CES-CB Configurable Evaluation Unit


Euchner CES-CB combines all the advantages of existing evaluation units with the option of connecting up to 4 CES Unicode and Multicode read heads in a single unit using a choice of 25 pre-programmed configurations. Integrated logic functions combined with 3 independent safety outputs and 6 monitoring outputs provide for flexability. Two CES-CB units can be combined to create safety zones. Configurations can be selected via a rotary pushbutton and menu display. *See Switch Compatibility below.

Note: The connection set needed for this Evaluation Unit (sold separately) is part number 104776.
