Product Details:

FOXBORO CM700TW is rack-mounted FBM21 power supply module for FOXBORO I/A Series DCS system, a high-performance DCS power module built for process automation. This power module adopts conformal coated PCB assembly and reinforced metal shielding frame, protecting internal power conversion circuits from vibration, dust and electromagnetic interference inside industrial control cabinets. It can be directly plugged onto the DCS rack backplane and matched with supporting terminal base for convenient wiring and fast maintenance. It converts AC input power into stable 24VDC power supply for FBM I/O modules and internal control bus.

This FOXBORO CM700TW DCS power module accepts wide range AC input and provides regulated 24VDC output to feed analog and discrete I/O cards. Built-in overvoltage, overcurrent, short-circuit and thermal protection will cut off output automatically when load fault occurs, to prevent cascading damage to other DCS modules. The module continuously monitors input voltage, output voltage and internal temperature. It triggers alarm information 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.
