Detect the Presence of Voltage or Relay Contact Signals with Memory HiCorders at High Speeds. The Logic Probe 9327 is designed to detect high/low voltage levels or relay contact states, and provide logic state monitoring when connected to compatible Hioki Memory HiCorder recorders (e.g., models 8855, 8860/61, MR8847 series). It enables precise digital signal capture and relay operation analysis in test, measurement, and industrial environments.
Key Features
- 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 V/+2.5 V/+4.0 V)
- Supports pulse widths as narrow as 100 ns using high speed response
- Miniature connector
Basic specifications
Note: The unit-side plug is miniature terminal type
| Function |

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 |
