Features:
- Four separately fused 24 VDC branches
- Individual fuse LEDs
- Collective fuse-status relay
F7133 organizes protected auxiliary power into four independently serviceable branches.
A local LED identifies the affected fuse, while the collective relay gives the cabinet a remote indication that the monitored set is no longer healthy.
Branch current, conductor size, fuse selectivity, relay-contact loading, and isolation practice are established from the downstream circuit design.
Apter Power supports quotation requests and official HIMA documentation access for the HIMA F7133 Four-Channel Power Distribution Module.

Four fused 24 VDC distribution channels
- Branch count: F7133 divides the incoming rack supply into four separately protected output channels.
- Fuse type: Each branch uses a 5 x 20 mm, 4 A time-lag G-fuse cartridge specified for the module.
- Negative distribution: The assembly includes L- distribution so the protected circuits can share the documented return arrangement.
- Load allocation: Connected devices are grouped so the expected current of one branch remains below its fuse and conductor limits.
- Selectivity: Branching the supply helps isolate a downstream fault without unnecessarily removing every auxiliary cabinet load.
Indication and alarm of fuse condition
- Channel indication: Individual status indicators identify which protected branch requires inspection.
- Collective alarm: A common monitoring contact lets the cabinet control design report loss of fuse health remotely.
- Delayed element: The time-lag characteristic tolerates permitted short inrush conditions while continuing to protect sustained overloads.
- Fault tracing: Technicians can compare the local indication, collective signal, and branch load before replacing a cartridge.
- Safety limitation: Fuse monitoring reports power-distribution health but does not itself prove that the connected final element can operate.
Connecting the power-distribution module
- Supply input: The documented 24 VDC feed is applied through the rack-side connection assigned to F7133.
- Protected outputs: Four front-side branches route the fused positive supply to the selected field or interface loads.
- Return path: L- terminals preserve the negative distribution scheme used by the associated HIQuad cabinet.
- Conductor sizing: Wire cross-section, terminal rating, branch current, and upstream protection are coordinated before energization.
- Safe service: External isolation and verification of a de-energized state are required before fuse or terminal work.
Cabinet circuits supplied through F7133
- Safety modules: Protected branches can feed approved HIQuad modules that require separately fused 24 VDC distribution.
- Field interfaces: Interface assemblies and signal-conditioning circuits use the module where a monitored cabinet supply branch is specified.
- Alarm circuits: Annunciators and auxiliary alarm devices can be grouped on a branch sized for their steady and inrush current.
- Final-element auxiliaries: Valve, relay, or contactor interface circuits can receive protected power when their load remains within the documented branch design.
