SERIES SRB 202 MSLMuting Safety Controller(for dry contact & PNP-type input monitoring)TECHNICAL FEATURESDescriptionA muting safety controller permits the safety function to betemporarily disabled for reasons related to equipment ormachine work cycles. Disabling the safety function for a limitedperiod of time is referred to as “muting.” Muting is usedto permit the access of materials of production and preventaccess by personnel. A typical muting application is for palletentrance and/or exit from a hazardous area (palletizing).Activation and subsequent de-activation of the muting functionmust be achieved using two or more hard-wired andindependent signals (i.e., limit switches, optical or proximitysensors) activated by a proper time or space sequence.Input Voltage24V DC# Discrete Input Devices 2-4 (muting sensors)MonitoredCompatible Input Device N.C.
