Input system 1 : Multifunction analog input ports

Contains a highly isolated input system which ensures that signals are not corrupted by noise from other channels.

The GL840’s inputs are suitable for combined measurements from voltage, temperature, humidity, logic, and pulse signals.

The standard configuration has 20 analog input channels.

It is expandable to 200 channels by adding optional 20 channels extension terminal base unit (B-566) and input terminal units (B-564 or B-565).

The following shows how a standard configuration is expanded to more than 40 channels ( Max.200 channels)

Offers longer cable for the input terminals

Input terminal blocks can be connected directly (in daisy chain), or using the B-567 cable(s).

This allows the input terminals to be placed in separate locations according to the need of the application.

The input terminal unit and the GL840 main body can be extended by using an extended connections cable.

* If the signal is affected by noise, it may be required to use a slower sampling.
