9097-1126 Reliance Electric PRO-400K Stored Motion Profile Controller

The 9097-1126 is a PRO-400K stored motion profile controller designed and manufactured by Reliance Electric (now part of Rockwell Automation). It is a high‑performance, standalone motion controller engineered for precise, repeatable positioning and speed control in industrial automation systems. This model is a legacy, discontinued unit; available stock is limited to new surplus, professionally refurbished, and tested used components from specialized industrial suppliers.

Description

9097-1126 Reliance Electric PRO-400K Stored Motion Profile Controller

Product Overview

Model Nomenclature

9097: Base series code for Reliance Electric’s motion control platform.
1126: Specific configuration identifier for the PRO-400K controller, denoting firmware revision, memory capacity, and I/O configuration.

Core Functionality

The PRO-400K controller stores up to 16 predefined motion profiles in non‑volatile flash memory. Each profile includes adjustable parameters for acceleration, deceleration, speed, and target position. It executes stored profiles on command via discrete I/O or serial communication, enabling standalone operation without a host PLC. Ideal for repetitive, high‑precision motion tasks.

Electrical Specifications

Input Voltage: 24 VDC ±10% (20.4–26.4 VDC)
Operating Current: 300 mA maximum
Control Outputs: Opto‑isolated, 24 VDC, 500 mA per channel (for drive enable, start/stop, fault reset)
Feedback Inputs: Quadrature encoder (A/B/Z) up to 500 kHz, TTL/RS‑422 compatible
Communication: RS‑232 serial port (9600–19.2 kbps) for programming and monitoring
Memory: 128 KB flash (profile storage), 8 KB RAM (runtime)
Isolation: 500 VAC dielectric strength between I/O and power circuits

Mechanical & Construction

Enclosure: Rugged aluminum chassis, industrial painted finish, rated IP20
Mounting: Panel‑mountable with standard 4‑hole pattern (160 mm × 100 mm)
Dimensions: 180 mm (W) × 110 mm (H) × 45 mm (D)
Weight: Approx. 1.8 kg (4.0 lbs)
Terminals: Screw terminals for power, I/O, encoder, and serial connections; clearly labeled
LED Indicators: Power, Run, Fault, Profile Active, Encoder Status

Key Features

Stored Profile Operation: Executes up to 16 preprogrammed motion sequences without host control
High‑Resolution Feedback: Supports quadrature encoders for accurate position/speed regulation
Opto‑Isolated I/O: Ensures noise immunity and electrical safety in industrial environments
Non‑Volatile Memory: Profiles retained without power; easy to update via serial port
Flexible Triggering: Profile start via discrete input, serial command, or external sensor
Comprehensive Protection: Overvoltage, undervoltage, overcurrent, and encoder fault detection

Applications

Industrial Automation: CNC machinery, automated assembly lines, packaging equipment
Material Handling: Conveyors, indexing tables, pick‑and‑place systems
Precision Positioning: Robotics, laser cutting, engraving, and inspection systems
Retrofit Projects: Ideal for upgrading legacy Reliance Electric drives (e.g., Max‑400, FlexPak 3000)

Lifecycle & Warranty

Production Status: Original manufacturing discontinued by Reliance Electric
Available Conditions: New surplus (factory sealed), refurbished (tested, calibrated, cleaned), tested used (fully functional)
Warranty: 12–24 months from authorized suppliers; new surplus may carry extended coverage
Testing: All units undergo 8‑hour dynamic testing, verifying profile execution, feedback accuracy, and protection circuits

Compatibility

Drives: Reliance Electro‑Craft Max‑400, FlexPak 3000, and compatible third‑party servo drives
Motors: Brushed/brushless DC servo motors with quadrature encoder feedback
Programming: Configured via Reliance Electric’s PRO‑400K software (DOS‑based) or third‑party tools
