DESCRIPTION

 

Developed to meet the requirements of signal conditioning rationally, the BCI 184 terminal block provides a solution for HIGH and LOW level analog input acquisition.

The high common mode of the BCI 184 enables ground and common mode problems to be overcome.

The BCI 184 terminals blocks also provides cold weld compensation for thermocouples, and platinum sensor conditioning and linearization.

Of painstaking design, it is used to advantage in industrial environments where the cost of conditioning has to be taken into account.
