Features:
- •Single-slot redundancy module for standard ControlLogix chassis
- •Supports ControlLogix 5570 and 5580 controller families
- •Uses 1756-RMC1, 1756-RMC3, or 1756-RMC10 redundancy cables
1756-RM2 provides the hardware link used between qualified standard-chassis ControlLogix redundancy partners.
Procurement should align the module series, controller family, chassis, power architecture, and fiber-cable length on both sides.
A controlled replacement plan should preserve firmware records, project backups, diagnostic history, and the approved synchronization procedure.
Availability is subject to Apter Power's current inventory and sourcing confirmation.

Redundant controller pair planning
- •Controller match: Confirm the installed ControlLogix 5570 or 5580 controller family.
- •Chassis match: Use a supported standard 1756 chassis on both sides of the pair.
- •Power review: Document standard or redundant power architecture before replacement.
- •Series record: Capture the existing module series and firmware qualification record.
Redundancy-link preparation
- •Cable length: Select the documented 1 m, 3 m, or 10 m 1756-RMC cable.
- •Route control: Protect the redundancy cable from tight bends and unplanned rerouting.
- •Pair check: Verify both modules and the selected cable before synchronization.
- •Spare plan: Keep the cable identity with the module spare record.
Commissioning review
- •Configuration backup: Preserve the controller project and redundancy configuration.
- •Module identity: Check catalog number and series before installation.
- •Diagnostic review: Clear link and synchronization faults before acceptance.
- •Recovery test: Use the site procedure to confirm expected switchover behavior.
