INPUT SPECIFICATIONS

Excitation: Shortcircuit protection; approx. 440 mA (max.) at

shortcircuit

Maximum frequency: 200 kHz

Maximum count range: -99999999 to +99999999

Minimum pulse width time requirement: 2.5 μsec. for both

ON and OFF

■ Open Collector

Input requirements (Excitation: Sensing)

5 V: Approx. 4 V / 1.0 mA

12 V: Approx. 9 V / 2.3 mA

24 V: Approx. 16 V / 4.7 mA

ON resistance: ≤ 200 Ω

OFF resistance: ≥ 200 kΩ

Detecting level:

1 V (5 V excitation)

2 V (12/24 V excitation)

(Detecting voltage in the internal circuit. For open collector

input, be sure to re-adjust the voltage back to 1 V (5 V

excitation) or 2 V (12/24 V excitation) if it has been changed

for other input types.)

Detecting pulse edge: OFF (input monitor LED ON) to ON

(LED OFF)

■ Voltage Pulse

Waveform: Square or sine

Input impedance: 10 kΩ min.

Pulse amplitude: 0.1 – 100 Vp-p

Max. voltage between input terminals: 50 V

Detecting level: 0 – 5 V

(Detecting voltage in the internal circuit.)

Detecting pulse state: A pulse rise detected when the input

voltage goes above the detecting level (input monitor LED

ON); a pulse sink detected when it goes below

the level (LED OFF).

■ RS-422 Line Driver Pulse

Receiver: Conforms to RS-422
