Basic specifications
Note: The unit-side plug is miniature terminal type

Function Detection of voltage signal or relay contact signal for High/Low state recording
Input 4 channels (common ground between unit and channels), digital/contact input, switchable (contact input can detect open-collector signals)
Input resistance: 1 MΩ (with digital input, 0 to +5 V)
500 kΩ or more (with digital input, +5 to +50V)
Pull-up resistance: 2 kΩ (contact input: internally pulled up to +5 V)
Digital input threshold 1.4V/ 2.5V/ 4.0V
Contact input detection resistance 1.4 V: 1.5 kΩ or higher (open) and 500 Ω or lower (short)
2.5 V: 3.5 kΩ or higher (open) and 1.5 kΩ or lower (short)
4.0 V: 25 kΩ or higher (open) and 8 kΩ or lower (short)
