Overview
SGT Systems Limited's Factory Automation catalogue gives Bangladeshi manufacturers — from garments and textiles to food & beverage, pharma, plastics and light engineering — a coherent, locally supportable platform for instrumenting their production lines, energy systems and quality processes. The catalogue contains 10 SKUs spanning programmable controllers, human-machine interfaces, SCADA / OEE gateways, machine-monitoring devices, energy meters and production-line controllers.
The pressure to digitise factory operations in Bangladesh now comes from three directions at once: international buyers demanding traceability and sustainability data; local energy and gas costs pushing operators to instrument and optimise utility consumption; and skilled-labour shortages making it cheaper to monitor and control machines automatically rather than to staff them manually. The SGT Factory Automation range is designed to address all three drivers using off-the-shelf, modular products that can be procured, installed and commissioned without a multi-year transformation programme.
Our hardware is designed for the realities of a working factory: 24/7 duty, ambient temperatures of 40°C+ in summer, dusty cabinets, unstable mains supply, and operators who need on-machine touchscreens to "just work". We complement the hardware with a software stack — OEE dashboards, energy analytics, MES connectors — that is open, API-friendly, and designed to coexist with whatever ERP or quality system the customer already uses.
This catalogue describes the product family at a category level. Individual SKU datasheets carry the per-product I/O specifications, certifications and wiring guides.

Field instruments — motor drives, energy meters, sensors, machine controllers — connect to PLCs and edge gateways using the established factory-floor protocols. PLCs handle the deterministic control logic (start/stop, interlocks, recipe execution), while the edge gateway aggregates data from PLCs, HMIs and standalone sensors, calculates OEE in real time, and publishes upward over OPC UA and MQTT. From there the plant SCADA / OEE server presents dashboards to production engineers, and a REST / MQTT layer feeds the customer's MES and ERP for downstream planning, quality and finance workflows.
Industries we serve in this category
- Garments & textiles: sewing-line OEE, boiler / compressor / chiller monitoring, energy sub-metering by floor
- Food & beverage: batch reporting, CIP automation, cold-chain compliance inside the factory
- Pharma: validated environmental monitoring, batch-record automation, audit-ready data
- Plastics & injection moulding: machine-cycle analytics, mould-changeover tracking, scrap reduction
- Light engineering & metalworking: CNC monitoring, tool-life tracking, predictive maintenance
- Packaging and printing: line speed and downtime analytics, integrated barcode / vision quality
Customisation & OEM
Factory automation is by its nature project-driven — every line has its own quirks. Our standard delivery includes a free initial line audit and a paid detailed-design phase that produces a firm bill of materials and a fixed-price commissioning quotation. Beyond that, customisations include: custom HMI screen designs in the operator's language; custom OEE rule sets aligned to the customer's downtime taxonomy; integration with the existing ERP (SAP, Oracle, Microsoft Dynamics) or industry-specific MES; private-label hardware for OEM machine builders; and pre-configured "starter kits" tailored to a sector (e.g. a garments boiler-monitoring kit).
Ordering & logistics
- Lead times: energy meters in stock; controllers, HMIs and gateways 2–3 weeks; full line-automation projects scoped per RFQ
- MOQ: 1 unit for evaluation; project pricing applies from the first commissioned line
- Warranty: 12-month standard, with optional 36-month extended warranty and AMC including on-site response and spares-on-shelf
- Installation: SGT field engineering crews handle commissioning inside Bangladesh; regional projects via vetted local partners
- Commissioning deliverables: as-built drawings, IO list, alarm list, PLC source code (escrow or hand-over per contract)
Support & documentation
Every factory project includes commissioning documentation (as-builts, IO lists, alarm lists), an operator-level training session, a maintenance-level training session, and a 90-day post-go-live tuning window during which we adjust thresholds, dashboards and reports based on real production data. Customers on AMC additionally receive same-business-day response inside Bangladesh, scheduled preventive-maintenance visits, periodic firmware updates and quarterly reports benchmarking the plant's OEE and energy KPIs against earlier periods.

Reference deployments and outcomes
SGT Factory Automation products are deployed across garments, food, pharma, plastics and engineering plants in Bangladesh. A typical garments-factory deployment instruments boilers, compressors, chillers and the floor-level energy feeders, producing a daily energy and utility dashboard that allows the plant manager to see consumption by floor, by hour and by product line. Most customers identify 8–15 % in addressable energy waste in the first quarter of operation — leaking compressed-air systems, over-pressurised boilers running on weekends, idle chillers — and recover the project cost inside 12 months.
A typical packaging-line OEE deployment instruments the line's PLCs and adds machine-side downtime-reason terminals so operators can classify each downtime event. Within the first 90 days customers typically discover that the dominant downtime causes are not what they thought — and that the data-driven prioritisation allows the plant engineering team to focus their improvement projects on the issues that actually move OEE numbers.
OT cybersecurity
Operational-technology cybersecurity is now a non-negotiable requirement for any factory project, especially in export-oriented sectors where international buyers audit suppliers against frameworks like IEC 62443 and NIST. SGT's factory automation architecture is designed around zone-and-conduit segmentation: the plant-floor PLC network is isolated from the corporate IT network; data flows up to the SCADA / OEE server through a single audited conduit; and the SCADA / OEE server is the only system that talks to the cloud or MES, never the PLCs directly. All API integrations use TLS with mutual certificate authentication. Engineering access to PLCs is gated through a jump host with multi-factor authentication and full session logging.
For customers pursuing formal IEC 62443 certification, we provide documentation packs that map our architecture and controls to the relevant requirements and assist with the customer's audit process.
Maintenance and lifecycle
Factory equipment is a long-lifecycle asset, and SGT explicitly designs and supports its automation products for that long lifecycle. Every PLC, HMI and gateway SKU has a published support lifecycle of at least 7 years from launch, with spares availability for at least 10 years. Firmware updates are delivered as part of the AMC and are tested against the previous two major firmware versions to ensure backwards compatibility for customers who choose to defer updates. As-built documentation is delivered at commissioning, and updated automatically by our team on every subsequent change-request engagement so the documentation never drifts out of sync with the live plant.
Frequently asked questions
Can SGT automation coexist with my existing PLC / SCADA?
Yes. Our gateways read data from existing PLCs over Modbus or OPC UA without any change to the existing control logic, which means a brownfield retrofit can be commissioned without disturbing the running plant.
Do you provide PLC source code?
Yes — PLC source code is delivered to the customer at commissioning, or held in escrow with mutually agreed release conditions, per the contract.
How do you support pharma / food-grade validated environments?
For validated environments we follow GAMP 5 documentation and testing practices, including IQ / OQ / PQ packs prepared by our applications engineering team and supplied for the customer's regulatory file.
Can I get OEE data into Power BI / Tableau / SAP?
Yes. The SCADA / OEE server exposes data through REST APIs and direct database connections, and we have reference integrations into the major BI and ERP platforms.
