| PCD2.A465 | Saia-Burgess | 16 | Transistor PNP | PCD2 platform; not plug-compatible |
| SM322 DO16×DC24V/0.5A | Siemens S7-300 | 16 | Transistor PNP | Cross-brand; requires rewiring & reprogramming |
| QY10 | Mitsubishi MELSEC-Q | 16 | Transistor (sink) | Cross-brand; NPN type, polarity differs |
| 1756-OB16D | Allen-Bradley ControlLogix | 16 | Transistor PNP | Cross-brand; different platform entirely |
Always verify electrical ratings, bus compatibility, and firmware requirements before substitution.
Why Choose the Original Model
- Native PCD3 bus integration — zero configuration overhead, plug-and-play on PCD3 racks
- Saia SG5 / FUPLA programming compatibility — no I/O mapping rework required
- Electronic short-circuit protection — reduces field wiring damage risk
- Proven reliability in HVAC, building automation, and industrial process control
- Long-term Saia ecosystem support — firmware updates and diagnostics via PG5 software
Typical Applications
- Building Management Systems (BMS) — HVAC actuator and valve control
- Industrial process automation — conveyor, pump, and motor on/off control
- Energy management systems — load switching and demand control
- Water treatment plants — solenoid valve and dosing pump control
- Factory automation — signal output to drives, relays, and indicators
System Compatibility
| Platform | Compatible | Notes |
|---|---|---|
| Saia PCD3.Mxxx CPUs | ✅ Yes | Direct plug-in, full diagnostics |
| Saia PCD3 Expansion Racks | ✅ Yes | Up to max I/O per rack rules |
| Saia PCD2 Platform | ❌ No | Different bus connector |
| Saia PCD1 Platform | ❌ No | Incompatible form factor |
| Third-party PLC racks | ❌ No | Proprietary bus |
Selection Guide
Use the following criteria to confirm the PCD3.A465 is the right module for your application:
- Output type needed: Transistor PNP (sourcing) — if NPN (sinking) is required, select PCD3.A460 or equivalent NPN variant
- Channel count: 16 DO — if fewer channels suffice, consider PCD3.A400 (8-ch) to reduce cost
- Load current: ≤ 0.5 A per channel and ≤ 4 A total — for higher loads, use relay output modules (PCD3.A480)
- Voltage: 24 V DC loads only — for 120/230 V AC loads, relay modules are required
- Platform: Must be PCD3 rack — confirm CPU and rack generation before ordering
Quality Assurance & Sourcing
At Konmask.com, every PCD3.A465 unit is:

Replacement & Compatibility FAQ
Q: Can I replace PCD3.A465 with PCD3.A460?
A: Both are 16-channel transistor output modules in the PCD3 series. The A460 is typically NPN (sinking) while the A465 is PNP (sourcing). Wiring polarity must be reversed — not a direct drop-in without field changes.
Q: Is PCD3.A465 compatible with PCD2 CPUs?
A: No. The PCD3 and PCD2 platforms use different backplane bus connectors and are not interchangeable.
Q: Can I use a Siemens SM322 as a replacement?
A: Functionally similar (16 DO, 24 V DC, PNP), but it requires a completely different rack, CPU, and programming environment. Only viable as a full platform migration, not a module swap.
Q: What is the lead time for PCD3.A465?
A: In-stock units ship within 1–3 business days. For out-of-stock items, typical sourcing lead time is 2–4 weeks. Contact us for current availability.
Q: Do you provide a warranty?
A: Yes. New original units carry the manufacturer warranty. Refurbished units include a 90-day Konmask functional warranty.
