FOXBORO SCD2200 Remote Terminal Unit – Robust field control for SCADA and process automation

The FOXBORO SCD2200 is a rugged Remote Terminal Unit (RTU) designed for reliable acquisition, control, and reporting in wide-area SCADA systems. From my experience, it’s a good fit when you need dependable I/O at remote sites, protocol flexibility, and secure communications back to the control center—without babysitting the hardware. You might notice that it combines a modular I/O design with industrial-temp performance, which typically makes it a favorite for utilities, pipelines, and power networks.

Application Fields

The SCD2200 is commonly deployed in:

• Water and wastewater networks – Remote pumping stations, reservoirs, flow/pressure monitoring.
• Oil and gas pipelines – Block valve stations, cathodic protection, custody transfer metering.
• Electric power and substations – Feeder monitoring, recloser control, grid telemetry.
• Renewables and microgrids – Solar/wind plant integration and site-level data concentration.
• Industrial utilities – Steam headers, compressed air systems, and remote tank farms.

A utility supervisor told us their biggest gain was cutting truck rolls: with reliable time-stamped data and DNP3 reporting, they could diagnose 90% of alarms before anyone grabbed the keys.

Advantages & Value

• Interoperability – Plays nicely with most SCADA masters via open protocols, reducing integration risk.
• Lifecycle confidence – From my experience, Foxboro SCADA gear tends to have long support horizons and stable firmware branches.
• Cost control – Modular expansion means you scale I/O only when needed; you avoid paying for unused slots.
• Serviceability – Field-replaceable modules help you swap a card in minutes and keep the site running.
• Compatibility – Works with typical 24 VDC control power and standard cabinet hardware many plants already use.

Installation & Maintenance

• Cabinet & mounting – Install on DIN-rail or backplate in a ventilated, dry enclosure. Allow space for cable bend radius and heat dissipation.
• Power & grounding – Use a clean, regulated 24 VDC supply; bond protective earth; segregate signal and power wiring to minimize noise.
• Wiring – Keep analog loops (4–20 mA/0–10 V) shielded and grounded at one end; use twisted pair for RS‑485 over longer runs.
• Surge protection – In many cases, adding surge arrestors on field I/O and telecom lines significantly increases uptime at exposed sites.
• Routine maintenance – Periodically verify I/O calibration, clean dust from vents, review event logs, and update firmware during planned outages.
• Security practices – Change default credentials, segment the RTU network, and log remote access for audit trails.

Quality & Certifications

• Conformity: CE and UL/cUL for industrial control equipment (typical for this model range)
• Environmental: RoHS compliant
• Quality system: Manufacturer operates under ISO 9001 processes
• Warranty: 365-day warranty provided by us

Supported Accessories & Options

• 24 VDC industrial power supplies with battery backup
• Digital and analog expansion I/O modules (4–20 mA, 0–10 V, pulse count)
• Communication modules for additional RS‑485 ports or cellular/serial gateways
• DIN‑rail surge protection for power, Ethernet, and serial lines
• Pre-wired terminal blocks and labeling kits to speed panel assembly

If you plan to standardize across multiple sites, we can help align the SCD2200 module mix (I/O, comms, power) to your typical point lists, so spare holding stays lean and commissioning goes faster.
