Evaluation unit CES-A-ABA…/CES-A-UBA… (for 1 read head)

• 1 read head can be connected
• 2 safety contacts (relay contacts)
• 1 internal normally open contact per safety contact
• Unicode evaluation unit
• Category 3 / PL e according to EN ISO 13849-1

Unicode evaluation unit

Each actuator is highly coded (unicode). The evaluation unit detects only actuators that have been taught-in. Max. 8 actuators can be taught-in.

Only the last actuator taught-in is detected.

Category according to EN ISO 13849-1

Due to two redundant relay outputs (safety outputs) with internally monitored contacts, suitable for:

• Category 3 / PL e according to EN ISO 13849-1

To achieve the stated category, both safety contacts must always be evaluated.

Actuating range

The standard version of the evaluation unit (CES-A-…-01B) has a large actuating range that, e.g., permits larger tolerances in the alignment of read head and actuator. Wherever a smaller actuating range is required, the version with reduced actuating range (CES-A-…-01) can be used.
