CES-A-ABA-01 (Order no. 071850)

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

Description

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 evaluation unit has a reduced actuating range.

TST

Input for self-test

OUT

Monitoring output (semiconductor)

ERR

Diagnostic output
