Response time of the
complete system Response time 3SF7842 + response time of AS-Interface safety monitor (max. 40 ms)
Degree of protection IP65
Supply current in mA Max. 130 (transmitter)
Max 140 (receiver)
Operating mode Protection mode without restart lockout
Transmitter/receiver synchronization Optical synchronization, two transmission channels can be selected
Infra-red disturbance suppression Two techniques for selection:
Standard = high suppression
d-scan = extremely high degree of suppression
