Input terminal blocks can be connected directly(in daisy chain), or using the B-565 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.
