Industrial Controls - Automation Systems & Components

The four primary types of industrial control systems are: open-loop control systems (no feedback), closed-loop or feedback control systems (uses sensor data to adjust output), distributed control systems (DCS, used for large-scale process control), and supervisory control and data acquisition systems (SCADA, used for remote monitoring and control). Most modern industrial automation combines several of these approaches.

A soft starter controls the voltage during motor startup and shutdown to reduce inrush current and mechanical stress, but runs the motor at full speed once running. A variable frequency drive (VFD) continuously controls motor speed throughout operation by varying output frequency and voltage, offering energy savings and precise speed control for applications like pumps, fans, and conveyors.

Products in this category support a wide range of industrial protocols including Modbus RTU and TCP, BACnet IP, Profibus-DP, Profinet, Ethernet/IP, SNMP v1/v2/v3, RS-485, and DeviceNet. This ensures seamless integration with building management systems (BMS), SCADA platforms, PLCs, and energy management software in both new and retrofit installations.

HMI displays in this category are available with IP65, IP66, and IP68 front protection ratings, along with NEMA Type 4X and 12 enclosure compliance. IP68-rated models withstand continuous dust and water immersion, making them suitable for outdoor installations, washdown environments, and harsh industrial settings requiring reliable operation from -20°C to +70°C.

Power monitoring devices like the DIRIS A series and DIRIS Digiware system provide real-time measurement of voltage, current, energy consumption, power quality, and harmonics to Class 0.1 or 0.2 accuracy. This data integrates with building management and SCADA systems via Modbus, BACnet, or Ethernet, enabling energy cost allocation, preventive maintenance scheduling, and identification of power quality disturbances.

For North American applications, look for UL 98, UL 508, UL 98B (DC), and CSA C22.2 certifications depending on the application type. For international projects, IEC 60947-3 compliance is essential. For renewable energy and ESS applications, UL 98B and DC-21B/DC-PV2 utilization category ratings are critical. REACH and RoHS compliance ensures environmental safety for EU-regulated markets.
