Pilz PSS SB 3006 CN-A Compact Safety System

The Pilz PSS SB 3006 CN-A Compact Safety System with SafetyBUS p Connection Module is a compact safety system within a single housing. It can be connected to Control Net as an Adapter Class Product. The connection to the decentralized periphery devices is made via SafetyBUS p. An additional feature to the decentralized I/Os is the ability to connect a safety-related network of several PSS systems via SafetyBUS p. The integral on-board inputs can be used for local E-STOP monitoring or for triggering a group start. They are suitable or connecting single or dual-channel safety-related input devices, with or without test pulses.

The dedicated test pulses are designed for testing input devices with a load of 0.5A.

Safety systems in the PSS-range are divided into a failsafe section and a standard section. Safety-related functions can only be processed through the failsafe section. The failsafe and standard sections communicate without feedback, i.e. potential program errors in the standard section will not affect the failsafe section. The failsafe section of the CPU operates through three diverse channels, ensuring a high level of safety. All inputs are processed separately by each channel. Each channel compares the result with the two adjacent channels. Input signals are only valid if all three channels reach the same result.

Communication with supervisory systems, e.g. for diagnostic functions or for visualisation, is via the ControlNet Interface; if necessary this can be done via the user interface

An RS232/RS485 interface is available for connecting to the programming device.
