Emergency stop module with voltage failure detection
BH 5903

The BH 5903, BL 5903 of the SAFEMASTER series enables automatic restarting of systems after a power failure. It is specially designed for applications that require immediate restarting when power is restored. Examples include compressor controls and water and wastewater technology.

Advantages
. E-stop with latching function
. Automatic start when voltage returns after phase failure when no E-Stop was operated before phase failure
. Cross fault monitoring
. Short circuit and broken wire detection on all inputs
