Series Information
Part of the PACSystems™ RX3i modular control platform. The “D” suffix denotes 24V DC input specialization for battery-backed or DC-distributed systems. Compatible with all RX3i CPUs (e.g., IC698CPE010) and I/O modules.
Key Features
- 24V DC Optimization: Designed for industrial DC power grids and UPS-backed systems.
- Reverse Polarity Protection: Safeguards against wiring errors.
- Redundancy-Ready: ≤1ms switchover with IC698PSD100D backup module.
- Wide Temp. Range: Operates in extreme conditions (-40°C to 70°C).
- Hot-Swappable: Field-replaceable without system shutdown.
- High Efficiency: >88% conversion minimizes heat buildup.
- Universal Backplane: Compatible with all RX3i chassis (5-15 slots).
Role & Purpose
- DC Power Conversion: Converts 24V DC input to backplane +5V DC.
- System Stabilizer: Provides clean power for CPU and I/O modules.
- Redundancy Enabler: Critical for fail-safe operation in power-sensitive applications.
- Electrical Protection: Filters noise and suppresses surges in DC networks.

Technical Notes
- 🔋 Battery Compatibility: Ideal for 24V battery/UPS-backed installations.
- ⚡ Redundancy Wiring: Requires IC698CBLxxx cables for parallel operation.
- 📉 Derating Curve: Output reduces to 75W at 60°C ambient.
- 🔌 Terminal Type: Screw-clamp connectors for 8-14 AWG wires.
- ️ Voltage Note: “D” variant not interchangeable with AC-input models (e.g., IC698PSA100).
Design Advisory:
For new installations, consider the higher-capacity IC698PSD350D (350W). Maintain IC698PSA100D for legacy DC systems via Emerson’s lifecycle support. Always pair with matched redundancy module (IC698PSD100D) for critical processes.
