Allen-Bradley controls & components

Logix controllers combine machine control, communications and I/O in the Studio 5000 environment. Select by the application and exact catalog number, not appearance alone.

• Controller variants provide different motion, capacity and safety capabilities.
• Back up the application and verify firmware, I/O and network compatibility before migration.

A modular distributed-I/O system combines the network adapter, terminal bases and signal modules. Diagnose field wiring and power as well as the I/O electronics.

• Family includes digital, analog and specialty I/O; modules offer one to eight points by type.
• Standard POINT I/O and POINT Guard safety I/O require different selection and validation.

Servo-drive systems integrate machine motion with Logix control over EtherNet/IP. Axis power, bus supply, motor feedback and the control application must be reviewed together.

• Single- and dual-axis inverter options are available within the system.
• Installed safety options and firmware must be identified; no universal drop-in replacement is implied.

Adjustable-speed motor control supports varied machine loads. The VFD must match the motor, supply, load and existing control design.

• Review nameplate voltage, motor current, I/O and communication requirements.
• Fault history and saved parameters help separate drive faults from motor or machine-side problems.
