Datalogging for High Voltage Monitoring

Multi-Input Unit

Withstand High Voltage Unit



Expandable up to 200 channels

Standad configuration has 20 analog input channels. lt is expandable to 200 channels by adding the optional 20 channel extension terminal base unit (B-566) and input terminal units (B-564 or B-565).

The following shows how a standad configuration is expanded to a 40 channel configuration.





Input Terminal Unit Types GL840-M I Multi-input (B-564) GL840-WV I Withstand-Voltage (B-565)

  • Wireless LAN capability | remote monitoring & datalogging
  • Flexible input system for wide array of applications | RTD' T/C
  • Ability to access additional (GL100) sensors & adapters
  • Extended memory capacity using SD memory card
  • Max sampling interval up to 10ms
  • Smartphone access




Accommodates a wide variety of measurements
Multifunction analog input ports
Contains a highly isolated input mechanism which ensures that signals are not corrupted by noise from other channels. The GL840 inputs are suitable for combined measurements from voltage, temperature, humidity, logic, and pulse
4 channels of Logic/Pulse inputs
Supports 4-channel logic or pulse signal inputs. Pulse mode allows cumulative, instant, or rotational values for industrial measurement capability with speed and flow.



Large easy-to-read 7-inch wide color LCD
Carries a clear 7-inch wide TFT color LCD screen (WGA: 800 x 480 dots)
for the GL840, and 4.3-inch wide LCD screen Monitoring data are
displayed in waveform or digital form option. Parameter settings can be
displayed on the screen.

Alarm function
Trigger action Start or stop capturing data by the trigger
Repeat action Off, On (auto rearmed)
Trigger source Start: Off, Measured signal, Alarm, External, Clock, Week or Time
Stop: Off, Measured signal, Alarm, External, Clock, Week or Time
Condition Setting Combination: OR or AND
Analog signal: Rising (High), Falling (Low), Window-in, Window-out
