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

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 enables a reduced actuating range.

TST

Input for self-test

OUT

Monitoring output (semiconductor)

ERR

Diagnostic output

GND

Connected internally to 0V (not for high currents)
