3. Key Features
Redundant Fault‑Tolerant Operation: Supports single‑module independent operation or dual‑module redundant backup. Automatic primary/backup switching ensures zero system downtime and no protection trip caused by single power supply failure.
Non‑Stop Hot‑Swap Maintenance: Ideal for continuous‑process industries including power generation, petrochemical, and oil & gas. Technicians can replace faulty modules online without unit shutdown or system power‑off.
Built‑In Electrical Protection: Integrated over‑voltage, over‑current, and under‑voltage protection circuits. Under‑voltage conditions will not damage the module, providing strong tolerance to unstable field power.
Visual Status Indication: Equipped with a front‑panel SUPPLY OK LED for real‑time operational status monitoring, enabling fast on‑site inspection and fault diagnosis.
4. Compatibility & Critical Restrictions
The 114M5330‑01 low‑voltage DC power supply must be used with a dedicated low‑voltage DC PIM module. Do not mix with high‑voltage DC PIM, AC PIM, or legacy PIM versions. Mismatched PIM hardware causes power failure, system alarms, and permanent hardware damage.
5. Application Scenarios
Widely deployed in TSI protection systems for rotating equipment including steam turbines, centrifugal compressors, industrial blowers, and large pump units. Common industries: thermal power, petroleum, chemical processing, and oil & gas storage. This module is the preferred power solution for field cabinets with only 24VDC power availability.
6. Matching & Compatible Part Numbers
Mandatory Matching Part (Only Compatible Partner)
114M5330‑01 power supply requires 114M5335‑01 (Low Voltage DC PIM Module)

8. 3500/15 Ordering Code Rule
Format: 3500/15‑AXX‑BXX‑CXX
Definition:
AXX = Upper slot power configuration
BXX = Lower slot power configuration
CXX = Explosion‑proof certification
Code Index: 01=Low AC, 02=High AC, 03=High DC, 04=Low DC, 05=Universal AC, 00=No power
Example: 3500/15‑04‑04‑00 = Dual low‑voltage DC power (2 × 114M5330‑01), no explosion‑proof certification
9. Selection Guidelines & Installation Notes
1. No PIM Mixing Allowed: AC power matches AC PIM; DC power matches DC PIM. New and legacy PIM hardware and firmware are incompatible.
2. Flexible Redundancy: Supports AC+DC hybrid redundant configuration for dual‑source backup protection.
3. Unified Industrial Grade: All new‑generation modules feature 0~55℃ operating temperature and full hot‑swap capability.
4. New Projects Use New Parts Only: Legacy models are phased out by the factory and only available for legacy equipment spare replacement.
10. Troubleshooting Guide
1. SUPPLY OK LED Off
Check external 24VDC input voltage stability; inspect DC PIM wiring, terminal looseness, and cable connection integrity; verify power and PIM part number matching.
2. Single Power Alarm in Dual Redundant System
Confirm primary/backup slot installation position; strictly verify PIM and power module compatibility.
3. Intermittent Recurring Alarms
Inspect field 24VDC power capacity. Full 3500 rack loading requires sufficient upstream power budget; insufficient capacity causes frequent power module alarms.
