SDO204

The SDO204 module adds an additional 4 output channels to the SLC284 safety processor module. A homogeneous total system is created through independent and safe integration in the M200 controller. Through the free choice of the slot – either directly beside the safety processor module, 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 input module is approved under the latest safety standard IEC 61508. The module 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 PLCopen function blocks. All variables, and states of the SDO204 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. The output current of 2 A per channel allows direct control of hydraulic valves.

• 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
• Safe monitoring of the outputs with redundant 32 bit microcontrollers
• Several SDO204 modules per controller possible
• All safety I/O states can be used by M200 controller
• Safety programming via SolutionCenter
• Galvanic isolation between the groups
• Galvanic isolation from the system
• Operating status indication "SAFE"
• Status indication for each channel via LED
