Extremely Compact and Cost-Efficient Safe Speed Monitors for Sensors/Initiators: Safety Basic Monitors
Autonomous compact safety controller 4 × 2-channel safe inputs or standard inputs and status outputs Speed monitor on the local inputs2 axes 2-channel (SIL2, PLd) or SIL3, PLe) 4 axes 1-channel (SIL1, PLc) Standstill monitor on the local inputs4 axes 2-channel (SIL2, PLd) 2 safe electronic outputs USB or Ethernet interface for configuration Detailed diagnostics and shut-off history via software or control Chip card for easy device exchange
And all in one unit with just 22.5 mm installation width
Speed monitoring with 2 sensors, monitor max. 2 axes
Speed monitoring with 1 sensor, monitor max. 4 axes
Speed monitoring in the Gateway
Safe speed monitors for encoders
Monitor up to 2 axes, up to SIL3, PLe For sine/cosine, SSI, TTL or HTL-Encoder Detailed diagnostics and shut-off history via software Chip card for easy device exchange 22.5 mm width Devices with local safe outputs
2 safe electronic outputs Support of all safety functions acc. EN 61800-5-2 Any number of safety functions can be implementedPossibility to configure several functions or same function with different parameters for each axis Max. 128 devices configurable
Encoder signal between encoder and converter is tapped.
Encoder is connected directly to the Speed Monitor.
What speed monitors are able to do
Safe monitoring of:
Standstill Speed Speed range Direction Shaft break Belt misalignment Slippage
Even for different gear trains
Break control Position End position Position range Safety Gateways with Safe Fieldbus Connection Safe speed monitoring in the drive
Motors with integrated Speed Monitor and safe fieldbus connection easily controlled using our Safety Gateway:
Of course Bihl+Wiedemann also offers Safety Gateways for combining with a Safe PLC (F-CPU):
Safety Gateway and frequency inverters with integrated Speed Monitor connected over a safe fieldbus.
Applications Safe speed and position monitoring with encoders
Storage and retrieval system
Simple and intuitive Configuration of I/O modules and speed monitors Online diagnostics Remote maintenance
Diagnostics over Fieldbus Safe speed monitoring in the gateway or module
12 terminals on the integrated Safety Monitor freely configurable, e.g.:6 safe outputs plus 3 safe 2-channel inputs 6 safe 2-channel inputs Standard I/Os Any combination thereof Speed monitor on the local inputs3 axes 2-channel (SIL2, PLd) 6 axes 1-channel (SIL1, PLc)
