Product Details:

FOXBORO CM902WL is a rack-mounted power supply module for FOXBORO I/A Series DCS cabinet, a heavy-duty power supply unit built for process automation. This power module adopts conformal coated PCB assembly and reinforced metal shielding frame, protecting internal AC-DC conversion circuits from vibration, dust and electromagnetic interference inside industrial control cabinets. It can be plugged directly into the DCS rack backplane and matched with dedicated terminal base for fast installation and convenient maintenance. It supplies stable DC power to I/A Series FBM field modules and internal bus circuits.

This FOXBORO CM902WL DCS power module accepts wide 100~240VAC input, converts AC power into regulated 39VDC output with 1.7A continuous current. It provides stable power for analog input modules, discrete I/O modules and communication interface cards. The module integrates overvoltage, overcurrent, short-circuit and thermal protection. It cuts off output automatically when load fault occurs to prevent cascading damage to other DCS cards. Built-in continuous self-diagnosis function monitors input voltage, output voltage and internal temperature. It triggers alarm output once detecting power failure, overheat or load abnormality, helping maintenance engineers quickly locate power faults and reduce unplanned plant downtime. It supports hot swap operation, technicians can replace the module without shutting down the whole DCS system, which is critical for continuous production plants.
