Wireless Field MOV Control — Haldia, West Bengal

The Wireless Distributed Field Motor-Operated Valve (MOV) Control Extender is designed for reliable, real-time valve automation in industrial environments. It integrates wireless communication and advanced control logic for efficient remote operations. Designed and commissioned on-site from Haldia, West Bengal.

Key Features

Wireless communication (Proprietary protocol using RF in license-free IN865 band)

Real-time monitoring and control

Rugged industrial-grade enclosure flame proof/IP rating (IP65/66/67)

Low-power intelligent control system

Supports integration with SCADA / PLC / IoT platforms

Fail-safe and self-diagnostic capabilities

Technical Specifications

Operating Voltage: 12–24V DC for control station/AP extender
Wireless Range: Up to 1 km² with range extendable for wider coverage as per ordering information
Control Outputs: 2 relay outputs for open/close command per MOV
Control Inputs: 3 digital inputs (Open/Close/Remote-Local) per MOV
Protocol: Modbus RTU over TCP/IP/Serial communication protocol for PLC/SCADA
IP Rating: IP67 outdoor rated
Operating Temperature: -20°C to 70°C

Field Wireless Network

Master Control Station communicates with Slave Controllers using a proprietary communication protocol in the RF IN865 frequency band, with range extendable for wider coverage. Each Slave Controller operates the field MOV through wired control, compatible with any general-purpose MOV using standard wiring practices.

Prerequisite

All MOV should be of usual wiring type with customary wiring options for open/close command and status feedback for open/close/remote-local.

Applications

Industrial MOV control
Oil and Gas industry
Water line MOV

Ordering Information

Models can be configured and the system can be designed based on customer requirements, enclosure type, and integration needs.

Built for Haldia's Oil, Gas & Water Infrastructure

Haldia is a major refining, petrochemical, and port hub, and pipelines and water lines in and around it routinely run through terrain where laying control cable to every valve isn't practical — long distances, road crossings, or sites that grow faster than their original cabling plan. That's exactly the gap this extender is built to close: it lets a control room open, close, and monitor field MOVs wirelessly instead of running conduit to every valve.

The wireless link runs on a license-free RF band (IN865), so there's no recurring spectrum licensing cost, and the master-to-slave architecture means one control station can manage multiple field valves across a site without a dedicated cable run to each one.

We design, install, and commission these systems on-site across Haldia and the surrounding West Bengal industrial belt, including Durgapur, Howrah, and Kharagpur, for oil & gas and water-utility operators who need field MOV automation integrated with an existing SCADA or PLC system, not a standalone gadget that doesn't talk to the control room.

Commissioning & Support

Site survey.We map valve locations, distances between master and slave units, and what your MOVs' existing wiring looks like — the extender is built to work with standard open/close and status wiring, not a proprietary valve type.

RF link planning. Because coverage depends on terrain and obstructions, we plan and, where needed, test RF link range across your actual site before finalizing the deployment layout.

Installation and SCADA/PLC integration. We install the master control station and slave controllers, wire them to your existing MOVs, and integrate with your SCADA or PLC over Modbus RTU/TCP so valve status and control sit alongside the rest of your plant data.

Ongoing support. Being based in Haldia means follow-up service, spares, and troubleshooting are a short trip away, not a multi-day mobilization.

Frequently Asked Questions

Will this work with the MOVs we already have installed?

In most cases, yes — the system is compatible with any general-purpose MOV that uses standard open/close command and status-feedback wiring. We confirm compatibility during the site survey.

How far can the wireless link cover?

Up to roughly 1 km² under typical conditions, with range-extension options for larger or more obstructed sites. Actual range depends on terrain and line-of-sight, which we assess before deployment.

Can it integrate with our existing SCADA or PLC system?

Yes. The system communicates over Modbus RTU with Serial or TCP/IP, which is the standard protocol most SCADA and PLC platforms already support.

What happens if the wireless link drops?

The system includes fail-safe and self-diagnostic capabilities, so a lost link is flagged rather than silently failing — the specific fail-safe behavior for your valves (e.g., last-known-position hold) is configured to match your process safety requirements.

Do you install and commission on-site, or just supply the hardware?

Both. We handle the site survey, RF link planning, installation, and SCADA/PLC integration, with support available afterward since we're based locally in Haldia.
