CES-A-AEA-04B (Order no. 072000)

Description

Unicode evaluation unit

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

Only the last actuator taught-in is detected. New actuators are taught-in by fitting a jumper.

Category according to EN ISO 13849-1

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

  • Category 4 / PL e according to EN ISO 13849-1

Actuating range

The evaluation unit has the standard actuating range that, e.g., permits larger tolerances in the alignment of read head and actuator.
