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)
