Hioki Logic Probe 9320-01, 9320

Detect the presence of voltage or relay contact signals with Memory HiCorders

The 9320-01 and 9320 are 4-channel logic probe used to detect voltage or relay contact signals with Hioki Memory HiCorders.

Connects to the logic input terminals of Hioki Memory HiCorders. Check the size of the terminal before purchase.

Detect Hi/Lo voltage or relay contact signals
• 4 channels with common ground
• Switch between digital or contact input
• 3 thresholds for digital input (+1.4/+2.5/+4.0V)
• Supports pulse widths as narrow as 500ns
• 9320-01 features a miniature connector, and 9320 features a larger connector for legacy products

Basic specifications (Accuracy guaranteed for 1 year)

Note: The unit-side plug of the 9320-01 is different from the 9320

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)
Response pulse width 500 ns or more
Max. allowable input 0 to +50V DC (the maximum voltage that can be applied across input pins without damage)
