INPUT SPECIFICATIONS
■ Sensor Excitation
Voltage: 12 V DC ±10 %
Current: 15 mA
Current limiting circuit: Approx. 30 mA
■MAXIMUM FREQUENCY: 100 Hz
Minimum pulse width requirement: 5 msec. for both ON and OFF
■DIVIDING RATIO: 1 – 50000 (programmable using the R3CON PC Configurator software;
factory setting ‘1’)
■COUNT RANGE: 1 – 100 000 000 (0 at reset)
Min. and max. pulse range selectable using the R3CON PC Configurator Software. Refer to the R3CON Users Manual for detailed information.
Count at overflow: Reset and restart at ‘1.’
Recount start value at over flow: 0 or 1
Maximum count: 1000 – 800 000 000
■DETECTING LEVEL
Detecting level: 15 – 100 %
(of voltage across the terminals)
Factory setting: 50 % (programmable using the R3CON PC Configurator software)
Current limiting circuit: Approx. 30 mA
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.
■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’)
■ 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)

INSTALLATION

Operating humidity: 30 to 90 %RH (non-condensing)
Atmosphere: No corrosive gas or heavy dust
Mounting: Installation Base (model: R3-BSx)
Weight: 200 g (0.44 lb)

PERFORMANCE
Data allocation: 8
Current consumption:
80 mA (with no load at the sensor excitation)
130 mA (15 mA at each excitation)
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength: 1500 V AC @ 1 minute (input 1 to input 2 to input 3 to input 4 to internal bus or internal power)
2000 V AC @ 1 minute (power input to FG; isolated on the power supply module)

FUNCTIONS
■ MANUAL COUNT RESET
1) Remove Network Module or its cables and interrupt communication with other devices.
2) Turn ON the Count Reset SW.
3) Return the module to the base and turn the power supply on.
4) ERR LED turns on and the module starts resetting its counter. When the resetting is complete, the LED light turns to green. DO NOT remove the power while the red light is on.The RUN LED starts blinking at the same time.
5) After the green LED is confirmed, turn the power supply off.
6) Turn OFF the Count Reset SW.
7) Return the Network module onto the base and turn the power supply on.
Note: Count Reset SW must be turned OFF after this procedure because the module does not start counting with ON state.
