4-1 Specifications
*1 Power is supplied from both the sensor amplifier main unit the DL-DN1 is con-
nected to and the network power supply.
*2 "D-bus" is the name of KEYENCE's wiring-saving system for sensor amplifiers.
*3 Depends on the type of sensor amplifiers connected. (Up to 10 sensor units can
be connected to the GT-70A series.)
