SAIA 52030C10 / PCD2.W200 – Interface Expansion Module for Saia PCD2 Controllers

The SAIA PCD2.W200, referenced here with assembly code 52030C10, is an interface expansion module designed for Saia PCD2 systems. From my experience, this module is typically used to extend controller connectivity for serial or field-bus style links between the PCD2 CPU and external devices such as drives, HMIs, meters, or building automation peripherals. You might notice that keeping the interface native to the PCD2 platform helps with long-term maintainability—no odd adapters, fewer surprises during commissioning, and cleaner documentation in the cabinet.

Company’s Order Placement Process and Guarantees

• Warranty period: 365 days
• Delivery time: 1 week for in-stock; no more than 1 month at the latest

Key Features

• Native PCD2 integration – Plug-in module for Saia PCD2 controllers; preserves form factor and serviceability.
• Interface expansion – Typically used to add a communication port for device networks or serial links to third‑party equipment.
• Backplane powered – Draws power from the PCD2 base; no separate PSU wiring in most cases.
• Service-friendly design – Front access to connectors and labeling helps speed up installation and loop checks.
• Cabinet efficiency – Compact footprint keeps the I/O bay tidy and improves airflow around the controller.

Technical Specifications

The table lists typical characteristics for the PCD2.W200 family. If you share your CPU model and the devices you plan to connect, we’ll double-check compatibility before shipment.

Application Fields

• Building automation and HVAC panels linking controllers with meters, chillers, and room controllers
• OEM machine integration where the PLC needs a clean serial/field link to drives or instruments
• Energy management systems collecting data from power analyzers or submeters
• Water and wastewater control cabinets needing reliable controller-to-device communications

Advantages & Value

• Reliability – Native module means predictable behavior and fewer adapters that can fail.
• Compatibility – Designed for the PCD2 ecosystem; in many cases it’s a straight drop‑in on existing CPUs.
• Cost control – Reduces engineering time versus external gateways and simplifies documentation.
• Maintainability – Clear labeling and front access speed up fault finding during tight outage windows.

Installation & Maintenance

• Environment – Install in a ventilated cabinet (IP54 or better recommended) with room for cable bend radius.
• Wiring – Follow Saia PCD2 wiring guidelines; segregate low-level comms from power conductors.
• Grounding & shielding – Bond shields at the designated point; fit termination resistors where RS‑485/serial buses require them.
• Commissioning – Verify port settings (baud, parity, protocol) in the CPU project and run a basic comms test with one device first.
• Routine care – Periodically re‑tighten connectors, clean dust, and keep firmware/project documentation aligned with the live configuration.

Quality & Certifications

• CE and RoHS compliant (typical for SAIA control modules)
• UL/cUL suitability for use in industrial control equipment (model dependent)
• Manufacturer’s warranty: 12 months from shipment

If you can share your PCD2 CPU model, intended device protocol, and cabinet constraints, we’ll confirm the 52030C10 / PCD2.W200 match and line up a fast shipment so commissioning stays on schedule.
