Product Details：

Honeywell 51303932401 (51303932-401, MU-TSIM12) is a multi-channel serial device interface module for Honeywell Experion PKS C300 controller system. It belongs to the same TSDT communication family, designed to expand multi-port serial access capacity for PKS control cabinets, and it supports multiple independent serial channels to connect a large group of field serial instruments at the same time. This module supports RS232 and RS485 physical interfaces, compatible with standard serial protocols, and it can connect online analyzers, weighing controllers, auxiliary recorders, old serial regulators and other third-party serial slave devices. It converts serial data collected from field instruments into internal backplane bus data recognized by the C300 controller, so all process variables and equipment status data can be displayed, recorded and involved in interlock and calculation logic on the Experion operation station. Each serial channel can be configured separately for baud rate, data bit, parity check and stop bit parameters in Control Builder software, which brings great flexibility for mixed arrangement of different serial devices. It has built-in independent channel watchdog and frame error detection mechanism for every port, which can effectively reduce garbled data and packet loss caused by long-distance field cables and strong electromagnetic interference from frequency converters and high-power equipment in the cabinet. The module carries comprehensive self-diagnosis function, it can monitor channel disconnection, slave response timeout, checksum error and backplane communication failure separately for each channel, and send classified alarm information to the HMI station. Maintenance staff can quickly locate which serial channel or instrument has failed, and avoid the whole communication network being affected by a single faulty device. It supports hot swap operation under lockout-tagout maintenance procedures, technicians can replace the faulty module directly without cutting off the cabinet power supply, so the normal running control loops and other serial channels will not stop working. It adopts standard rack mounting structure for PKS series cabinet, and needs to work with the matched MU-TSIM12 serial FTA termination board to complete signal isolation, surge protection and field wiring terminal arrangement. It is widely used in petrochemical, chemical, power generation, pharmaceutical and water treatment automation projects, especially suitable for old DCS transformation projects with a large number of scattered serial instruments, and it helps reduce the total number of communication modules inside the control cabinet and save cabinet installation space. It is a reliable multi-port serial expansion hardware to enrich the heterogeneous equipment access capability of Experion PKS system.

Key specifications：Honeywell 51303932-401 serial interface module,backplane powered,multi-channel design,supports RS232 / RS485,per-channel configuration,communication self-diagnosis,rack mount. Operating temperature range: -10°C to +60°C. It supports single-channel communication test, serial parameter configuration and fault alarm verification during maintenance.

This MU-TSIM12 serial interface module cooperates with Honeywell C300 controller and matched serial FTA board to build stable multi-point serial communication architecture. LED status indicators for each channel help engineers check communication status and troubleshoot abnormal ports conveniently.
