Description
Logic Probe 9327 for Voltage and Relay Signal Analysis
The Logic Probe 9327 is a compact and high performance input module designed to capture fast changing voltage and relay contact signals using Hioki Memory HiCorders. It is built for engineers and technicians who need precise High and Low state detection in control circuits, automation systems, and electronic testing environments.
With support for both digital input and contact input, the Logic Probe 9327 adapts easily to different signal types. Users can monitor standard voltage signals or detect relay contact states, including open collector signals, without modifying the test setup. This flexibility makes the probe suitable for evaluating control boards, logic circuits, and relay driven systems.
One of the key advantages of the Logic Probe 9327 is its high speed response capability. It can detect pulse widths as short as 100 nanoseconds, allowing accurate capture of fast transient events that slower probes may miss. This makes it especially useful for timing analysis, signal validation, and debugging high speed digital circuits.
The probe features four input channels with a common ground, enabling efficient multi signal monitoring while maintaining a compact form factor. Three selectable digital input thresholds allow users to match detection levels to the logic standards used in their system. This improves signal reliability and reduces the risk of false triggering.
Designed for ease of use, the Logic Probe 9327 connects directly to the logic input terminals of compatible Hioki Memory HiCorders using a miniature connector. Its lightweight housing and included clip accessories make it easy to deploy in both laboratory and field environments.
Whether you are diagnosing relay behavior, verifying control logic, or capturing high speed pulses, the Logic Probe 9327 delivers dependable performance, fast detection, and seamless integration with Hioki measurement systems.
