Simple, but versatile solution suitable for a wide range of IIoT applications. Our device seamlessly integrates a cellular modem with a 4-relay switch in a compact design. Operators can effortlessly connect via the cellular network to remotely control equipment connected to the relays, either on-demand or based on a predefined schedule.

Our integrated 4-relay load control switch offers a streamlined and cost-efficient approach to remotely managing connected devices. This all-in-one solution, combining a switch with a modem, enables optimal power consumption in closed distribution systems across industrial, agricultural, and various other sectors, leading to significant financial savings.


The Modern Substitute for Legacy Ripple Control Systems

First-generation ripple control systems were limited by one-way communication, with which centralized load control and peak shaving have been performed for many years. Modern real-time Distribution Automation applications and advanced metering solutions require two-way communication and higher data rates than what second-generation PLC systems can deliver. Standardized cellular networks operating in licensed bands constitute a promising technology to address all the performance limitations of other wireless technologies for both metering and DA applications.


Smart Grid – Load Management

Load management has a crucial role in the future of energy management systems. It allows utilities and smart grid operators to balance the supply with the electrical load by controlling the load rather than the power station output. Our product is suitable for all kinds of smart grid applications.

Solar farm operators for the remote control of inverters, in order to balance supply to the demand.

As part of a Demand Response Systems (DR), our load control switch can be used to monitor energy usage in the area and automatically switch off equipment with high consumption such as water heaters or HVAC systems when demand spikes. The 4 relays of the switch can be configured to control electric loads.


Street Light Management

This product enables operators to control public lighting remotely. Upgrade your street light control cabinets with smart features by adding our Load Control Box. It allows fine-tuned control and supervision of all the components including lamps and dimming light intensity to each of the electric cabinets according to particular needs. One box is able to control 4 street lamp groups, which can accommodate hundreds of lamps. This can be done on-demand or according to a scheduled program.


In each control cabinet, our solution provides the following features for maximum smart integration:

  • Street Light control & switching
  • Data collection
  • Switching and operation status
  • Data exchange with OSLP compatible software
  • Scheduled operation / on-demand manual control


Along with these features, advanced monitoring and management processes are included:

  • Power consumption
  • Lamp failure detection
  • Remote management and maintenance
  • IEC 1107 / OSLP protocol
