DSBC172 57310001-KD

MXB/S100 bus signal regeneration relay
Shaping, amplifying, and synchronously regenerating bus signals inside and outside the rack to extend the bus communication distance; Solve the problems of signal attenuation and distortion in long cables, and support multi rack distributed I/O networking.
Real time monitoring and diagnosis of the entire system bus
Continuously inspect the timing, communication integrity, and bus load of the backplane bus; Real time monitoring of short circuits, wire breaks, and signal distortions, intuitive warning of panel LED fault indicator lights, uploading fault codes to the main control AC410/AC450, and quickly locating communication abnormalities.
Dual bus isolation anti-interference
Built in electrical isolation and EMC filtering circuit, suppresses EMI RF interference from frequency converters and high-voltage equipment, eliminates ground loops, ensures the accuracy of analog AO/AI signals, and adapts to strong interference conditions in power plants and chemical industries.
Redundant bus automatic switching
Supports A/B dual redundant bus links, automatically switches without disturbance in the event of a single bus failure, and does not interrupt the production control loop throughout the entire process, meeting the requirements of high reliability continuous processes.
Rack bus timing synchronization coordination
Unified communication clock synchronization among multiple racks ensures consistent data scanning cycles across multiple I/O racks and avoids control logic timing confusion.
Plug and play hot swappable
The cabinet can be plugged and replaced separately when it is live, without the need for shutdown or program modification, and does not affect the operation of the entire DCS system.
Compatible with all series of cards
Perfectly matched with DSBB110A, DSBB175 backplane, DSAO120A analog output card, and DSAI/DSDI full series Advant I/O modules.
