SAIA PCD2.C100 – Expansion Supply Module | PCD2 Series Platform
Engineering Background
The SAIA PCD2 series is a modular, rack-based programmable controller platform widely deployed in building automation, industrial process control, and infrastructure management. As PCD2 systems scale in I/O density, the internal CPU power budget becomes a limiting factor. The PCD2.C100 Expansion Supply Module was engineered specifically to address this constraint, providing a dedicated, isolated power rail that feeds expansion I/O modules independently of the CPU card—enabling larger, more complex configurations without compromising system stability.
Product Positioning
The PCD2.C100 is the authoritative solution for engineers who need to extend a PCD2 rack beyond the base CPU power envelope. It is not a generic PSU—it is a purpose-built expansion supply designed to integrate seamlessly into the PCD2 backplane architecture, ensuring deterministic power delivery to I/O modules under full industrial load conditions.

Proven Application Environments
- Building Automation Systems (BAS): HVAC control panels requiring high I/O counts across multiple PCD2 expansion racks
- Industrial Process Control: Continuous manufacturing lines where I/O module count exceeds base CPU power budget
- Infrastructure & Utilities: Water treatment, energy management, and substation automation with dense sensor/actuator wiring
- Machine OEM Integration: Custom machine builders standardizing on the PCD2 platform who need scalable power architecture
- Retrofit & Upgrade Projects: Expanding legacy PCD2 installations without replacing the existing CPU or rack infrastructure
Engineering Advantages
- Dedicated Power Rail: Isolates I/O module power from the CPU, eliminating cross-interference and voltage sag under high-load conditions
- Backplane-Native Integration: Plugs directly into the PCD2 rack slot—no external wiring, no additional DIN rail PSU required
- Deterministic Power Delivery: Ensures stable voltage to all downstream I/O modules regardless of dynamic load changes
- Scalable Architecture: Allows engineers to maximize I/O density within a single PCD2 rack without hardware redesign
- Compact Form Factor: Occupies a standard PCD2 module slot, preserving rack real estate for additional I/O cards
- Long-Term Availability: Konmask maintains verified stock for MRO and project procurement needs
System Architecture & Signal Flow
In a standard PCD2 configuration, the CPU module (e.g., PCD2.M480) supplies power to the backplane for both logic and I/O modules. When the total I/O module count approaches the CPU’s rated output current, inserting the PCD2.C100 into a designated expansion supply slot offloads the I/O power demand onto a separate regulated rail. The CPU continues to handle logic power, while the C100 exclusively drives the I/O module bus—resulting in a clean, partitioned power architecture that supports maximum rack population.
Recommended slot placement and rack population rules are defined in the SAIA PCD2 Hardware Manual (document reference: 26/789). Konmask technical support can assist with rack power budget calculations prior to order.
Sourcing & Quality Verification
- All PCD2.C100 units sourced through authorized distribution channels or directly from SAIA-certified inventory
- Each unit undergoes incoming inspection: visual check, label verification, and functional power-on test where applicable
- Serialization and date codes verified against manufacturer records to confirm authenticity
- Counterfeit-risk mitigation: Konmask does not source from unverified grey-market channels
- Certificate of conformance (CoC) and test reports available upon request for project documentation
Procurement Process

Technical FAQ
Q: Can the PCD2.C100 be used in any PCD2 rack slot?
A: No. The C100 must be installed in a designated expansion supply slot as specified in the PCD2 rack hardware manual. Incorrect slot placement may result in backplane conflicts.
Q: Does the PCD2.C100 replace the CPU power supply?
A: No. It supplements it. The CPU module retains its own power supply for logic operations; the C100 exclusively powers the I/O module bus.
Q: Is the PCD2.C100 compatible with PCD1 or PCD3 racks?
A: No. The C100 is designed exclusively for the PCD2 rack backplane architecture and is not interchangeable with other PCD series racks.
Q: What is the lead time for in-stock units?
A: In-stock units typically ship within 1–3 business days. Contact Konmask to confirm current stock status before placing an order.
Q: Can Konmask provide a rack power budget calculation?
A: Yes. Share your rack model, CPU type, and I/O module list with our technical team and we will provide a power budget analysis at no charge.
