Technical data

Type Speed Monitor Modular
Safe Monitoring speed + position
Encoder signal/Sensor signal sine/cosine, TTL, SSI
Number of monitored axes up to 2 independent axes
Inputs Safety

Safe inputs can be configured as 1-channel or 2-channels depending on the desired application or PL and SIL level.

Suitable for applications up to category 4/PLe/SIL 3.

no local safe inputs
Outputs Safety

Suitable for applications up to category 4/PLe/SIL 3.

2 release circuits, 2 x electronic safe outputs
Encoder/Sensor connection RJ45
Diagnostic and configuration interface

Access to ASi master and safety monitor via own software from Bihl+Wiedemann using the diagnostic interface (e.g. USB, RJ45, RS232). For certain devices with Ethernet-based fieldbus (PROFINET, EtherNet/IP), there is also the option of diagnostics and configuration directly via the fieldbus interface.


The latest version of the device description file of the gateway/gateway with integrated safety monitor (GSD, GSDML, EDS, etc.) is available in the "Downloads" section of the respective device.
