Allen‑Bradley 45MLA-CTRL-IP00 Measuring Light Array CAN Controller

Product Overview

Core Specifications

• Power supply: 10–30 VDC industrial control power
• Communication interface: CANopen (CAN bus, IP00 model dedicated)
• Sensor connection: Dual RJ45 ports for light array emitter & receiver cascading
• I/O terminals: Removable spring screw terminal block, supports PNP/NPN logic switchable via jumpers
• Built-in teach button: One-click calibration for measuring range and detection thresholds
• Housing protection: IP54 transparent cover enclosure, wall/din rail mountable
• Status indicators: Power, communication, beam detection, fault diagnostic LEDs
• Operating temperature: -20 ℃ ~ +55 ℃
• Certifications: UL, CE industrial automation certified
• Supported array stroke: 10 mm pitch light matrices up to 1200 mm total height
• Signal output: Configurable discrete zone outputs for over-height, missing part, edge detection

Main Functions

1. Drive and read all light beam signals from 45MLA measuring light arrays, calculate real-time object height, width and offset position
2. Process multi-zone detection logic to identify overhang, overflow, missing workpieces and position deviation
3. Transmit high-precision measurement values, beam status and fault codes to PLC via CANopen bus
4. Provide configurable discrete digital outputs for direct trigger of alarms, reject gates or sorting actuators
5. Support cascading multiple light array segments to extend overall detection measuring range
6. Store calibrated measurement parameters internally after teach setup, no repeated re-calibration after power cycle

Key Advantages

• CANopen bus communication realizes long-distance stable data transmission, suitable for distributed production line inspection stations
• Transparent enclosure allows real-time visual checking of internal wiring and LED diagnostic status without opening the housing
• One-touch teach function simplifies on-site calibration without complex software configuration
• Flexible PNP/NPN input/output logic matches all mainstream PLC control systems
• Compact integrated design combines sensor driving, signal calculation and network communication in one unit to reduce cabinet wiring complexity
• Multiple built-in fault self-diagnosis functions quickly locate broken emitters, cable disconnection and communication failures
