MTL 8910-PS-DC DC power module
The 8910‑PS‑DC is a high‑reliability DC‑DC power supply module originally manufactured by MTL (now part of Eaton Corporation), designed exclusively for the MTL 8000 Series I/O and control systems. It converts a wide‑range DC input into a regulated 12 VDC output, providing stable, isolated power to I/O modules, controllers, and field devices in critical process environments. The module supports redundant operation (1:1 pairing) to ensure uninterrupted power supply and system availability.
Applications
- MTL 8000 System Power Backbone: Supplies regulated 12 VDC power to MTL 8000 series I/O modules and control units.
- Redundant Power Configuration: Enables 1:1 redundant setup for fault‑tolerant control systems; automatic failover upon one module failure.
- Field Device Powering: Powers remote sensors, transmitters, and actuators in process plants.
- Industrial Control Cabinets: Provides isolated, noise‑free power for PLCs, DCS nodes, and safety‑related equipment.
- Harsh Environment Operation: Designed for continuous use in high‑noise, wide‑temperature industrial settings.
