Description
The Siemens Moore 353A4F1NNNNNNA4 is a standalone, microprocessor-based multi-loop digital controller used for managing regulatory, sequence, and batch processing applications. This design level “A” hardware platform executes custom control strategies built through standard function blocks, handling continuous PID loops, ratio control, and complex cascade loops on a single dedicated module.

Configuration Model Breakdown
The specific sequence codes in part number 353A4F1NNNNNNA4 dictate the exact factory-installed hardware and enclosure options built into this unit:
| Position Sequence Identifier | Encoded Value | Configured Hardware Parameter |
| Base Enclosure / Case Style | 353A | Standard Model 353, Design Level A |
| Power Supply Feed | 4 | 24 V DC Power Input (+20%, -15%) |
| Operator Display Faceplate | F | Upgraded Fixed Graphic LCD Faceplate |
| Local I/O Complement | 1 | Standard I/O (3 Analog Inputs, 2 Analog Outputs, 3 Digital Inputs, 2 Digital Outputs) |
| Expansion / Option Board 1 | N | Not Required / Blank Slot |
| Expansion / Option Board 2 | N | Not Required / Blank Slot |
| Network Link Interface | N | Not Required (Standard Modbus RTU RS-485 / Local Configuration Port Active) |
| Removable Memory Option | N | Standard Configuration Board Only (RTC/CB not installed) |
| Modification Options | N | None / Standard Stock |
| Reserved Block | N | Reserved for Future Upgrades |
| Engineering Design Level | A | Design Revision Level A |
| Mechanical Retrofit Flange | 4 | Case with Standard Mounting Hardware & Bezel |
On a recent project involving a chemical feed system upgrade, we ran into an issue where an engineer tried to swap a 120 V AC unit with this exact 24 V DC model without verifying the field cabinet wiring first. Don’t make that mistake—feeding high voltage into this terminal block will instantly destroy the main processor card’s internal power rail.
Well, technically it supports local configuration directly via the front keypad buttons, but it is far faster to build your function block diagrams on a PC using the i|config graphical utility and dump it through the front-panel RS-232 port. Double-check your analog input jumper configurations on the carrier board to ensure they match your 4–20 mA or 1–5 V DC loop signals before sliding the chassis into the case.
Global Logistics and Customs Compliance Information
Exporting legacy control hardware like the Moore 353 line requires explicit classification data to navigate international security screenings.
Regulatory and Export Classifications
- HS Code: 85371091 (Programmable process controllers for industrial applications)
- ECCN: EAR99 (Standard commercial asset; no specific dual-use export license required for non-embargoed destinations)
Intercontinental Freight and Packaging
We regularly ship critical process control modules under FCA (Free Carrier) or DAP (Delivered at Place) terms via express operators like DHL, FedEx, or UPS. Because the internal backplane boards and liquid crystal displays are sensitive to rough handling, the factory-sealed inner box is shipped within a heavy, foam-padded outer corrugated carton to eliminate risk of structural transit damage.
Transactional Pricing and Quotation
The listed price on online B2B marketplaces acts as a spot-market reference estimate rather than a firm contractual commitment. Final commercial pricing varies dynamically based on unit vintage, immediate component scarcity, and current volume requirements.
