GS8511-EX. B explosion-proof elevator, safety door isolation safety barrier

GS8511-EX. B explosion-proof elevator, safety door isolation safety barrier, receives safety switch or contact switch inputs from hazardous areas, and transmits them to the safety area output through safety barrier isolation. The input signal processing adopts dual redundant circuits; The shutdown function is determined through mutual fault monitoring between channels and contact bonding. Specially suitable for monitoring and processing safety switch signals of explosion-proof equipment such as elevators and safety doors.
