Incremental Encoders Wiring
Original instructions
About us
Introduction
Use the BMXFTB2800 or BMXFTB2820 28-pin terminal block to connect incremental encoders to the module.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
  • Ensure that the turbomachinery is stopped while connecting or disconnecting the module or the terminal block.
  • Connect or disconnect the terminal block with sensor and pre-actuator voltage switched off.
Failure to follow these instructions will result in death or serious injury.
The following types of incremental encoder can be connected to respectively:
RS422 Type Wiring

Supply Tracking Line Driver Type Wiring
To prevent from interference, you must short wire the MPU interface when using supply tracking line driver. Otherwise detected interference may cause unexpected measured values.
WARNING
UNEXPECTED VALUES
Be sure to short wire the MPU interface when using supply tracking line driver.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
