Expansion of a WB component to include up to four digital inputs

Category: Tags: ,

Description

The WB-DI 4 component is equipped with potential-free inputs. It has no built-in intelligence. Its typical area of application is the flexible configuration of a system, for example where different control variants are required within a single system. In such cases, this component can accommodate a wide variety of combinations simply by reprogramming the main unit when servicing is required. Thanks to the voltage withstand capacity of the digital inputs, the module can also cope with the occasional high voltage spike.

The WB-DI 4 has one particular feature: it is capable of self-monitoring.
