What is the OPCB-221B and how does it enable remote monitoring of Novatek devices?

The OPCB-221B is an IoT gateway controller that connects Novatek Electro devices with Modbus RS-485 ports to the internet via an Ethernet or Wi-Fi connection, enabling remote monitoring and control through the Overvis cloud SCADA platform. Once installed, you can view real-time parameters, receive fault alerts, change device settings, and review historical data from any internet-connected device — phone, tablet, or computer — from anywhere in the world.

Which Novatek devices can be connected through the OPCB-221B?

Any Novatek Electro device with a Modbus RS-485 communication port can be connected through the OPCB-221B. This includes the UBZ-304 motor protection relay, RPM-416 data logger, OM-310 three-phase power controller, and other Modbus-enabled devices in the Novatek range. Multiple devices can be connected to a single OPCB-221B on the same RS-485 bus (up to 32 devices per bus segment), making it a cost-effective IoT gateway for an entire control panel.

What is the Overvis platform and is it free to use?

Overvis is a cloud-based SCADA and monitoring platform developed specifically for Novatek Electro devices. It provides a web interface for visualising device data, creating dashboards, setting alert thresholds, and downloading historical data. A free tier is available for evaluation and small installations. For larger installations, subscription plans provide extended data retention, more device connections, and advanced reporting features. You can try Overvis for free at overvis.com.

Can I receive SMS or email alerts when my motor or pump has a fault?

Yes. The Overvis platform connected via OPCB-221B supports configurable alerts that can notify you by email or other notification methods when a device reports a fault, when a measured value crosses a threshold, or when a device goes offline. For a remote pump station or unmanned industrial installation, this means you receive immediate notification of a motor trip or voltage fault without needing someone physically on site to observe the panel.

Is technical expertise required to install and configure the OPCB-221B?

Basic electrical installation knowledge is required to wire the OPCB-221B to the RS-485 Modbus network and connect it to your network infrastructure. The Overvis platform configuration is web-based and does not require programming knowledge — you configure device addresses, parameter names, and alert conditions through a graphical interface. Novatek Electro India provides technical documentation and support through intelli-electro.com for installation assistance.
