Safety | Integrated safety technology with safety modules

The SCL284 module – ideally integrated in the M1 controller – is presented as an independent, safe, and modern safety controller. The safety processor module SLC284 is approved in accordance with the latest safety norm, IEC 61508.

No additional cabling is needed for communication between the SLC284 and the safety I/O modules SDI208 and SDO204. The modules can be separated by several hundred meters and operated in a distributed manner via the bus expansion or via FASTBUS, or via CAN or bluecom.

• 16 digital inputs / 8 digital outputs – can be used redundantly in pairs (PL e/SIL3/Cat 4)
• Each output with emergency delay is configurable in the event of communication lost
• Safety Controller with two independent 32-bit microcontrollers
• Fastest program cycle 5 ms
• Decentralized I/O via FASTBUS or bus expansion with SDI208 or SDO204
• All safety I/O states can be used by the M1 controller
• Safety programming via SolutionCenter
• Galvanic isolation between the groups
• Galvanic isolation from the system bus
• Operating mode selector switch
• Operating status display »SAFE«, »PROG«, »TEST«, »ERROR«
• Status display for each channel via LED
• Programming via independent serial interface or via controller

The SDI208 module adds an additional 8 input channels to the SLC284 safety processor module. A homogeneous total system is created through independent and safe integration in the M1 controller. Through the free choice of the slot – either directly beside the safety controller, through bus expansion, or several hundred meters away through the FASTBUS – the safety system can be optimally adapted to the distributed requirements and existing infrastructure of the system.

The SDI208 safety digital input module is approved under the latest safety standard IEC 61508. The SDI208 can be easily integrated in the safety application, comparable with a standard I/O module – as the proven »SolutionCenter« development platform offers the easiest configuration, most flexible type of programming, and a safe simulation via easily combinable PLC-Open function modules. All variables, and states of the SDI208 safety digital input module are accessible in all other machine program languages (PLC, C/C++); visualization is also available and makes cumbersome parallel wiring unnecessary.

• 16 digital inputs – can be used redundantly in pairs (PL e/SIL3/Cat 4)
• Safe monitoring of the inputs with redundant 32-bit microcontrollers
• Several SDI208 modules per controller possible
• All safety I/O states can be used by M1 controller
• Safety programming via SolutionCenter
• Galvanic isolation between the groups
• Galvanic isolation from the system
• Operating state display »SAFE«
• Status display for each channel via LED

The SDO204 module adds an additional 4 output channels to the SLC284 safety processor module and a homogeneous overall system is created through the independent and safe inclusion in the M1 controller. Through the free choice of the slot – either directly beside the safety controller, through bus expansion, or several hundred meters away through the FASTBUS – the safety system can be optimally adapted to the distributed requirements and existing infrastructure of the system.

The SDO204 safety digital output module is approved under the latest safety standard IEC61508. The SDO204 can be easily integrated in the overall safety application, comparable with a standard I/O module – as the proven »SolutionCenter« development platform offers the easiest configuration, most flexible type of programming, and a safe simulation via easily combinable PLC-Open function modules. All variables and states of the SDO204 safety digital output module are accessible in other machine program languages (PLC, C/C++), however the visualization is also available and makes bothersome parallel wiring unnecessary.

The SCT202 is a safety module for measuring safety-related rotations. For this it provides inputs and outputs which enable the implementation of safety applications up to SIL2 and PLd.

The module offers the following I/Os:

• Two safety input blocks that can be used as an incremental interface (each connectable with symmetrical A/B/N tracks). The measuring result is available to the user both as a frequency as well as in the form of a counter status.
• Two safety input blocks that can either be used as a counter input (connection of initiators) or latch or referencing inputs.
• Two safety digital inputs that can also be used as latch or referencing inputs.
• Two safety digital outputs as safety short response shutdown contacts which are ideal for overspeed detection (reaction time: ≤ 1 ms).

Other special features:

• Frequency measuring directly in the module
• Qualified for use as non-safety counter / speed measuring module
• Integrated referencing function (initiator, zero pulse and combination, as well as via software)
• High speed shutdown on overfrequency
• Zero speed monitoring
• Available as ColdClimate module
