What Multispan India Makes
Multispan India (multispanindia.com) is a manufacturer of process control and industrial instrumentation. Its catalogue is built around the measurement, monitoring and switching layer of a plant rather than around computing hardware. The main product families include temperature controllers, general process control instruments, programmable timers and counters, power and energy meters, protection relays, DIN-rail power supplies, and CRYO-related instrumentation. Recent additions such as DIN-rail Power & Energy Meters, DC energy meters for solar and EV applications, earth leakage relays and power quality meters with harmonic analysis up to the 32nd order are aimed at building management systems, energy management and carbon net-zero reporting. Multispan also offers an IIoT platform for cloud-based energy, power management and data logging.
Where Industrial Computers Fit In
Instruments such as energy meters, PID controllers and temperature controllers produce the raw measurements, but they generally do not run SCADA, store historical data, or publish to the cloud by themselves. That work is done by an industrial computer or edge gateway sitting above the instrument layer. A typical architecture is: field instruments and meters → RS-485/Modbus RTU or Modbus TCP → industrial PC running a data logger, HMI/SCADA node or protocol converter → database, dashboard or cloud platform. This is why an automation or energy-management project usually needs both a process control instrument vendor such as Multispan and a supplier of rugged industrial computers.
