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.

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
signals.
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.
