UPS Control Modules
APC Symmetra™ and PX-series UPS systems, and other brands of UPS, rely on intelligent control modules to manage system logic, redundancy, communication, and overall operational stability. These Main Intelligence Modules (MIM) and Redundant Intelligence Modules (RIM) serve as the command center of the UPS—coordinating power modules, monitoring system health, and ensuring seamless load protection.

Some are designed for specific Symmetra Power Array, RM, LX, and PX platforms, these modules provide critical system control, fault management, and redundancy capability. In N+1 configurations, paired main and redundant modules enhance uptime by maintaining continuous communication and automatic failover protection.
Whether you are replacing a failed unit, upgrading a legacy 1:1 system, or maintaining a 3:1 scalable configuration, control modules restore system intelligence, stability, and reliability—keeping your UPS operating exactly as engineered.
| APC Part | Module Type | Compatible UPS Family / Models | Notes |
|---|---|---|---|
| SYMIM | Main Intelligence Module | Symmetra Power Array 1:1 (legacy only) | Not compatible with 3:1 systems; replaced by SYMIM2. |
| SYRIM | Redundant Intelligence Module | Symmetra Power Array 1:1 (legacy only) | Not compatible with 3:1 systems; replaced by SYRIM2. |
| SYMIM2 | Main Intelligence Module (MIM) | Symmetra Power Array 4–16 kVA (1:1 & 3:1) | Use with classic Symmetra “tower” systems. |
| SYRIM2 | Redundant Intelligence Module (RIM) | Symmetra Power Array 4–16 kVA (1:1 & 3:1) | Pairs with SYMIM2 for redundancy. |
| SYMIM3 | Main Intelligence Module (MIM) | Symmetra RM 2–6 kVA and 8–12 kVA | Rack-mount Symmetra RM family. |
| SYRIM3 | Redundant Intelligence Module (RIM) | Symmetra RM 2–6 kVA and 8–12 kVA | Pairs with SYMIM3 for redundancy. |
| SYMIM5 | Intelligence Module (used as MIM or RIM) | Symmetra LX (e.g., SYA8K16P / SYA8K16RMP series) | Same part used for both main and redundant slots; install two for N+1. |
| SYMIM4 | Intelligence Module (3-phase PX) | Symmetra PX 3-phase UPS (e.g., SY40K40F / SYCF40KF | Used for main and redundant intelligence in PX frames. |
