SCADA Field I/O Technician

The SCADA Field I/O Supervisor is responsible for planning, coordinating, and overseeing the execution of field I/O wiring, signal testing, and SCADA integration tasks. This leadership role ensures that all signal loops—from field instruments to SCADA interfaces—are installed, tested, and documented to the highest standards. The supervisor also handles team management, resource planning, quality control, and client/vendor coordination during automation projects.

Key Responsibilities:

• Supervise and manage a team of field I/O technicians during installation and commissioning.

• Plan and assign daily activities related to I/O termination, loop testing, and SCADA tag verification.

• Ensure proper installation of sensors, actuators, and junction box wiring as per project specs.

• Approve loop test results, wiring checks, and ensure conformance to control system architecture.

• Coordinate with automation engineers, SCADA integrators, and PLC/DCS teams for seamless integration.

• Conduct QA/QC inspections on wiring practices, grounding, and tagging.

• Maintain documentation for I/O databases, test reports, redline drawings, and change control.

• Implement and enforce electrical safety protocols and project standards.

Key Focus Areas:

1. Team Leadership & Execution Oversight

   • Assign work, monitor performance, and ensure safety compliance for I/O teams

   • Train junior technicians and enforce best practices in field installations

2. SCADA–Field Integration Management

   • Lead verification of tag data across SCADA and PLC systems

   • Ensure accurate mapping and functionality of input/output signals

3. Loop Testing & Troubleshooting Control

   • Review signal testing (4–20 mA, DI/DO, RTD, etc.) and ensure system readiness

   • Diagnose and resolve field-to-panel signal mismatches or grounding issues

4. Documentation & Compliance

   • Approve and manage I/O loop folders, termination logs, redline diagrams, and commissioning packs

   • Support audits and validation efforts during FAT/SAT or client handovers

5. Cross-Functional Coordination

   • Liaise with contractors, project engineers, SCADA vendors, and QA teams

   • Manage schedule alignment for I/O completion, commissioning, and support phases

Qualifications:

• Education:

  • Diploma or Degree in Instrumentation / Electrical / Electronics Engineering

• Experience:

  • 8–12 years of relevant experience in field I/O, SCADA, and instrumentation projects

  • 2–4 years in a supervisory or lead technician role

• Technical Skills:

  • Strong expertise in:

    • SCADA/PLC I/O architecture

    • Wiring standards and electrical installation practices

    • Loop testing, diagnostics, and field validation

    • Control panel layouts, terminal wiring, and grounding

  • Familiarity with HART/Modbus/Profibus protocols preferred

• Soft Skills:

  • Team leadership, attention to detail, and clear technical communication

  • Ability to manage multiple contractors and report progress to stakeholders

  • Strong documentation and quality compliance orientation
