DSCA114 57510001-AA

Expansion of Multi Channel RS232/V24 Asynchronous Serial Communication
As a DCS main control external serial port gateway, it provides multiple independent RS232 interfaces to achieve data exchange between the controller and third-party devices: recorders, upper monitoring terminals, analyzers, etc PLC、 The upper control station is compatible with the standard V24 industrial serial port protocol.
MXB Backplane Bus Data Interaction
Real time bidirectional transmission of serial port messages between on-site serial port devices and DCS control logic data is achieved through the rack MXB backplane bus (paired with DSBB175/DSBBB110A backplane) and AC410/AC450 main control.
Serial port electrical isolation anti-interference
Each serial port is equipped with independent electrical isolation and EMC filtering to eliminate strong electromagnetic interference from industrial field ground loops and frequency converters, ensuring stable long-distance serial communication and avoiding signal garbled and disconnected signals.
Real time communication diagnosis and fault reporting
Continuously monitor serial port disconnections, communication timeouts, parity errors, and signal overloads; The panel LED status indicator light intuitively displays channel operation/faults, and the fault code is uploaded to the main control to quickly locate communication abnormalities.
Multi protocol adaptation forwarding
Support custom serial port parameters (baud rate, checksum, data bit, stop bit), adapt to various old-fashioned analyzers, recorders, and third-party instruments, complete data acquisition and command issuance.
Hot swappable online replacement
The replacement of the cabinet with live plugging and unplugging does not require shutdown, does not interrupt the entire cabinet control circuit, and does not affect the operation of other I/O and communication cards.
Full range Advant hardware compatibility
Perfectly matched with DSBB backplane, DSBC bus relay/expansion card, DSAO/DSAI/DSDI full range of analog and digital I/O modules, can be mixed and plugged into the same rack.
