Technical Data

ParameterMeasured Values
Panel Hole Sizes 67x67mm
Display2×6 Digit 7 Segment display
Count Input 2 x (Max: 7500 Hz, 5-30V)
NPN Selection Connect “npn select” to “+12V” to select NPN sensor for Cp1 and Cp2. Reset input is always PNP. For totem pole or PNP type sensor “npn select” left unconnected.
Sensor Types PNP/NPN proximity switch - NPN/PNP/Totem-pole output encoder
Input Frequency 20, 50, 2500, 7500 Hz Selectable.
Reset Input 10ms (min) , Positive input (PNP only) (5…..30V)
OutputOut1, Out2; 2x Relay (O-NO-NC), 250VAC, 2A, Rezistif Yük 2x Open Collector (NPN), 30V, 100mA max.
Sensor Supply 12VDC, 50mA(max.) unregulated
Supply Voltage 100…240VAC, 50-60Hz
Power Consumption< 8VA
Operating Temperature-20℃….55℃
Operating Altitude < 2000m
Out & Alarm Output Relay (NO + NC), 250VAC, 2A, Resistive load
Sensor FailureMeasurement out of range or Hardware fails, OUT outputting is first OFF for T0f and then ON for T0n periodically. For continuous OFF, enter T0n=0 and T0f=0. For continuous ON, enter T0n=1 and T0f=0. In case of sensor failure, measurement out of range or hardware fails, and alarm type is selected as “SnS”, ALARM output is always ON, otherwise under normal in scale measurement, always OFF
Supply Voltage100 to 240VAC, 50-60Hz
Power Consumption< 6VA
Humidity< 70% (non-condensing)
Altitude< 2000m
