Types and Number of Connectable Sensor Amplifiers
 Number of Connectable Sensor Amplifiers
* Up to 11 sensor heads can be connected by adding a head connection board to the
main unit.
The DL-PD1 can connect to multiple sensor amplifiers (a single main unit and multiple
expansion units) which support D-bus. "D-bus" is the name of KEYENCE's wiring-saving
system for sensor amplifiers.
Different types of sensor amplifiers with D-bus support can be connected to a single DL-
PD1 unit.
How many and what types of sensor amplifiers can be connected depends on the
sensor amplifiers or units to be connected. Please inquire for details.
