Interfaces
Product type
DL1000 and DT1000
Inputs/outputs
In1/Q1: digital input, digital output (switchable)
QA/Q2: analog output, digital output (switchable)
Digital Input
Switching type: Source for PNP output (open input corresponds to
the LOW input signal)
Input current: 7 mA (typical), at switching voltage < (Uv - 1 V)
Circuit protection: reverse polarity protected
Switching voltage HIGH: min. 13 V (In1)
Switching voltage LOW: max. 8 V (In1)
Switching functions: deactivate measuring laser, activate align‐
ment laser, preset
Digital outputs
Switching type: push-pull
Continuous current: max. 100 mA
Circuit protection: short-circuit protected
HIGH residual voltage: min. U
v
-4 V
LOW residual voltage: max. 3 V
Capacitive load: max. 100 nF
Inductive load: max. 20 mH
Switching functions: distance to the object, distance switching win‐
dow, switching point for object speed, service functions
Analog output
Current: 4 mA ... 20 mA (working range 3.8 mA … 20.5 mA), can
be freely scaled in distance value range
Current limit values: 3.0 mA and 21.5 mA (NAMUR downtime
information)
Maximum load resistance: (Uv - 7 V) / 21.5 mA (corresponds to
510 Ω … 1,070 Ω at Uv = 18 V … 30 V)
Resolution: 16 bit
