The Honeywell FS-MB-0002 is a high-capacity mains power rail engineered for the distribution of DC voltage within Safety Manager systems. It is designed to facilitate reliable power delivery from redundant power supply sources to various controllers, I/O modules, and field devices in industrial automation and safety-critical environments.
Features
- Supports DC voltage distribution from 24Vdc to 110Vdc.
- High-capacity design supporting up to 200 Amps continuous current.
- Features 48 total connection points across four 6-inch sections.
- Flexible connector compatibility: Supports Jackscrew (JCK) connectors for high-current applications and Squeeze-To-Release (STR) connectors for standard wiring.
- Constructed with dual copper rails for optimal conductivity and reliability.
- Integrated over-current and short-circuit protection for downstream device safety.
Applications
- Safety Instrumented Systems (SIS) and Fire & Life Safety installations.
- Power distribution for PLC I/O modules, sensors, and actuators in process control.
- Critical power management in oil and gas, petrochemical, and power generation facilities.
- Distributed control systems requiring robust, redundant power backbones.

Installation Guidelines
-
Safety First: Ensure all upstream power sources are locked out and tagged out (LOTO) before performing any installation or wiring tasks.
-
Grounding: The rail housing must be securely bonded to the main enclosure structural earth ground prior to energizing the system.
-
Mounting: Can be installed using the M5 center rear mounting hole (152.4mm interval) or via 4.5mm diameter holes on the rail sides and end caps.
-
Wiring: Use appropriate heavy-gauge cabling to accommodate the 200A maximum load rating. Ensure all terminal connections are tightened to specification.
-
Environment: Ensure adequate clearance for heat dissipation, particularly when operating near maximum current capacities.
