Product Details
Input/Output cable for GL is required to connect the signal.
Input signal,
Voltage range: Up to 24V (common ground)
Signal type: Voltage, Open collector, Contact (relay)
Threshold: Approx. + 2.5 V (Hysteresis: Approx. 0.5V (2.5V to 3V))
Output signal: Open collector (pull-up to 5V by 10kΩ resistor)
Voltage: Max. 30V,
Current: Max. 0.5A,
Collector dissipation: Max. 0.2W
Minimum interval varies by number of channels used.
Output port can be specified in each input channel.
The built-in Flash memory is available for units with serial numbers C604XXXX or later.
SD memory card cannot be used on the SD card slot while the wireless LAN unit is used.
Size of the capture data will be limited to 1/3 of available memory.
Display mode is switched every time the dedicated key is pressed. In magnified digital value mode, the displayed channel number can be specified. In the waveform display mode, the changing of the time scale will be effective from the point of the next displayed data.
Rating under maximum power consumption using the AC adapter, with LCD display on, and battery pack(s) being charged.
Excludes AC adapter and battery pack.
