CES-I-AP-U-C04-USI-EX-174983 (Order no. 174983)

Description

Version ATEX

Suitable for use in zones 2 and 22 (gases and dusts).
Application area II 3G D.

Housing guard

The Housing guard included in the scope of delivery protects the safety switch against impacts on the housing and the plug connector(s). The Housing guard must be fitted in order to achieve the specified explosion protection.

Approach direction and installation position

Permissible installation position

Unicode evaluation

Each actuator is highly coded (unicode). The switch detects only taught-in actuators. Additional actuators can be taught-in.

Only the last actuator taught-in is detected.

Safety characteristics

Thanks to two redundant safety outputs (semiconductor outputs) with internal monitoring, the device is suitable for:

  • Category 4 /PL e according to EN 13849-1
  • SIL 3 according to EN IEC 62061 Table 4

The OSSD outputs used check their function for short circuits and short circuits with test pulses.
