Safety Controllers

UE 440 and UE 470 safety controllers have more functions and flexibility than a safety relay, but without the complexity and cost of a safety PLC.

The UE 440 is a configurable safety controller for applications such as safeguarding multiple robot cells at the same time. The UE 470 is designed for press brake applications. They offer 15 single-channel inputs, and up to seven can be configured as two-channel inputs, and eight outputs, of which two are safe output pairs. The UE 440/470 are rated Category 4, according to EN 954-1, and SIL 3, according to IEC 61 508. The emergency stop function is rated stop Category 0 or 1, in accordance with EN 418.
