Our Muting Light Curtain Monitoring Relays allow the automatic temporary suspension of the safety function if certain conditions are met. In material handling applications, material is allowed to pass through the protective field without shutting down the machine. In addition to muting, these modules monitor up to three light curtains with presence sensing device initiation (PSDI).
