Generic safety controller board enables bespoke solutions
The board is pre-certified and enables users and system integrators to reduce time-to-market of customer-specific safety controllers in networked applications with high availability. It suits for use in stand-alone applications as well as in networked control systems. A safety controller consists of the generic safety controller board and a customer-specific I/O board.
The safety controller board is equipped with RS232, SPI, CAN und two-channel TTEthernet communications interfaces. It is powered by a dual-core lockstep TMS570 (code name Hercules) controller from Texas Instruments, for fail-safe code execution, combined with a Safety Companion Chip to monitor the supply voltage. The interfaces include GPIO, analog inputs, PWM outputs and advanced I/O functions based on a NHET unit. All interfaces dispose of diagnosis functions according to IEC 61508 SIL2.
The board comes with certifiable firmware, runtime system and drivers for I/O and network interfaces. A safety manual as well as IEC 61508 certification artefacts and related safety standards are available.
