices, and handles Message (MSG) instructions along with OPC/DDE tags via RSLinx software. Nonvolatile memory capabilities are supported via an optional 1784-CF64 Industrial CompactFlash card. Serial RS-232 communications are integrated via an onboard point-to-point interface. The module installs into any slot of a ControlLogix chassis.

Installation Guidelines

• Enclosure: Must be installed in an open-style enclosure appropriate for specific environmental conditions.
• ESD Protection: Wear a grounded wriststrap and avoid touching connectors, pins, or internal circuit components prior to handling.
• Chassis Mounting: Align the circuit board with top and bottom guides inside the chassis, sliding the controller until top and bottom latches lock securely.
• Serial Cable: Limit custom-built RS-232 serial cables to a maximum distance of 15.2 m (50 ft) and connect shielding to both ends.
• Hazardous Location: Do not connect or disconnect cables, batteries, or CompactFlash cards unless power is removed or the area is known to be nonhazardous.
