Product Details：

Honeywell 51303932226 (51303932-226, MU-TSDT02) is the serial device interface module for Honeywell Experion PKS C300 controller system. It serves as the communication gateway between the PKS control backplane and external serial field instruments, supporting RS232 and RS485 serial communication protocols to connect third-party devices such as weighing instruments, analyzers, barcode readers and old serial-type regulators that cannot be directly accessed via UCN bus. The module converts serial protocol data into internal bus data recognized by the C300 controller, so process data from these peripheral devices can be displayed, recorded and involved in interlock or calculation logic on the Experion operation station. It supports multiple common serial communication modes, with built-in data parity check and frame error detection mechanism to reduce data packet loss and garbled code caused by long transmission cables and on-site electromagnetic interference. It has complete self-diagnosis function, which can monitor serial port disconnection, communication timeout, data check error and backplane link abnormality, and send alarm messages to the HMI station for maintenance personnel to quickly locate communication faults. It supports hot swap under lockout-tagout maintenance procedures, technicians can replace the module without powering off the whole cabinet, avoiding shutdown risk of other normal control loops. It adopts standard rack mounting structure for PKS series cabinet and works with serial FTA termination board to complete signal isolation and terminal wiring. It is widely used in petrochemical, chemical, power and water treatment automation projects, used for connecting legacy serial instruments, on-line analyzers and auxiliary equipment, solving the problem of heterogeneous equipment access in the transformation of old DCS systems. It is an indispensable communication accessory to expand the access capability of Experion PKS system.

Key specifications：Honeywell 51303932-226 serial interface module,backplane powered,supports RS232 / RS485,data parity check,communication self-diagnosis,rack mount. Operating temperature range: -10°C to +60°C. It supports serial communication test,protocol matching and fault alarm verification during maintenance.

This serial interface module cooperates with Honeywell C300 controller and serial FTA board to build stable heterogeneous device communication architecture. LED status indicators help engineers check link status and troubleshoot communication problems conveniently.
