45MLA Controller
IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.
Description
The Allen-Bradley 45MLA light array controller drives the
photoelectric elements in the light arrays, which are essentially a
series of transmitted beam pairs. Five versions of the controller are
available, each offering a different communications platform that
can be selected to function with a range of PLCs.
• 45MLA controller analog model
Cat. No. 45MLA-CTRL-ALG
• 45MLA controller basic model Cat. No. 45MLA-CTRL-BSC
• 45MLA controller I/O model Cat. No. 45MLA-CTRL
• 45MLA controller RS485 Cat. No. 45MLA-CTRL-485
• 45MLA controller CAN Cat. No. 45MLA-CTRL-CAN
The controller includes numerous application features, allowing
for customization to the many applications. For instance, the I/O
module can be used to configure up to four separate sensing
zones with independent outputs and overhang/over-height
detection. The basic model has a single on/off output for use in
discrete applications. The analog output model offers either a
4…20 mA current or 0…10V output proportional to target height,
width, or position. The network communication models (RS485
and CAN) can be used to communicate precise height readings
and individual beam status.
Features
• External controller for 45MLA measuring light arrays
• Height measuring capability
• Fast reaction time and measurement speed
• Configurable over-height and overhang outputs
• Analog model offers either 4…20 mA or 0…10V output
proportional to target height, width, or position
• Basic models offers single discrete output for use in on/off
applications
• I/O model features teach button for setting up four height
“zones” with individual outputs
• RS485 and CAN communication models provide extra
functionality, including:
- Connection to RS485 or CAN networks (by model)
- Detailed height information
- Individual beam status
