Dec. 5, 2014 – Wieland Electric has developed a compact DIN rail mounted universal safety relay for monitoring a range of machine safety functions, including emergency stops, elevator access control, and heating/burner installations.

The SNO4083 series promises reliable monitoring for emergency stop and non-contact protection systems for machine operators in harsh industrial environments. Accepting inputs from single and dual channel emergency stop sensors with dry contacts (NO+NO or NO+NC) and PNP outputs from active sensors, it is available in 24 VDC or 115/230 VAC versions with either screw-clamp or spring-clamp pluggable terminations. The relay’s output features 3 NO and 1 NC auxiliary contacts. Synchronous time monitoring function (1.5s and 0.5s) ensures that faulty sensors or improper adjustment is detected, adds the company.
