51304648-225, also named MU-TDOA53, is a 16-channel AC solid-state relay digital output field terminal assembly. It is designed for Honeywell TPS, TDC3000 and Experion PKS DCS systems. This module works with MU-PDOX01 and MU-PDOX02 I/O processing cards to control 120/240 VAC field loads.

The prefix 5130 stands for Honeywell TPS, TDC3000 and Experion PKS distributed control system series. The code 4648 represents the category of AC digital output field terminal assembly. The suffix 225 refers to hardware revision R225, which is CE-certified, equipped with screw terminals and without conformal coating.

This module has 16 digital output channels adopting solid-state relay design. The rated load voltage is 120 VAC and 240 VAC, with a maximum load current of 2.5 amperes per channel. It provides channel-to-ground isolation, while there is no isolation between channels. Each channel is fitted with a 2.5 ampere fuse for overcurrent protection. The module is powered by 24 VDC from the backplane, with a voltage tolerance of plus or minus ten percent. All field connection terminals are screw type. This model has no conformal coating and holds CE certification. It does not support redundant configuration, and the hot swap function is available.

The module connects to the UCN I/O bus via backplane and is compatible with MU-PDOX01 and MU-PDOX02 IOP cards. Each channel is equipped with independent screw terminals for field wiring. It only supports board-level fault detection and cannot diagnose faults of individual channels. The hot swap feature allows module replacement without system shutdown.

It converts internal control signals into AC output to drive various AC electrical devices on site. The solid-state relay ensures fast response speed and long service life without mechanical wear. Built-in fuses offer reliable overcurrent protection for each output channel. Screw terminals enable convenient wiring and routine maintenance.

This product is compatible with Honeywell TPS, TDC3000 and Experion PKS systems. It is widely applied in petrochemical, power generation, water treatment and general manufacturing industries. It is mainly used for controlling 120/240 VAC loads such as AC solenoid valves, motor starters, electric heaters and alarm indicators.

Insert the module into the standard slot of the DCS cabinet and ensure firm connection with the backplane. Connect field AC equipment to the corresponding screw terminals correctly. Complete parameter configuration in the system software before putting the module into operation.

Keep the cabinet interior clean and dry. Inspect wiring terminals regularly to check for looseness and oxidation. Monitor the operating status of the module through system diagnostic tools. Store spare modules in anti-static bags and place them in cool and dry environments. Do not disassemble the module without permission. All maintenance work must be carried out by professional technicians.
