INPUT SPECIFICATIONS

Sensor Excitation
Voltage
: 12 V DC ±10 %
Current: 15 mA
Current limiting circuit: Approx. 30 mA
INPUT RANGE: 0 – 100 kHz, 0 – 10 kHz, 0 – 1 kHz, 0 – 100 Hz, 0 – 10 Hz, 0 – 1 Hz, 0 – 0.1 Hz
Minimum pulse width requirement: 5 μsec. for both ON and OFF
DETECTING LEVEL
Detecting level
: 15 – 100 %
(of operational voltage range across the terminals)
Factory setting: 50 % (programmable using the R3CON PC Configurator software)
Note 1. Each channel has three sets of input terminals.
Input terminal 1: 2 – 5, 7 – 10, 12 – 15, 17 – 20
Input terminal 2: 3 – 5, 8 – 10, 13 – 15, 18 – 20
Input terminal 3: 4 – 5, 9 – 10, 14 – 15, 19 – 20
Note 2. Gain 1 or Gain 2 selectable with the side DIP SW.
Note 3. Measured as 0 % below 15 % of the range.
Open Collector (input terminal 3, gain 1)
Sensor excitation: 12 V DC
Pull-up resistance: 20 kΩ (shorted across 1 – 3, 6 – 8, 11 – 13, 16 – 18 respectively)
ON voltage: ≤ 1.5 V (≤ 2 kΩ recommended)
OFF voltage: ≥ 2.5 V (≥ 20 kΩ recommended)
(Set detecting level 50 % when the saturation voltage is not greater than 0.8 V, set 70 % when the saturation voltage is between 0.8 to 1.5 V.)
Voltage Pulse (input terminals 1 and 2)
Waveform: Square, sine or similar waveforms
Input impedance: 100 kΩ minimum at input terminal 1
20 kΩ minimum at input terminal 2
Operational voltage across the terminals:
0 – 50 V (input terminal 1, gain 1)
0 – 25 V (input terminal 1, gain 2)
0 – 12 V (input terminal 2, gain 1)
0 – 6 V (input terminal 2, gain 2)
Threshold: Pulse logic is detected by comparing input pulse voltage and the detecting level. Detecting ‘Rise’ or ‘Sink’ can be switched by using the R3CON PC Configurator software; factory setting ‘Rise’)
