PLC Suppliers in Kolkata

Kolkata, the industrial and commercial capital of Eastern India, is home to steel plants, jute mills, thermal power stations, and chemical industries. Its surrounding regions—Howrah, Durgapur, Haldia, Dankuni, and Kharagpur—are major industrial hubs driving the demand for Programmable Logic Controllers (PLCs).

Industries in Kolkata using PLCs:

Steel & Metallurgy – Rolling mills, furnaces, and casting automation.

Power Plants – Boiler-turbine automation in NTPC, WBPDCL, and CESC units.

Jute & Textile Mills – Loom control, dyeing, and material handling automation.

Chemicals & Fertilizers – Continuous process automation and batch controls.

Food & Beverages – Packaging, bottling, and conveyor line automation.

Ports & Logistics – Haldia Port material handling systems.

Types of PLCs in demand:

Compact PLCs – For textile mills and small-scale packaging lines.

Modular PLCs – Widely used in steel and power plants requiring thousands of I/Os.

Safety PLCs – For handling hazardous operations in chemical industries.

Redundant PLCs – Required for continuous operations in steel and power sectors.

Top PLC brands widely used in Kolkata include Siemens, Allen Bradley, Mitsubishi, ABB, Delta, Omron, Rockwell Automation, Schneider Electric, and Phoenix Contact. In heavy industries, Siemens S7-400, Allen Bradley ControlLogix, and ABB AC500 PLCs are preferred for their robustness and compatibility with SCADA/DCS systems.

Key specifications buyers check before selecting PLCs:
