CES-AZ-UES-02B (Order no. 105140)

Evaluation unit CES-AZ-UES-02B (for 2 read heads)

2 read heads can be connected
2 safety outputs (relay contacts with 2 internally connected NO contacts per output)
Start button and feedback loop can be connected
Multicode
Plug-in connection terminals
Category 4 / PL e according to EN ISO 13849-1

Description

Multicode evaluation

Every suitable actuator is detected by the evaluation unit.

Guard lock monitoring

Evaluation units in the series CES-AZ make it possible to use read heads with integrated guard locking for the protection of personnel during overtraveling machine movements. You will find suitable read heads in the accessories.

Category according to EN ISO 13849-1

Due to two redundant safety paths (relay contacts) with 2 internal, monitored normally open contacts per safety path, suitable for:

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

Each safety path is independently safe.
