HIOKI 9320-01 Logic Probe

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: 1.4 V/ 2.5 V/ 4.0 V

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)

Detectable pulse width: 500 ns or longer

Max. allowable input: 0 to +50V DC (the maximum voltage that can be applied across input pins without damage)
